一、前言真空排水预压法是近几年来重新发展起来的一种地基加固方法。该方法加固软基的基本原理早在40～50年代由瑞典皇家地质学院W·Kjellmano教授阐明。但其施工工艺的完善解决及其付诸实施才是近期的事。交通部第一航务工程局科研所在这方面做了不少工作。南京水利科学研究院做了现场实验、室内模型试验及理论计算分析等工作,还着重进行了工艺性的研究,使这一加固技术日臻完善。
I. INTRODUCTION The vacuum drainage preloading method is a foundation reinforcement method that has been redeveloped in recent years. The basic principle of this method for reinforcing soft foundations was elucidated by Prof. W. Kjellmano of the Swedish Royal Institute of Geology as early as the 40s and 50s. However, the completion of its construction process and its implementation are the most recent. The research department of the First Navigation Engineering Bureau of the Ministry of Transport has done a lot of work in this area. Nanjing Hydraulic Research Institute did field experiments, indoor model tests, theoretical calculations, and other work. It also focused on technological research to make this reinforcement technology perfect.
