大面积真空预压加固法处理软土地基技术研究
Technological Research on Treating Soft Foundation with Large Area Vacuum Preloading Method
摘要
Abstract
Vacuum preloading is a method to treat soft foundation. With reference to the data of soft soil foundation reinforcement and settlement control from Shanghai Hongqiao hub project on Beijing-Shanghai high-speed railway, this paper introduces the test section of Hongqiao soft foundation where settlement is caused by placing draining board in the process of vacuum preloading reinforcement, and on-site observation and tests of ground surface settlement and pore water pressure are conducted And the results of observation are analyzed. Finally, the mechanical characteristics and the rule of the settlement of foundation reinforcing measures are analyzed with numerical calculation method based on field test data, and the calculated settlement is close to the measured result.关键词
