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。
In this paper , regarding the analysis of stability factors of majiatian tailings fill dam , namely regional geologic structure , rock - soil body of dam foundation , poor geology phenomenon , leach consolidation and chemical consolidation of tailings , seepage water of dam body and king - size flood water of majiatian tailings reservoir , a preliminary demonstration on probability of earthquake liquefaction and seepage failure of dam bodys tailings sand soil , of the dam body failure resulted from abutment landslide and of the flood water overflowing crest , as well as on the contribution of leach consolidation and chemical consolidation of tailings to the stability of dam body has been performed 通过对马家田尾矿库区域地质构造、库区不良地质观察、尾矿淋滤固结和化学固结、坝体渗透水和库区特大洪水等因素对马家田尾矿堆积坝体稳定性影响的分析，初步论证了坝体尾矿砂土的地震液化、渗透破坏、坝肩滑坡使坝体失稳和洪水漫顶的可能性，以及尾矿淋滤固结和化学固结作用有助于坝体的稳定性。
