摘　　要：基于GIS升压站设备小型化和对洞室围岩的新认识 ,介绍招标设计阶段将百色水利枢纽地下水电站的主变压器及升压站布置于地下洞室中 ,在设计中突破了规范和常规 ,以较小的围岩厚度尤其是上覆岩体厚度使布置更为合理与经济。经围岩稳定分析 ,结果表明洞室布置合理可行。Base on the new knowledge about cavity surrounding rock and the small_size for the equipments of GIS ,the main transformers and GIS step_up substation of Baise project are arranged in underground cavity with diabase in the stage of bidding design.The design makes a breakthrough in the standard and convention with less thickness,particularly the cover on the cavities of surrounding rock.The results of analysis shown that the arrangement are resonable and economic,and the cavities arrangement is more closed and characterized.
