摘要
:沿海地区海相沉积的软土地基加固以排水固结为主要方法 ,但随着工程要求的提高 ,加固方法也不断发展变化。综合讨论了真空联合堆载预压法的基本原理、加固特点与效果 ,该法利用真空预压法与堆载预压法加固效果可以叠加的原理 ,在超软基上可以获得较真空预压法更大的预压荷重 ,获得更佳的加固效果。同时结合一些工程应用实例具体分析了真空联合堆载预压法的应用效果与发展前景。
The main method to treat the soft foundation of marine deposits along the coast is drainage consolidation.It is developing with the increasing need of the engineering projects.The primary principle,reinforced characteristics and effect of the vacuum and embankment preloading are discussed synthetically in this paper.This method using the principle of the effect of vacuum preloading and embankment preloading can be superimposed,so it can get bigger preloading load and better consolidation effect than vacuum preloading.At the same time its effect and foreground are analyzed in some engineering cases in this paper.
