摘　　要：水闸设计的稳定性,对整个水利工程质量产生着重要影响,面对复杂的地质条件,需要选用合理的水闸地基处理方案,最大限度地保障工程安全。文章以广州市山美陂拦河闸工程为例,对其基础处理方案进行比较分析,最终确定联合使用PHC桩与袖阀管注浆法进行水闸地基处理。实践表明,上述方法不仅可以方便施工过程,还具备较高的安全性,在经济成本上也优于其他方案,能获得较为良好的施工效果,具有一定的应用价值。The stability of sluice design has an important impact on the quality of the entire water conservancy project.In the face of complex geological conditions, it is necessary to select a reasonable sluice foundation treatment scheme to ensure the safety of the project to the greatest extent. Taking Shanmeipi river gate project in Guangzhou as an example,this paper compares and analyzes its foundation treatment schemes, and finally determines to use combined PHC pile and sleeve valve pipe grouting method to treat sluice foundation. Practice shows that the above method can not only facilitate the construction process, but also has high safety,and is also superior to other schemes in terms of economic cost. It can obtain better construction effect and has certain application value.
