核电站反应堆大厅基础常为整体混凝土板,埋深十余米,不论建造在硬基(岩石)或软基(土壤)上在地震荷载激发下不能滑动时就会产生摇摆、局部抬起、倾斜、甚至倾倒、按照常规的线性理论分析,只允许在地基基础之间存在压应力和剪应力,而实际上局部会产生拉应力,尤其是在岩石地基上没 Nuclear power plant reactor hall foundation is often a monolithic concrete slab with a depth of more than ten meters. Whether it is built on a hard foundation (rock) or a soft foundation (soil), it will rock, partially lift, and tilt when it cannot slide under the excitation of seismic loads. Even the dumping, according to the conventional linear theory analysis, only allows compressive stress and shear stress between the foundations of the foundation, but in fact it will produce tensile stress locally, especially on the rock foundation.
