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。
Weak foundation light well point combined with plastic drainage board composite reinforcement method is the plastic drainage board and light well point precipitation combine to reinforce the soft foundation method, commonly used construction technology after the first rammer and the first rammer rammer after precipitation . Combined with the soft ground reinforcement project of Jinggang New Port Public Utility Area, two groups of different construction technology were compared on site. The results show that the average total surface subsidence after the first dynamic compaction method is greater than the first ram after dynamic compaction construction method, the former average degree of consolidation of 96.8%, higher than the average site of the average degree of consolidation, indicating that after the first dynamic compaction Precipitation method Construction foundation reinforcement effect is better than the first after ram ramming.
