摘要
真空预压法已在许多国家用于土壤改良和土地复垦工程。文章依托沿海地区广东省湛徐高速公路乌石支线工程的高液限黏土地基处理项目,对真空预压加固软土地基的施工技术和加固机理进行了分析。通过真空预压法加工处理前后的室内土试验,比较了高液限黏土实验前后的物理性能指标和抗剪强度指标的变化,验证了真空预压法是处理高液限黏土地基的有效手段,为真空预压技术的区域发展和推广提供了一定的参考。
Vacuum preloading method has been used in soil improvement and land reclamation projects in many countries. Based on the high liquid limit clay foundation treatment project of Wushi branch line engineering of Zhanxu Expressway in Guangdong Province, this paper analyzes the construction technology and reinforcement mechanism of vacuum preloading to reinforce soft soil foundation. Through the indoor soil test before and after the processing by vacuum preloading method, the changes of the physical performance index and shear strength index of high liquid limit clay before and after the test are compared. It is verified that vacuum preloading method is an effective means to deal with high liquid limit clay foundation, which provides a certain reference for the regional development and promotion of vacuum preloading technology.
