奋斗水电站花岗岩原位试验研究

In-situ test study on granite of Fendou Hydropower Station

水电工程坝址区的稳定和安全是最关键的因素之一,其强度参数的确定是岩石工程勘察的重点。文中对奋斗水电站右坝肩花岗岩进行原位抗剪试验及混凝土与花岗岩抗剪试验。试验结果表明,各试验点的剪切规律良好,与实测岩体的实际情况基本一致,实验结果为后续工程设计提供了科学依据。

The stability and safety of dam site of hydropower project is one of the most critical factors, and the determination of its strength parameters is the focus of rock engineering investigation. In this paper, in-situ shear tests of granite and concrete and granite on the right abutment of Fendou Hydropower Station are carried out. The experimental results show that the shear law of each test point is good, which is basically consistent with the actual situation of the measured rock mass. The experimental results provide a scientific basis for the subsequent engineering design.
