摘要
在沿海地区修建高速公路时,软土地基的处理一直是一个难以解决的问题。在分析前人相关软基处理方法的基础上,结合实际工程,提出预应力管桩联合塑料排水板加固软土地基的加固方法。该处理方法中塑料排水板在复合地基中起到排水通道的作用,两种软基处理方法的结合,使得处理效果更好。同时,还对该方法的加固机制进行初步探讨,且通过现场的工程实例分析,对预应力管桩联合塑料排水板方法加固软土地基的处理效果进行验证和分析,证明该方法适用于工期紧、软基埋深大的软土地基。
The soft soil is hot issue to be solved in littoral for freeway construction.The method,which considers the prestressed concrete tube pile combined with prefabricated strip drain to improve the soft soil,is put forwards by analyzing the investigation and field test.The prefabricated strip drain can be used as a draining channel in the compound foundation.So this method has great effects on in the soft soil treatment.At the same time,the mechanism of the method to improving the soft soil is discussed briefly.The in-situ cases show that the method is a good way to improve the deep soft soil,especially where the construction time for the project is relatively short.
