摘要

断层构造是制约地下工程设计与施工的关键因素。综合考虑复杂地质构造与地下洞室群结构的耦合关系，采用三维地质建模方法建立实现了地层体、断层体与地下洞室群结构的统一模型。基于三维模型提出了断层复杂度的概念，为水利水电工程地下厂房洞室群的选址方案分析提供了一种新的手段。针对地下围岩稳定性问题，提出基于断层与断层、断层与开挖面相互切割的曲面块体识别方法，搜索地下厂房洞室群内可能的失稳区域。上述方法已成功应用在某水电工程地下厂房洞室群分析中，在设计方案优化分析中取得了良好的效果。

Abstract

The fault structure is the key factor constraining the design and construction of underground works. A unified model of the strata

faults

and underground caverns were established within a method of 3D geological modeling considering the coupling relationship of complex geological structures and underground cavern group. A concept of fault staggered and topological complexity is put forward based on the unified 3D model. And a new analysis method is provided to solve the location problem of underground caverns in the design of the hydropower engineering. In light of surrounding rock stability

an identification method of curved surface blocks based on the staggered cut of faults and the excavation faces is proposed to search the instability regions in the underground cavern group. This method has successfully applied to a hydropower engineering with underground cavern group and played an important role in program optimization and rock stability analysis.
