摘要: 本文以实测地应力场数据为基础, 构建了竖井马头门三维数值模型。通过选定若干表征马
头门稳定性评价指标, 对马头门与主应力之间不同方位时稳定性的差异作了批量数值分析, 研究了马头
门稳定与原始地应力场特征之间的关系。结果表明, 马头门走向与地应力场的相对方位关系对其稳定具
有重要影响, 从而为立井马头门设计、支护和稳定性评价提供了依据。

Abstract : Three dimensional numerical model of shaft Ingate is constructed based on the data of meas
ured situ stress field by the paper. Though selecting a number of characterized evaluation index for stability
of Ingate , volume numerical analysis for stability difference is carried in different directions between Ingate
and principal stress , then original relationship between Ingate’s stability and situ stress field characteris
tics is studied. The results showed that shaft’s stability is greatly influenced by the relative orientation rela
tionship between directions of shaft and situ stress field , so that a basis for design , supporting , and stability
