城市垃圾填埋场振动台试验的数值模拟研究
Numerical simulation for shaking-table test of municipal waste landfills
摘要
Abstract
Based on the previous work of eight large scale physical model experiments of landfill conducted on shaking table, nonlinear numerical simulation for the test is performed subsequently; and the experimental and numerical results are verified and supplemented one another in order to further examine the characteristics of the seismic response of landfill. The follow results can be got: (1) Due to the special sandwich constructions, landfill has two main response frequencies; the peak acceleration responses at top of landfill are obtained in the vicinity of the two main frequencies under horizontal earthquake. (2) When other parameters are fixed, seism-induced permanent displacement of landfill liner is shown to be approximately proportional to the amplitude of input motion. (3) The inclination angle of landfill cover and base slope have significant effect on the critical sliding acceleration of cover and base liner system respectively.关键词
