| 摘 要： | 采用非线性有限元法研究岩质边坡的动力响应问题，模拟了软弱夹层的材料非线性及断层或裂缝的接触问题，假定岩块弹性体，推导了非线性动力响应迭代格式并编制了适于岩质边坡动力响应分析的三维非线性有限元程序，利用该程序对三峡链子崖危岩体进行了动力响应分析，得出了一些有价值的结论，计算结果与模型试验结果基本相符，证明本文数值计算的正确性。

| Abstract: | Seismic response of rock slope is studied with nonlinear FEM in this paper. The material nonlinearity of thin layer and the contact of faults or gaps are simulated, and rock is assumed to be linear elastic.An algorithm for nonlinear seismic incremental iteration is derived, and a 3-D FEM program for nonlinearseismic response analysis of rock slope is developed. Using the program, the seismic response calculation ofthe Lianziya rock slope in the Three Gorges is performed, and some valuable results are achieved. The numerical results show a good agreement with those obtained from the model test of the slope, Which proveshigh accuracy of the present numerical calculation. |
