【摘要】 乌江渡水电站扩机地下厂房防渗帷幕工程地处岩溶发育地区,工程地质条件复杂,水平岩溶、垂直岩溶发育。为确保地下厂房的安全,尽可能减少乌江河水及地下水对它的影响,在地下厂房上、下游各设计了一道防渗帷幕。防渗帷幕施工采用高压灌浆施工工艺,灌浆过程中遇到了注入量大,灌浆难以结束,溶洞等特殊情况,通过采取相应的处理措施,收到了较好的效果。更多还原

【Abstract】 Anti-seepage curtain grouting project of underground powerhouse for Wujiangdu hydropower station enlargement project is located in karsts development area with complicated engineering geological condition,level and vertical karsts development.To ensure the safety of underground powerhouse and decrease the influence of Wujiang river and groundwater on the powerhouse,the anti-seepage curtain is made in upstream and downstream of the powerhouse respectively.High-pressure grouting construction technique is used in the anti-seepage curtain grouting construction.The better results are gotten after some measures have been used to treat some special situations such as large injection,karst cave and so on in the grouting process.更多还原
