桩网复合地基是近年来兴起的一种软弱地基处理方法,因其可有效控制工后沉降和差异沉降而被广泛应用于沿海高标准公路建设中。通过在某公路段中对搅拌桩网复合地基及管桩网复合地基两个分区的现场原位试验,从承载机理、沉降变形等方面对二者进行对比分析,并且结合实测数据对填土中土拱的承载性状进行分析。
Pile-mesh composite foundation is a kind of weak foundation treatment method that has arisen in recent years. It is widely used in high-standard highway construction in coastal areas because it can effectively control post-construction settlement and differential settlement. Through the in-situ test of two sections of the compound foundation of the mixing pile foundation and the composite foundation of the pipe-pile net in a highway section, the contrastive analysis of the two is carried out from the aspects of bearing mechanism and settlement deformation. Combined with the measured data, Soil arching carrying capacity analysis.
