摘要： Kubia水电站是西非最大的水电站之一，厂房基坑围岩节理、裂隙较为发育，透水性强，地下水丰富。通过对厂房渗漏情况的统计分析，指出了基岩约束力、沉降性不均、温度变化、设计缺陷等四个主要因素是厂房渗漏产生的原因，并提出了根据不同渗漏情况采取水泥灌浆、化学灌浆和引排的方式进行处理，以供从事类似工程施工的工程技术人员参考。

Abstract: The underground spacing for the Kubia Hydroelectricity Project was experiencing the unexpected water leaking. The evaluation concluded that the confinement of the bedrock, differential settlement, temperature variation and improper design are the major factors that contributed to the unexpected water leaking. The cement and chemical grout and well as drainage design were applied at various locations based on the site conditions.
