The development and prospects of the hydropower engineering geology in China

This paper summaries the development process of geological survey in the hydropower project construction in China. It introduces, on the basis of summing up the experience, the study status quo, contents, methods and evaluation principles of the main engineering geological problems that are commonly encountered in the construction of hydropower projects in China, such as local tectonic stability, the foundation engineering geology for high dam, the stability of surrounding rocks of underground works and the leakage of karst. It includes the study of active fault, the earthquake dangerous analysis and local tectonic stability assessment; the rock classification of engineering geology of dam foundation, the selection of mechanics parameters of construction foundation rocks and the survey of deep and thick overburden layer; the geological structure, and un-stability conditions and stability analysis of high side slope of hydropower project, the slope treatment and monitoring; the classification of surrounding rocks in hydropower project and its stability analysis, the theory of karst leakage in the valley, the selection of dam site in the karst area and the principles of the treatment of karst leakage, and so on. Then this paper puts forward some suggestions for the future survey and study on such engineering geological problems.
