摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which can enhance a soundproof effect by reducing not only vibrations of the rail but also noises from the rail.
SOLUTION: The covering member 8 is detachably attached to the top surface and undersurface of a bottom section R
2 of the rail, and detachably attached to both side surfaces of a belly section R
3 of the rail. In the covering member 8, a sound absorbing layer 9a for absorbing the noises from the rail R is provided inside, and a vibration control layer 10a for suppressing the vibrations generated on the rail R is provided outside. When the layer 9a is formed of a viscoelastic body, it constitutes a flexible spring and an attenuator (dash pot), makes the vibrations from the rail R hardly propagate from the layer 9a to the layer 10a, and converts a part of vibrational energy of the rail R into thermal energy by making viscosity bring about vibration damping, so as to absorb and damp the vibrations. Consequently, the noises, which are emitted outward from the layer 10a, are reduced.

摘要翻译：要解决的问题：提供轨道的隔音结构，其可以通过减少轨道的振动而且减少轨道的噪声来增强隔音效果。解决方案：覆盖构件8可拆卸地附接到轨道的底部区段R 2 的顶表面和下表面，并且可拆卸地附接到腹部区段R SB的两个侧表面上， 3 的轨道。在覆盖部件8中，设置有用于从轨道R吸收噪声的吸音层9a，并且设置用于抑制在轨道R上产生的振动的振动控制层10a。当层9a由粘弹性体形成时，它构成柔性弹簧和衰减器（破折号），使得来自导轨R的振动几乎不会从层9a传播到层10a，并将一部分振动能轨道R通过使粘度产生振动阻尼而进入热能，从而吸收和减弱振动。因此，从层10a向外发射的噪声减小。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vibration cutoff structure which easily conforms to the characteristics of the ground, is good in transportability and workability, and also good in stability after construction thereof. SOLUTION: The vibration cutoff structure (10) is constituted of a groove (20) dug in the ground (1) at a location between a vibration source and a structure which should be protected from transmission of vibrations, and a three- dimensional network body (30) arranged in the groove. The three-dimensional network body consists of wire materials formed of a plastic such as a PP (polypropylene) resin or a PET(polyethylene terephthalate) resin, for instance, and is molded such that the adjacent wire materials are connected together with voids being left therebetween like entangled dry noodles. Therefore, the network bodies different in wire diameter d and in porosity a can be easily produced, and a compression modulus e of the entire network body can be varied in a wide range according to the characteristics of the ground. Further, a nonwoven fabric (40) is interposed between the three-dimensional network body and a wall surface (21) of the groove in order to prevent infiltration of soil into the voids of the three-dimensional network body.

摘要： PROBLEM TO BE SOLVED: To prevent vibration of a columnar structure, and prevent crack and reduction of supporting force generated on a foundation ground caused by vibration so as to prevent collapse of a columnar structure by installing a vibration damping means on one part of the columnar structure. SOLUTION: An elastic damping body 3 is arranged as a vibration means so as to cover a base part on one part of a columnar structure 1. In order to increase a damping effect, elastic bodies whose hardness are different from each other are layered alternately with the elastic body singly or mixedly. In order to prevent vibration from transferring to a lower part, a same damping body 3 as a damping body 2 is arranged on the bottom surface lower part of the columnar structure 1 so as to shut out vibration. It is thus possible to prevent vibration of the columnar structure, and prevent crack and reduction of supporting force generated on a foundation ground caused by vibration so as to prevent collapse of the columnar structure. Also it is possible to prevent vibration environment pollution by preventing vibration from transferring to the foundation ground caused by low frequency ground vibration.

摘要： PURPOSE:To provide a sound absorbing structural body for slab track excellent in all of strength, rigidity, electric insulation and sound absorbing performance. CONSTITUTION:Outer sound absorbing material blocks 10 are arranged on a concrete slab 3 by using first support frames 9, 9 in such a manner that voids are formed between the concrete slab 3 and the outer sound absorbing material blocks 10. Inner sound absorbing material blocks 14, 14 are arranged by using second support frames 12, 12 and a central support frame 13 in such a manner that voids are formed between the concrete stab 3 and the inner sound absorbing material blocks 14, 14. Accordingly, sound absorbing performance is exhibited to the maximum. This can withstand not only damage due to a negative pressure estimated to be 0.02 kg/cm at the time of high speed vehicle passing but also impact force of an ice block dropped from a traveling train. Installation work thereof onto a track is simple, and replacement for maintenance work as well as maintenance and repair becomes extremely easy.

摘要： PROBLEM TO BE SOLVED: To provide a noise reduction structure of a viaduct capable of reducing the noise of structures from the viaduct.
SOLUTION: This noise reduction structure damps the vibration energy of a floor slab E
1 since a vibration damping layer 2 suppresses a floor slab lower surface E
3 because the upper surface of the damping layer 2 is fitted to the floor slab lower surface E
3 . Though the soft elastic material of the damping layer 2 shearingly deforms due to the vibration of the floor slab E
1 , the vibration of the floor slab lower surface E3 is damped by covering a part of the vibration energy into a heat energy by an internal loss due to the viscous resistance of a soft viscoelastic material. Further, since a constraint layer 3 is stacked on the damping layer 2, the deformation of the damping layer 2 is retrained by the restraint layer 3. Since the shearing deformation of the damping layer 2 is amplified and the internal loss of the damping layer 2 is amplified, the vibration damping capability of the damping layer 2 can be largely increased. By stacking damping layers 2 and the restraint layers 3 with low rigidness are stacked, spring-dash pot-mass structure is formed as an physical system, and the vibration is also cut off.

摘要翻译：要解决的问题：提供能够降低高架桥结构噪声的高架桥的降噪结构。解决方案：由于振动阻尼层2抑制了地板坯下表面E 3 ，因此，该降噪结构减小了地板E 1 的振动能量，因为上部阻尼层2的表面装配到地板下表面E 3 。尽管阻尼层2的软弹性材料由于地板E的振动而剪切地变形，但是通过将一部分振动能量覆盖在底板下表面E3的振动中来阻尼，由于软粘弹性材料的粘性阻力而引起内部损失的热能。此外，由于约束层3堆叠在阻尼层2上，阻尼层2的变形被约束层3再次拉伸。由于阻尼层2的剪切变形被放大，阻尼层2的内部损耗被衰减，阻尼层2的减震能力可大大增加。通过层叠阻尼层2和低刚性的约束层3，形成弹簧箱体结构作为物理系统，并且振动也被切断。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which enables a covering material to be firmly fixed to the rail, which facilitates manufacturing and construction, and which can enhance a soundproof effect.
SOLUTION: A right-side covering member 8a is mounted on the right-side lateral surface of the rail R, and a left-side covering member 8b is mounted on the left-side lateral surface of the rail R. After that, a right-side holding member 11a is mounted on the member 8a at a predetermined interval in the longitudinal direction of the rail R, and a left-side holding member 11b is mounted on the member 8b. Subsequently, a bolt 11h is inserted into through-holes 11f and 11g, and a nut 11i is attached to the bolt 11h, so that the members 11a and 11b can be connected together. Thus, even if increasing in thickness and weight, the covering member 8 can be firmly fixed to the rail R by means of a fixing member 11. Consequently, since vibrations generated on the rail R are reduced and acoustic radiation from the rail R is suppressed, a soundproof and vibration-control effect can be enhanced.
