| Abstract: | Taking the north anchor foundation pit of the suspension bridge at the south part of Runyang Bridge as an example, the factors that influence the shear strength of cemented interface between concrete and bedrock are analyzed. The shear tests of the said cemented interface are carried out in the laboratory and in the field. The resilient value and the roughness on the whole bedrock surface and some characteristics and parameters of the bedrock surface are acquired. Through the zoning the bedrock surface is analyzed and the formula for the determination of the shear strength of the whole anchor foundation is proposed. The rationality of the said method to determine the shear strength of the whole cemented interface between concrete foundation and bedrock is discussed by considering multi-factors and tests. |
