摘要:
真空预压技术已广泛应用于软土地基处理中,但都基于被处理的地基土有一定的强度.天津滨海新区目前正在进行大面积吹填造陆工程,其成分主要为细粒土,含水量高,强度极低,传统的真空预压技术难以直接进行工程施工.为了解决这一问题,采用土工布和海绵等与软式透水管结合作为真空预压新型水平排水体,直接在新近吹填场地进行地基处理.模拟及现场验证试验结果表明:真空预压改进技术对处理吹填软土效果明显,且技术可行,值得在工程实践中作为新近吹填软土前期地基处理应用.
Abstract:
The technology of vacuum preloading has been widely used in soft soil foundation treatment,which is based on the processed foundation soil with certain strength. Large scale reclamation enginerring is now carried out in Tianjin Binhai New Area,which main components is fine-grained soils with high water content and low strength,so the traditional vacuum preloading technology is difficult to meet the needs of engineering construction. In order to solve this problem,geotextiles and sponge associated with flexible permeable were used as new horizontal drainage materials of vacuum preloading to directly carry out the foundation treatment of soft dredger fill. Simulation and field test shows that by using improved technology in vacuum preloading,the effect of treatment is obvious and the improved technology is also operational,so the method can be used as early foundation treatment of soft dredger fill in engineering practice.
