摘要
本文介绍了城市道路软土路基的主要特点,并结合526国道岱山段改建工程详细阐述了水泥搅拌桩在城市道路软基处理中的应用。通过项目地勘资料,针对设计进行了复合地基承载力的验算以及沉降验算,验证符合相关规范要求;同时提出了在施工过程中应注意的工艺要点。最后通过施工后检测,表明施工达到设计及规范要求,证明水泥搅拌桩在城市道路软基处理中具备较好的处理效果。
This paper introduces the main characteristics of urban road soft soil subgrade,and combined with the 526 national highway DaiShan section reconstruction project to elaborate the application of cement mixing pile in urban road soft foundation treatment.Based on the geological prospecting data of the project, the bearing capacity and settlement of the composite foundation are checked and verified to meet the requirements of relevant codes.At the same time,the key points should be paid attention to in the process of construction are put forward.At last,the post-construction inspection shows that the construction meets the requirements of design and specification,and proves that cement mixing pile has better treatment effect in the soft foundation treatment of urban road.
