基于传统真空预压技术,提出采用无砂垫层真空预压法对吹填软地基进行浅层加固,通过现场试验优化施工工艺,分析了真空预压下新近吹填淤泥地基的地表沉降和孔隙水压力,并对比了加固前后土体物理力学指标和地基承载力。结果表明,该方法可快速加固吹填淤泥层,并满足后续工程施工承载要求。 Based on the traditional vacuum preloading technology, the vacuum preloading method without sand cushion is proposed to reinforce the soft ground under soft ground. The construction process is optimized through field tests. The surface subsidence and porosity of the newly dredged silty foundation under vacuum preloading are analyzed. Water pressure, and compared before and after reinforcement of soil physical and mechanical indicators and foundation bearing capacity. The results show that the method can quickly reinforce the silt layer and meet the requirements of subsequent construction.
