Taking a pumped storage power station in Guangxi as an example,in order to study the development degree of alteration granite in different parts of the project area and judge the strength of the development degree,a set of evaluation criteria for the development degree of alteration granite is established by studying the characteristics of alteration granite in the project area and referring to relevant literature.The standard is used to evaluate the development degree of alteration granite in each main part of the project area.It is concluded that the development degree of alteration granite in the main dam area of the upper reservoir,the water conveyance and power generation system area and the main dam area of the lower reservoir are all slight alteration,while the development degree of alteration granite in the auxiliary dam area of the upper reservoir is extremely strong alteration.The evaluation results are consistent with the on-site qualitative judgment,which shows that the evaluation standard has certain application value.
