【摘要】 滨海某软基具有软土层较厚、预先吹砂回填及邻近场地采用强夯加固等特点,采用了具有针对性的措施进行真空预压法加固;地基监测及检测结果分析表明,真空预压加固后,场地地表沉降较大,软土平均固结度达到设计要求;场地软土物理力学性质得到较大改善,强度显著增强,软基加固效果明显。更多还原

【Abstract】 The soft foundation, which have been taken sand-dredger-fill measures in advance, has deep soft soil layer. What’s more, its surrounding site would be improved by dynamic consolidation. The method of vacuum preloading was used to improve the soft foundation. The monitoring and testing results show that the ground surface settlement is large after vacuum preloading, and the average consolidation degree meets the requirements.The properties of soft soil are greatly improved, The strength is significantly enhanced.The effect of soft foundation improvement is obvious.更多还原
