软土地基压缩性高、强度低,直接在软土地基上进行市政道路建设难以满足工后沉降的要求,须对软土地基进行处理。结合珠海横琴新区市政道路建设中的软基处理实际工程,分析了真空联合堆载预压处理的设计参数及注意要点,通过理论计算并结合现场监测资料对软基处理效果进行了分析评价,采用真空联合堆载预压处理后的地基工后沉降满足要求,能够很好地达到软基处理的目的。 Due to the high compressibility and low strength of soft soil foundation, the construction of municipal roads directly on soft ground is difficult to meet the requirements of post-construction settlement, and the soft ground needs to be treated. According to the actual project of soft foundation treatment in the municipal road construction of Hengqin New Area in Zhuhai, the design parameters and points of attention in vacuum preloading with surcharge are analyzed. The effect of soft foundation treatment is analyzed and evaluated through theoretical calculation and field monitoring data, The vacuum combined with preloading pile foundation after settlement to meet the requirements, can well achieve the purpose of soft foundation processing.
