摘要
灰岩地区因其地质条件复杂,如土洞、岩溶(溶洞、溶沟、溶槽)、构造(断层、节理裂隙)发育,地下水丰富甚至有地下暗河通道等,严重影响桩基础的选型和施工质量及安全。尤其是对大型电厂主体建筑物的基础,如果对岩土工程条件认识不足,就会造成严重的质量安全隐患和经济损失。本文通过对湖南华润鲤鱼江发电B厂桩基础施工成败经验的分析,针对灰岩地区复杂地质条件下大型电厂桩基设计及施工提出一些经验性意见。
Geologic conditions in karst region are very complicated, for example, earth caves, karstification, tectonic, groundwater and underground river are very rich, all of which would influence on pile types, quality and safety seriously. As to large scale power plant, if there is not a good knowledge of the geotechnical conditions, a fatal loss of economy and safety will be caused. The author analyzes the construction experience of the Liyujiang Power Plant B pile foundation of China Resources Power Co., Ltd. of Hu＇ nan, which will offer some experiential ideas on pile design and construction of large scale power plant under complicated geologic conditions in karst region.
