摘要： PURPOSE: To exclude increase of thickness of members and various reinforcement becoming unnecessary in a complete system to the utmost and construct a reasonable and economical multispan continuous bridge by restraining temporary load applied on the bridge pier or the upper structure during construction. CONSTITUTION: In construction of a multispan continuous bridge, the lower part of a bridge pier 1 of a span in which construction of an arch rib 2 is completed and the upper part of a bridge pier 1 of the next span in which construction is succeedingly executed are obliquely connected together with PC steel 3a. An arch center 4 as a movable support is moved to the span in which the arch rib 2 is constructed, and set between the front and rear bridge piers 1. Concrete for forming the arch rib 2 is placed on the arch center 4. The PC steel 3a is tensed and tension of the PC steel 3b of the preceding span in which the arch rib 2 is already formed is released so as to adjust horizontal displacement generated in the bridge pier 1, and the stress condition in a complete system is nearly attained. After curing, the arch center 4 is shifted to the next span, and the PC steel 3c of the span where introduction of tension becomes unnecessary is removed and diverted.

摘要： PROBLEM TO BE SOLVED: To provide a ground stabilization method capable of controlling the sideways displacement of the ground by consolidation to rationally and economically carry out ground stabilization.
SOLUTION: The depth in the underground direction of every ground improvement body 1 is varied so that the front end in the underground direction of every ground improvement body 1 does not arrived at a supporting ground 2, every ground improvement body 1 is put in order so that the front end section in the underground direction is formed in the shape of an arch, and every ground improvement body 1 is so formed that it becomes one piece of arch in the ground. A natural ground 3 directly under the every ground improvement 1 is constrained in the arch to prevent the diffusion of the stress inside of the ground by load applied to every ground improvement body 1 on the ground surface. The natural ground 3 directly under the every ground improvement body 1 is constrained in the arch to vertical one dimensionally limit the consolidation displacement of the constrained ground, and the load applied to every ground improvement body 1 on the ground surface is made to effectively act as consolidation pressure.

摘要： PROBLEM TO BE SOLVED: To provide a ground freezing method for preventing the occurrence of frost heaving or excessive freezing expansion pressure while reducing a period for forming a frozen ground.
SOLUTION: When joining a shield tunnel, water stop devices 3, 4 provided on shielding machines 1, 2 are used for freezing a surrounding natural ground in a joint area to form the frozen ground. When forming the frozen ground, brine of an extremely low temperature, for example, -80°C is distributed to pasted freezing pipes 31, 41 for freezing the natural ground to form the frozen ground having a required thickness in a short period. After forming the frozen ground having the required thickness, the brine of a gently low temperature, for example, -10°C is distributed into the pasted freezing pipes 31, 41 to keep the frozen ground at a required thickness while preventing the thawing of the frozen ground.
