The following are such theories and methods as nonlinear theory considering interaction between support and rock mass , which , based on quantity analysis technology and actual data of initial crust stress , can simulate complex geological condition , carven shape and supporting so that provide important reference for analysis of stability of rock mass around underground carven and design of supporting 随之而来的是考虑支护与围岩共同作用的非线性理论和方法。这些理论和方法一般都以数值分析为手段,以实测地应力资料为基础,能模拟复杂的地质条件、洞室形状及支护措施,从而为地下洞室围岩稳定性评价和支护设计提供重要的参考依据。
