摘要三河口水利枢纽工程是引汉济渭工程两大水源工程之一，岩体抗剪强度特征是边坡岩体主要岩体力学问题之一。为研究边坡岩体抗剪强度特征，在坝肩边坡针对不同岩性不同风化程度岩体开展多组原位直剪试验，试验应力与拱坝实际受力状态相同。通过综合分析7组岩体直剪试验和7组岩体/混凝土接触面直剪试验成果，获得不同岩体抗剪强度参数变化范围，研究了试验成果的影响因素、直剪试验破坏特征，最后对比混凝土/岩接触面直剪试验与岩体直剪试验成果及破坏特征。

Abstract：Sanhekou hydraulic project is one of the two potable water source projects of the water diversion from the Han to the Wei river project，and shear strength properties of the slope rock mass are the main rock mechanics. To research slope rock mass strength characteristics，many groups of in-situ direct shear test for different lithology and weathering degree rock mass were conducted on abutment slope，which loading paths and maximum pressure were the same as the conditions of the arch dam acting on the rock mass. By comprehensive analyzing 7 groups rock mass shear test results and 7 groups interface between concrete and rock shear test results，variation range of the shear strength parameters for different rock mass were put forward and influencing factors of test results，direct shear test failure characteristics were studied. At last，results and failure features of interface between concrete and rock shear test and rock mass shear test were contrasted.
