百色水利枢纽地下厂房洞室布置

The cavern layout of underground power house of Baise project

百色水利枢纽地下厂房布置受地质条件的限制性较强。基于对洞室围岩认识的深化以及围岩所具有的结构属性 ,介绍招标设计阶段将主变及升压站由初设阶段的地面布置方案优化为地下布置方案后的地下厂房洞室布置情况及其主要特点。经围岩稳定分析及综合论证表明 ,优化后的地下厂房洞室布置方案合理可行。

The layout of underground power house of Baise project is limited by the special geologic condition.Based on deepening of cognition to the cavern wall_rock and its structure attribute, the main transformers and step_up substation are laid out in underground cavern in inviting design stage instead of that on the ground_surface.The analyzing and discussing results for wall_rock stability showed that the layout scheme is reasonable and feasible.
