摘　　要：有限元、边界元、离散元等各种数值分析方法的不断发展,使得岩体应力的定量计算、分析成为可能。开发岩体应力状态分析软件是地质动力区划课题研究工作的重要内容之一。区域岩体应力计算是原始应力计算,它是以区域构造形式为格架,以地应力测量为边界条件,对于大范围的计算来讲,采矿工程的影响可略去,计算目的是确定区域内的应力集中区、应力梯度区和应力降低区,是进行矿井动力现象区域预测的重要基础工作之一[1]。The deveploment of numerical analysis method such as the finite element, the boundary element and the discrete element, makes the quantitative analysis and calculation of rock mass stress to be possible. Software development of rock mass stress state analysis is one of the important problems of the geo - dynamic division team＇ s research. The analysis of region rock mass stress is the primitive calculation and the important basic work of geo - dynamic region forecast, The region structure form is its framework. The border condition is the surveying of geo - stress,, The influence of mining can be neglected for large region analysis. The intention of calculation is to ascertain the stress concentrated area, the stress gradient erea and the stress reduced area.
