有挡锚链三维应力分析

THREE-DIMENSIONAL STRESS DISTRIBUTION OF THE STUD ANCHOR CHAIN

摘要: 本文应用三维边界元法和三维有限元法对有挡锚链进行了三维应力分析,并将其结果与电测实验数据作了比较,吻合得很好。在此基础上给出了便于工程实际应用的锚链极限应力简易计算公式。

Abstract: This paper analyses three-dimensional stress distributions of the stud anchor chain by the theory of finite element and boundary element. It is basically identical with results of electronic test. Then simple formulas for calculating limit stress used in the engineering design are given and the precision is satisfactory.
