摘　　要：在核电工程的可行性研究阶段,客观准确评价工程岩体稳定性极为必要。岩土工程勘察中,在了解场地基本工程地质条件基础上,分别对3个待选厂址中一定数量的钻孔内岩体进行了压水试验,计算出各试验段的岩体透水性指标,得出压水试验曲线,确定岩体的透水性等级。通过对3个待选厂址区内4个钻孔内压水试验数据结果进行综合分析,得出了岩体透水性相对较弱的厂址,为可行性研究阶段的岩土工程勘察提供依据。In the feasibility stage of the nuclear power engineering, it is very important to evaluate the stability of the engineering rock mass. In the process of geotechnical engineering investigation, water pressure tests have been done based on the engineering geological conditions. The tests were finished in the boreholes of 3 waiting selecting plant sites. The permeability indexes of the rock mass and water pressure curves have been obtained, and then, the grades of permeability of rock mass have also been determined. By analyzing the data of the tests, the plant site with low permeability has been chosen. In this way, the important parameters of the permeability properties were provided for the geotechnical investiga- tion.
