【摘要】：静压桩沉桩过程挤土效应一直困扰工程人员,如何加快沉桩引起的超静孔隙水压力消散是目前的研究热点。透水管桩通过沿桩身增设透水孔,联通土体释放超静孔隙水压力,可加速沉桩过程桩周土固结。透水管桩技术将控制沉桩挤土效应及加速超孔压消散的方法耦合至现有技术产品中,起到既实现控制效果,又提升工程效率并节省工程造价的目的,是结合了桩基和排水固结法的优点、极具潜力的一种主动、高效、资源节约导向的桩基施工与地基处理工法。对透水管桩技术在国内外的研究进展进行分析,总结了透水管桩承载性能、透水性能、透水性能优化等方面的研究成果,简要论述了存在的问题及今后的研究方向。
[Abstract]:The squeezing effect of static pressure pile has been perplexing engineers all the time. How to accelerate the dissipation of excess pore water pressure caused by pile sinking is a hot research topic at present. By adding permeable holes along the pile body and releasing excess pore water pressure from the soil, the pile can accelerate the consolidation of soil around the pile during piling. The permeable pipe pile technology coupled the methods of controlling the pile-driving effect and accelerating the dissipation of the excess pore pressure to the existing technical products, which not only realized the control effect, but also improved the engineering efficiency and saved the project cost. It combines the advantages of pile foundation and drainage consolidation method and has great potential. It is an active, efficient and resource-saving oriented method for pile foundation construction and foundation treatment. This paper analyzes the research progress of the permeable pipe pile technology at home and abroad, summarizes the research results of the load bearing performance and the water permeability performance optimization of the permeable pipe pile, and briefly discusses the existing problems and the research direction in the future.
