摘　　要：在淤泥质土条件下进行混凝土预制方桩施工,由于土方开挖引起方桩桩位偏移甚至断桩的情况,常出现在实际工程中,如何采取有效的措施控制桩位偏移是土方开挖的重点、难点。文章通过对一些工程调查分析,结合在实际工程中采取降水、排水,及合理的开挖方式、开挖路线等一系列切实可行的措施,在控制桩位的偏移方面取得良好的效果。In the concrete prefabricated square pile construction in mucky soil, due to soil excavation, square pile location deviation and even broken pile fre- quently occur in the actual projects. How to take effective measures to control the deviation of square pile location is the key and difficult point of soil excava- tion. Based on the analysis of some engineering surveys, this thesis achieves excellent achievements in controlling deviation of square pile location by combi- ning a series of feasible measures for the actual projects, such as precipitation, drainage, a reasonable excavation way and reasonable excavation routes.
