国内真空预压法加固软土地基的现状与趋势

真空预压法作为一种近年来兴起的软基处理手段，已成为排水固结法中的重要组成，其适用范围日益扩大，真空预压法的机理、计算方法、效果检测、施工工艺在大量的实验和实测资料对比的基础上不断成熟，真空预压法在微观机理以及三维分析方法等有着广阔的发展空间，同时应考虑其环境效应问题。

Current Situation and Tendency of Improving Soft Foundation by Vacuum Preloading

In this paper, vacuum perloading, a newly developed means of treating soft clay, is introduced which has become an important of discharge consolidation. The method will be applied in an increasingly wide range of engineering. Its mechanism, calculation methods, inspection of effects and working technology have been improved continuously, based on the comparison between a large number of experiments and the field results. It is pointed out that the method will give wide scope to the aspects such as microstructure and three-dimension analysis and its environment effect should be considered.
