摘要

摘要: 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。

Abstract: Pile-net composite foundation is a new kind of soft soil treatment method developed in recent years.As the remarkable effects in control the residual settlement, and differential settlement, it was used extensively in highway engineering.In this paper, According to the pile type, two experimental section were designed to investigate the bearing mechanism and the settlement characteristics of pile-net composite foundation.Based on the test data, the bearing mechanism of soil arch was also analyzed.
