摘要
系统分析过水土石围堰下游护坡反滤层的减压作用与护坡稳定性的关系,以几何因素和力学因素建立了反滤层渗透破坏极限状态方程,提出了反滤层设计的可靠性模型及其MonteCarlo计算方法,为过水土石围堰护坡结构的设计提供了理论依据.通过模型试验的对比分析,说明护坡反滤层的结构可靠性分析的可行性,计算模型及其计算方法的有效性.
The relationship between decreasing pressure effect of filter layer under the downstream protection slope concrete slab and stability of protection slope for overflow earth-rock cofferdam, is analyzed systematically. And a limit equation of seepage failure with geometric and mechanical factors, is established. Reliability model and its computational method, which offers a tool of structural design of downstream protection slope for overflow earth-rock cofferdam are put forward. Compared with model test, it shows that the model and computational method of reliability analysis of inverted filter structure stability are reasonable and effective.
