rock cover
3.The computation results indicate that when the earth-rock dam with the straight clay core on thick moraine cover foundation is designed, the design criterion for the earth-rock dam with straight clay core directly built on the bed-rock can be adopted for the design criterion of dynamic stability of dam itself, but the dam feet and the dam clay core feet should be reinforced for static stability.
4.Taking the earth-rock dams with straight clay core constructed on thick moraine cover foundation and directly built on bed-rocks with the same sizes and the same materials for example, two-dimensional dynamic FEM programme is used to contrast and analyze the static stress distribution and dynamic response difference of two types of high earth-rock dams in the intensive earthquake zones.
7.To the house of bricky structure, rock-bottom wall body area is large, the wall body area of superstratum is small, so similar unit, upstairs and downstair cover inside practical area or meeting discriminating; Same layer will tell, although be covered identically inside floor area, cover the unit of the unit inter of horn that compare clip inside usable floor area also is met a few smaller.
