提出了一种用于浅埋式地下结构物抗震设计的简化方法。采用任意侧向位移下地震土压力理论 ,推得在土 -结构相对位移较小的情况下 ,结构物所受的土作用力与它们的相对位移近似成线性关系 ,并提出了确定解析解中需要的地基结构动力相互作用系数的方法。在将土体和结构物均简化为只发生水平位移的粘弹性剪切梁及地震输入为竖直向上传播的剪切波等假设条件下提出了一种分析水平地基中结构物在地震荷载作用下的响应的一维解析方法 ,并用该方法对地震时结构物的位移和土压力及其变化过程进行了计算分析
A simplified method for seismic design of shallow underground structures is proposed. Using the theory of any earthquakes with lateral displacement, we can deduce that under the condition of small relative displacement between soil and structure, the soil forces acting on the structure are approximately linear with their relative displacements, Method of Dynamic Interaction Coefficient of Foundation Structure Required. Based on the assumption that both the soil mass and the structure are simplified as the viscoelastic shear beams with horizontal displacement only and the shear wave propagating vertically upwards, an analysis is made of the effect of the structure on the seismic load And the one-dimensional analytical solution of the response under the earthquake and the method is used to calculate and analyze the displacement and the earth pressure of the structure during earthquake
