真空降水联合强夯法在软弱路基处理中的应用研究

Study on technique of low-energy dynamic consolidation method combined with dewatering used to treat soft roadbed

结合上海市某大面积软弱路基加固实践,对真空强排水联合低能量强夯动力固结法加固粉细砂和下卧扰动软粘土路基的技术进行了介绍,经过加固处理的地基均达到设计要求,通过对加固效果进行的分析,得出一些有意义的结论,为以后类似地基处理提供了参考依据。

The technique of low-energy dynamic consolidation method combined with dewatering for strengthening the disturbed soft soils underlying the hydraulic silty and fine sands is introduced. The foundation after treatment can meet the requirement. The effectiveness is also discussed. All the results given are of great practical value for similar soils improvement in the future.
