摘　　要：在基坑施工中常会遇到地下水埋藏浅,基坑紧邻构筑物或高路基边坡的情况,为了保证基坑侧壁和相邻构筑物或高路基边坡的安全和稳定,论文结合工程实践,介绍了止水帷幕支护的设计要求和设计方案,重点研究了紧邻重载高路基边坡的基坑壁止水帷幕支护设计,并分析了施工工艺流程及注意事项。结果表明,采用水泥搅拌桩止水帷幕并结合钢筋混凝土灌注桩抗侧力支护手段,能取得较好的效果和稳定性。In excavating foundation pit, conditions of shallow water tables and excavating foundation pit near a building or high roadbed slope. In order to ensure the safety and stability of the side wall of foundation pit and the neighbor building or high roadbed slope, the design requirement and plan of waterproofing curtain were proposed, emphasizing that neighboring heavy load high roadbed slope, the construction process and announcements were analyzed. The result shows that, favorable effect and stability can be obtained applying cement mixing pile waterproofing curtain combined with lateral load resistance support with reinforced concrete bored concrete pile.
