摘要
采用弹塑性有限元法，分析研究了混凝土与基岩胶结面的不同平均应力抗剪断强度对应的真实抗剪断强度，以及混凝土和基岩弹性模量取值对计算真实抗剪断强度值的影响．提出了一些可供现场抗剪断试验和工程设计时选择抗剪断强度的参考意见．
Corresponding to various shear strength with even stress distribution,the real shear strength of cemented interface between concrete and bedrock is studied in this paper by elasto plastic FEM.The effect of Young's modulus of concrete and rock upon the real shear strength is analyzed,and the influence of sample shape on the test result about shear strength is studied too.Some propositions that can be taken as references for engineering practice and in situ shear test are put forward.
