Seismic risk assessment and performance based design for landfills

考虑土工合成屏障的动态界面行为，分析了垃圾填埋场的地震危险性。首先，通过振动台装置的倾斜试验和滑块试验，阐明了土工合成材料界面（土工膜和土工织物）的静、动态特性。然后，通过振动台模型试验，模拟了地震作用下整个土体结构的滑动破坏模式。最后提出了一种基于性能的抗震设计极限平衡稳定性分析方法。

The seismic risk of landfills was analyzed considering the dynamic interface behaviors of geosynthetic barriers. Firstly the static and dynamic behaviors of geosynthetic interfaces including geomembranes and geotextiles were clarified by tilting tests and sliding block experiments using a shaking table device. Then, sliding failure modes of the whole soil structure under seismic motion were simulated by shaking table model tests. Finally a limit equilibrium stability analysis method was proposed for performance based seismic design.
