摘　　要：介绍了北海市乾江围海堤的工程概况,分析并评价了工程的地质特征。部分堤段护脚挡墙坐落于河床浅滩,且基础为淤泥质土、淤泥质中砂等软土基,承载力不足、抗倾抗冲刷稳定性差。在挡墙施工中针对实际工程地质条件采用了打松木桩和抛填块石相结合的基础加固措施,论述了施工方法和质量控制措施,工程加固取得了较好的经济技术效果,确保了工程安全稳定运行。An introduction was made on the general information of Qianjiangwei Seawall Project in Beihai City,based on which the author analyzed the geological characteristics of the project.The banket retaining walls of partial seawall sections fall on shoal where the soft soil foundation consists of muddy soil and silt medium sand with poor bearing capacity,poor overturning-and erosion-resisting stability.In the course of retaining wall construction,pine piles and riprap were used to reinforced the foundation according to the actual engineering geological conditions.The anthor discussed the construction method and quality control measures.The reinforcement renders good econom-ic and technical effects,ensure safe and stable operation of the project.
