摘要：Based on anchorage foundation of Ganjiang Highway Bridge situated on weakly weathered argillaceous siltstone, numerical simulation analysis of shear tests were carried out to investigate the shear strength of cemented surface, which is between anchorage foundation concrete and bedrock surface. In order to evaluate the effect on shear strength effectively due to the cemented surface roughness, random distribution of parameters is firstly introduced to quantify the roughness and the Monte-Carlo method is employed to simulate the morphology of cemented surface. Secondly, numerical simulation analysis on shear tests is implemented to study the effect of different cemented surface roughness on shear strength. At last, a new evaluation method of cemented surface shear strength is put forward based on the numerical simulation with random contact interface. In addition, the results from numerical simulation method are compared with the field direct shear test, and it is validated that the results are highly consistent.
