| 摘 要： | 研究发现在岩体基本力学介质中，当沉积板状（层状）岩体的结构和性状符合某些特征时，其力学机理从总体上符合板壳结构的特征。根据这一结论，建立了沉积层状结构岩体隧道围岩破坏模型。采用该模型具体分析了深部直立沉积层状岩体中的地下工程围岩在其长度远大于直立高度的情况下岩体中的层状破裂问题。并根据地下结构失稳概率分析原理，建立了直立沉积层状围岩稳定的极限状态方程。

| Abstract: | When tectonic pattern and characteristic of platy structure rock-mass met some conditions,its mechanical principle generally can be analyzed by board & shell theory.Based on the achievement,stress distribution in platy structure rockmass was studied when length is much more than height of underground engineering in vertical stratified structure strata,According to reliability analysis principle of engineering structure,equation of stability probability analysis of upright stratified strata and its calculation methods was researched. |

| Keywords: | Platy rock-mass mechanical media theory of plat and skull damage model |
