介绍了三峡二期厂坝工程常规砼施工时 ,采用不同浇筑方案的原位抗剪试验研究 ,内容包括 :水平剪应力与水平位移的关系 ;水平剪应力与垂直应力的关系 ;残余抗剪强度与垂直应力的关系 ;摩擦抗剪强度与垂直应力的关系 ;摩擦水平应力与水平位移的关系。试验研究成果表明 :层面不铺砂浆 ,直接浇筑富浆砼 ,其层面的胶结质量可以满足设计要求。这为三峡二期厂坝工程采用塔带机入仓提供了依据 This paper introduces the in situ shear tests of different pouring schemes in the conventional concrete construction of the Three Gorges Project Dams. The contents include: the relationship between horizontal shear stress and horizontal displacement; the relationship between horizontal shear stress and vertical stress; the residual shear strength And vertical stress; friction shear strength and vertical stress; friction horizontal stress and horizontal displacement. Experimental results show that: the level of non-mortar, direct cast rich concrete, the level of cementation quality to meet the design requirements. This provides the basis for the tower crane entering into the warehouse of the second phase of the Three Gorges Project
