我国沿海地区分布有深厚软土层,需通过地基处理来满足工程建设要求。阐述了真空-堆载联合预压法的加固机理和技术要求,通过对比分析指出,真空-堆载预压法对加固沿海地区大面积深厚软基在效果和经济上更有优势,大量的工程应用也表明,真空-堆载预压法处理沿海地区电厂软基是一种非常适用的加固方法,值得推广应用。 There are deep soft soil layers in the coastal area of ​​our country, so we need to meet the requirements of engineering construction through foundation treatment. The strengthening mechanism and technical requirements of vacuum preloading combined with preloading method are expounded. The comparative analysis shows that the vacuum preloading method is more effective and economically advantageous in strengthening the large area of ​​deep soft soil in the coastal area. A large number of projects The application also shows that the vacuum-surcharge preloading method to deal with soft foundation in coastal power plants is a very suitable reinforcement method, which is worthy of popularization and application.
