摘　　要：水泥土挡墙是一种常用的基坑支护形式,既能挡土,又可隔水,施工方便,经济实惠,但如在基坑开挖时增加坑外堆土荷载,就会对其产生附加侧向压力,从而影响支护结构的安全。结合工程实际,介绍坑外堆土对水泥土挡墙的影响分析及应对措施,以供类似工程参考。Cement soil retaining wall is a commonly used form of foundation pit support,which can both retain soil and water,be convenient and economical in construction,but if the pile load outside the pit is increased during excavation,it will produce additional lateral pressure on it,thus affecting the safety of the supporting structure.Based on the engineering practice,this paper introduces the influence analysis and countermeasures of the pile of soil outside the pit on the cement retaining wall for the reference of similar projects.
