| 摘 要： | 气垫式调压室对降低施工难度,最大限度地保护生态环境有着无可比拟的优势。但调压室对洞室的埋藏条件、岩体的地应力及渗透性要求较高。岗曲河二级水电站气垫式调压室拟选部位出露白云质灰岩及火山碎屑岩,因岩性差异导致围岩的工程地质条件差异较大,文章结合该工程对不同岩性条件气垫式调压室的工程地质条件进行了探讨。

| Abstract: | Air cushion surge chamber has an unrivaled advantage in decreasing the construction difficulty and protecting the ecological environment to the utmost.However,it puts high requirements on tunnel buried conditions,rockmass geostress and permeability.For Ganquhe II hydropower project,there are exposed dolomitic limestones and volcanoclastic rocks in the proposed location of air cushion surge chamber,and the engineering geological conditions of surrounding rocks are very different due to lithological differenc... |
