摘　　要：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方面有着广阔的发展空间 。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.
