摘要
本文论述瀑布沟土石坝及坝基防渗墙在施工完建、蓄水至正常高水位、水位骤降及７．５度，８度地震烈度等不同设计条件下的离心模型试验。得出不同坝高的土石坝及防渗墙各部位的应力、变形值。采用有限元计算，并和有关工程的原型观测资料进行了对比分析。
Centrifugal model tests for earth-rock dam and concrete cut-off wall built in deep overburdenin Pobugou Project under conditions of sudden drawdown of reservoir level and earthquake after com-pletion and reservoir storage are described. Values of stress and strain in diflerent dam heights and atdifferent parts of cut-off wall are measured and compared with those calculated by finite elementmethod and observed from prototype of some projects.
