本文选取双线型弹塑性加载、可变形卸载的土壤模型,分析了浅埋土中梁式弹塑性结构受地面冲击波荷载作用的动力响应,计算了土中由压缩波相互作用而形成的弹塑性弱间断边界,给出了可供设计用的土中结构动力相互作用系数曲线。
In this paper, the bilinear elasto-plastic loading and deformable unloading soil model is selected. The dynamic responses of beam-type elasto-plastic structures in shallow-buried soil subjected to ground shock wave loading are analyzed. The elasto-plasticity formed by the compression wave interaction in soil is calculated. The weak discontinuous boundary gives the dynamic interaction coefficient curve of the soil in the design.
