Abstract

Abstract: This paper make some revisions on Drucker-Prage Criterion on the basis of various expression toHoek-Brown Criteria, and deduce rock mass constitutive function which is consistent to revisory Druck-er-Praser Criterion, which does unportant effect on rock mechanics and its application.

Key words: rock mass, brittle failure, Hoek-Brown Criterion, Drucker-Prager Criterion, constitutivefunction

摘要： 本文基于对Hoek-Brown准则的几种不同表述形式，从其主应力空间的曲面形状提出了对Druk-er-Prager条件的修正，并推导了与修正的Druker-Prager条件相关联的岩体本构模型，对推动岩石力学理论研究及应用具有重要意义。
