The proposals of reinforcement on multilayer masonry-concrete structure office buildings in the high-intensity earthquake region on aspect of seismic design are put forward.

Geological Analysis and Geomechanics Analog Study of Mountain Deformation-Failure Mechanism in High Earthquake-Intensity Area;

One kind of resist-overturning equipment with little stiffness in horizon and energy-dissipation in vertical is designed,for large height-width ratio rubber-bearing isolation structure may have potential overturning danger in zone of high fortification level.

In order to improve the dam s global stability under the engineering background of high earthquake intensity and complicated geologic condition,the dam and power plant are combined together.
