摘要
软土具有天然含水量大,空隙比高,强度低,易压缩变形等特点。如何对其进行加固改良,使其成为稳定的结构物地基,长久以来一直是专家、学者研究探讨的问题。论文依托斯里兰卡百年来的第一条新建铁路——南部铁路项目,研究PVD堆载预压技术在热带富水软土地区宽轨铁路(轨距1676mm)路基上应用的施工技术要点及质量控制措施,总结出一套满足英标要求、适用于斯里兰卡南部地区的PVD堆载预压处理软土地基的施工方法及质量控制措施。
Soft soil contains high proportion of natural water, large holes ratio, weak strength and high compactibility etc., It is the studying point of the experts and professors for finding out how to strengthen it and make it compatible to be stable foundation of structures. Based on the first new-built railway project of Sri Lanka in past one hundred years——Sri Lanka south railway project, the construction method and quality assurance skills under British Standard, which has been adopted in the soft soil treatment using PVD（Plastic Vertical Drain） preloading method in Sir Lanka south area have been studied and summarized.
