摘　　要：某地铁车辆段的基础设计中,由于厂区地势低洼,属于大面积填土地基工程,设计最终采用压实地基及柱锤冲扩级配砂石桩复合地基。由于本工程大面积填土地基处理的体量大,所以,地基处理方法的不同对工程质量、工期及造价的影响非常大。在本地基处理设计过程中和有关各方进行了充分的论证和调研,采用切实可行的地基处理设计方案,在确保工程质量的前提下缩短工期、降低投资成本。该设计可供同类工程参考。In the foundation design of a metro depot,the compacted foundation and the graded sand-gravel pile composite foundation with column hammer punching and expanding are used in the final design because of the low-lying site and the large area of filling foundation.Because of the large volume of the large-area filling foundation treatment in this project,the different foundation treatment methods will have a great impact on the quality,duration and cost of the project.In the process of foundation treatment design and relevant parties have carried out full demonstration and investigation,and adopted feasible foundation treatment design scheme to shorten the construction period and reduce the investment cost on the premise of ensuring the quality of the project.The design can be used as a reference for similar projects.
