| 摘 要： | 软弱地基轻型井点结合塑料排水板复合加固法是将塑料排水板和轻型井点降水结合起来对软基进行加固的方法,常用的施工工艺有先降水后强夯和先强夯后降水两种.结合靖江新港作业区公用码头软基加固工程,进行两组不同施工工艺的现场对比试验.结果表明先强夯后降水方法施工的地表平均总沉降量要大于先降水后强夯施工方法,前者平均固结度达96.8％,高于整个场地的平均固结度,说明采用先强夯后降水方法施工地基加固效果要优于先降水后强夯.

| Abstract: | It is a composite reinforcement method for soft foundation which combines well point dewatering and plastic drainage plate.There are two main construction technologies for the method including dewatering before dynamic compaction and dynamic compaction before dewatering.Based on the engineering of Xingang Public Wharf in Jinjiang,two comparison field tests are investigated for the two construction technologies.The results indicate that the total settlement of the latter method is larger than that of the former.The degree of consolidation of the former method is 96.8% which is higher than the average value.The observation means that the construction technology of the latter method is better than that of the former. |
