摘要/Abstract

摘要： 外塌陷角坐标系是以岩体外塌陷角α和主应力p0为因变量的岩石力学运算系统。摩尔极限应力圆是以岩石内摩擦角φ和主应力σ1,σ3为因变量的岩石力学运算系统。2个系统的基础力学参数存在对应转换关系。外塌陷角坐标系表示岩体自然塌陷、岩石试验、围岩运动力学关系具有真实统一性。摩尔极限应力圆在岩石试验中能反映岩石基本力学性质，但是几何图形表示的应力不符合一般应力定义，基本公式存在缺陷，岩石试验主、次应力与围岩主、次应力没有建立对应关系。

Abstract: Outer collapse coordination system is a rock mechanics calculation system with outer collapse angle and main stress as its dependent variable, while Moore limit stress circle is with internal friction angle of rock and main stress as ins dependent variable. The relationship between the basic mechanics parameters of the two systems is corresponding conversion. Outer collapse coordination system can describe the authentic unity of nature collapse of rock, rock test and rock mechanics. Moore limit stress circle can describe the basic mechanics characteristics of rock during the rock test. The stress described by geometrical graph is different from normal definition. There is limitation of basic expression. The relationship has not been built up between stress of rock test and stress of surrounding rock mass.

Key words: outer collapse angle coordination system, Moore limit stress circle, stress relationships, comparison
