坝体土工膜防渗结构抗滑稳定研究现状和前景

Slide prevention and stability of anti-seepage structure of dam with geomembrane:studies and prospect

土工膜在工程中应用很多,但对使用经验进行总结并提高到理论上认识还很少。根据土工膜的工作机理、材料特性、工程边界条件和破坏模式,针对坝体土工膜防渗结构的稳定计算和分析方法有待于进一步研究。针对工作实践中存在的具体问题,对坝体土工膜防渗结构抗渭稳定进行了研究,其研究成果可指导土石坝坝体土工膜防渗结构的设计,并为进一步优化施工提供依据。

The application of geomembrane in water project construction has been popular, but we lack of summary of experiences and theories of its application. Further studies is necessary for the calculation and evaluation method of stability of seepage-prevention structure of dam bodies, based on its working mechanism, material feature, boundary condition and damage mode. Considering the specific problems existed in practice, this study may provide a guidance for the design of seepage-prevention structure of earth-rock dam, or base for optimizing construction.
