Practices and researches of soil exploration under complicated topographic and geologic conditions

Under complicated geographic and geologic conditions construction of water resources and hydropower projects water will be difficult,especially during the survey the design periods.However,to find out the complicated situation of the engineering area is engineers,main mission and also the important.How to basis for the feasibility of projeats under the complicated find out geographic and geologic conditions for engineering geology,hydrologic geology is an important topic for geologic.This paper is a summary of mettpds,analysis and evaluation of water resources and hydropower projects under complicated geographic and geologic conditions.
