摘要
国内外大量的文献资料和作者的野外现场调查表明，滑坡堵江成坝形成堰塞湖在山区一带广泛发育。研究发现堵江滑坡作坝存在的工程地质问题，主要包括坝体的渗透变形、稳定性、沉降及不均匀沉降和砂土液化问题。对上述工程地质问题进行探讨，并对堵江滑坡坝进行实例分析。
A number of internal and external literatures and of in-situ investigation of indicate that landslide dams and dammed lakes distribute widely in mountainous zones.The engineering geologic problems of landslide damming, mainly including infiltrational deformation,stability,settlement,and liquefaction of sand layer are discussed in this paper,and its utiliaztion is analysed on the basis of some actual samples.Therefore,this paper provides a guide for the exploration of landslide dams and dammed lakes.
