摘要： PROBLEM TO BE SOLVED: To provide a structure for preventing the lateral flow of the ground that can reduce a construction period and a construction cost by reducing an improved area of the ground after securing an improving effect on the lateral flow of the ground almost equally to or better than a conventional method of uniform construction over the whole object area. SOLUTION: The lateral flow preventing structure for preventing the lateral flow of the ground by soil improvement is installed in front of a soil improving body directly under a structure, for instance. Unimproved areas 6 of elliptic shape or the like in a plan view are interspersed in the improved area 5, and arches 7 are formed in a flow direction x in the improved area 5 by the shape of the unimproved areas 6. The arches of the improved area 5 are composed of precast block frames, blocks for improvement or sheet piles. Horizontal load F is resisted by the whole of such a soil improving body 4.

SOLUTION: An installation face 13 on a sea bottom 17 is leveled to install a caisson 1, and inside filling sand 9 is charged between an external wall 6 and an internal wall 4. Next, a hole 23 is formed in the lower part of a hole 11 formed in the bottom face 10 of the caisson 1 using a double casing 19. A steel frame basket 27 is provided inside the hole 23 and the caisson 1, concrete 29 is placed, and inside filling sand 33 is charged on it. Furthermore, lid concrete 35 is placed on the inside filling sand 9 and the inside filling sand 33, and upper concrete 37 is placed in the vicinity of the upper end of the caisson 1 to complete a breakwater 39.

摘要： PROBLEM TO BE SOLVED: To obtain a desired isolating effect on seismic activity with a relatively simple bearing structure, and to cope with the settlement of a foundation placed on a soft foundation ground, a differential settlement occurring between foundations, the sideways move of a ground and the like in a construction, such as an artificial ground built with structures. SOLUTION: The artificial ground 1 comprises platforms 2 floated on the water surface, and piers 3 erected on footing pile foundations. In the artificial ground 1, a supporting beam 12 formed on the upper part of the pier 3 and the upper surfaces of the platforms 2 are coupled via suspension rods 13 and universal joints 16, 17, to support the platforms 2 in a suspended manner so that they can rock. When an earthquake occurs, locking of the platforms with rock preventive devices 14 is released to extend the natural frequency of seismic waves and reduce seismic movement transmitted from the foundation ground. Also, the length of the suspension rods is adjusted to cope with the settlement of the foundation, the differential settlement occurring between foundations, the sideways move of the ground and the like.

摘要： PROBLEM TO BE SOLVED: To obtain sufficient sliding resistance and cut-off performance of a caisson revetment, caisson breakwater, and the like, by providing relatively small caissons. SOLUTION: The caisson revetment is comprised of caissons 1 set on a rear side of the revetment, wave dissipating works 2 set on the sea side, lower concrete 3 on which the caissons 1 are rigidly set, caisson concrete covers 4, and upper works 5. After setting the caissons 1 on the lower concrete 3, shearing key concrete portions 7, 8 which are erected from the lower concrete on the front side (sea side) and the rear side of the caissons 1, respectively, by a predetermined height, and formed of plain concrete or reinforced by reinforcements, etc., are placed together with the lower concrete 3 in one body. The thus placed shearing key concrete portions 7, 8 on the front and rear sides are used as shearing keys of the caissons 1.
