真空排水预压加固软弱地基技术是加固大面积软粘土的一种较好的方法。尽管我国对此法的大面积研究、试验起步较晚,但经国內许多单位的不断探索与实践,目前已达到世界先进水平。本讲座计划分两期发表,本期先向读者介绍第一部分。 The technology of vacuum drainage preloading to reinforce the soft foundation is a better way to reinforce large-area soft clay.

This lecture is planned to be published in two phases. In this issue, the reader is introduced to the first part.
