| 摘 要： | 基于土体与地下结构动力相互作用分析法，从考虑地下结构抗震的位移响应特性入手，引入剪应变传递率这一新概念。通过大量的数值模型试验，提出了剪应变传递率的经验计算公式，总结了利用剪应变传递率法进行地下结构抗震设计的一般步骤，并通过工程实例验证了这一方法的可行性。

| Abstract: | Based on dynamic interaction analysis between soil mass and a underground structure,from the consideration of displacement response characteristics of the underground structure against earthquake action, a new concept-shear strain transmission ratio(SSTR)was introduced.By means of a large number of numeri- cal model tests,empirical formula related to SSTR was proposed and general procedure that SSTR method can be used for seismic design of underground structures was summed up,thereafter a practical example ... |
