摘要

摘要: 根据实验室的抗剪强度试验, 本文对巴顿方程进行新的讨论并提出新的评价方法。实验室完成了一组岩体结构面的抗剪强度 (, )试验后, 利用抗剪强度资料来模拟巴顿方程的三个参数 (, JRC, JCS)在理论上可以用偏导数求解, 但由于巴顿方程的特殊性, 实际上是不可能的。

Abstract: This article gives a new discussion and a new evaluation method about the three parameters of the Barton equation, according to tests of the shear strength in some laboratories. When the shear strength (, ) of a discontinuity in a jointed rock mass is obtained, the problem how to stimulate three parameters (, JRC , JCS) of the Barton equation should be solved theoretically. But it is impossible to apply the partial derivative equation for solving the problem because of the specialty of the Barton equation. On the basis of discussion of the Barton equation, this article applies the least square method and compiles some programs to solve the problem, and a very good result is gotten.
