真空联合堆载预压法加固软基的应用及施工工艺
|
摘要
真空联合堆载预压法是一种有效处理沿海地区修建高速公路工程软弱地基处理的方法,具有加快固结、工期短、节省土方等优点。本文对真空联合堆载预压法在加固软土地基的应用发展及加固原理进行了总结,对真空联合堆载预压法在高速公路工程中的施工工艺进行了阐述,并对其施工工艺中的不足给出了可行的解决方法,为真空联合堆载预压法在高速公路上的施工及应用提供了参考。
Owing to the advantages of quickening consolidation, short construction terms and saving earthwork, the vacuum-load preloading method is applied to deal with soft foundation of motorways in the coastal areas. In this paper, the application condition,strengthening mechanism and construction technology of vacuum-load preloading method are summarized and expounded in detail, and a workable proposition is proposed to solve the insufficient of construction technology, which provides reference for the future construction and application of the vacuum-load preloading method.
