摘要在岩体基本力学介质中，当板状岩体的结构和性状符合某些特征时，它的力学机理从总体上能够采用板壳理论进行分析。根据这一成果，具体分析了直立层状岩体中的地下工程，在其长度远大于直立高度的情况下，岩体中的应力分布问题；并根据工程结构可靠性分析原理，研究了直立层状岩体的稳定概率分析方程和计算方法。

Abstract：When the tectonic pattern and characteristic of rockmass with platy structure meet some conditions，its mechanics mechanism can generally be analyzed by plate and shell theory. Based on the achievement，the stress distribution in rockmass with platy structure is studied for the underground engineering in vertical stratified strata，with length much longer than the height of chamber. According to reliability analysis principle of engineering structure，the equation of stability probability analysis of upright stratified strata and its calculation methods are studied.

Key words： blocky rockmass mechanics media plate theory stability probability
