| Abstract: | The shear strength parameters of the contacting surface between bedrock and anchor concrete is obtained through in-situ shear test at the Aizhai Suspension Bridge.The testing results show that there is significant cohesion on the contacting surface between full weathered rock and concrete because of the rough contacting surface.The available shear strength parameters of the contacting surfaces between concrete and full to slight weathered rocks on the anchor base according to the testing results. |
