悬索桥锚碇摩阻力现场试验研究
Testing study on base resistance of the anchors at a suspension bridge
摘要
Abstract
The shear strength parameters of the contacting surface between bedrock and anchor concrete are obtained through in - situ direct shear test at the Aizhai suspension bridge. According to the testing results, the curves of shear stress versus displacement under different normal stresses were obtained, at the same time, the shear strength parameters of c and φ are suggested for the contacting surfaces between concrete and slight weathered rocks on the anchor base at the side of Chadong, and the shear strength between the weak structural surface of the bed rock at the side of Jishou was also presented. The test results can provide important references to design and construction of concrete anchor. This study provides reference to construct and design for other similar projects.关键词
