摘　　要：随着经济和社会的发展,对道路运行过程沉降变形的要求越来越严格,而道路工程软土路基处理设计主要以工后沉降为控制指标,如何在保障设计工后沉降满足规范要求条件下,采用最经济合理的处理方式是设计师须充分考虑的。该文通过一例东莞市软土路基处理工程的设计实践,结合软土路基在车辆荷载下的受力特点,成功采用了钉型搅拌桩复合地基处理软土路基,降低了工程总投资,对类似路基处理工程设计起到重要的借鉴意义。With the development of economy and society,the requirements for settlement and deformation during road operation are becoming increasingly strict;The design of soft soil subgrade treatment in road engineering mainly focuses on post construction settlement as the control index.How to adopt the most economical and reasonable treatment method while ensuring that the post construction settlement meets the requirements of the specifications is something that designers must fully consider.This article presents a design practice of a soft soil subgrade treatment project in Dongguan City,and combines the stress characteristics of the soft soil subgrade under vehicle loads.The nail-shaped mixing pile composite foundation is successfully used to treat the soft soil subgrade,reducing the total investment of the project and providing important reference for the design of similar subgrade treatment projects.
