This paper introduced the design,measurement accuracy and operation of the automatic external deformation monitoring system for dam slab and spillway of Lianhua hydropower station.

Based on example,the paper mainly approached how to treat thick and soft groundsill on which earthrock dam or concrete face rockfill dam was build;the results from FEM showed that 25m of these two kinds of dam may be built on thick and soft groundsill if the groundsill was well treated,but earth-rock dam was better.

The application of SR waterproofing materials and SR joint seepage prevention system to second-stage concrete face vertical fracture and fractures around toe slab at the face rock-fill dam of Dongba Hydropower Station is reviewed in this paper.

Critical face rock-fill dam engineering technology as well as scientific and high-efficient construction management in Dongba Hydropower Station construction are introduced in this paper and serve as a reference for similar projects.

Take one concrete-faced rockfill dam for example, the numerical simulation for seepage field of the dam is done with the common finite element program ADINA,and calculates the seepage flow of the dam under many different situations.

In this paper 3 Concrete-faced Rockfill Dam (CFRD), Gouhou Dam, Zhushuqiao Dam and Chengping Dam in China are taken to discuss the importance of drainage and filtration.

Influence of narrow-valley formation on the mechanics property of the 200m high CFRD;

FEM analysis for crush sidewall of SHUIBUYA CFRD Dam;

Study on siltation self-healing watertight structure for super high CFRD;
