软土的主要特征有低强度、高压缩性、流变性和低透水性等。该特征在公路软土地基施工中,主要表现为地基沉降量大,会达到十厘米甚至是几十厘米,尤其是在新疆部分地区,由于软土地基的厚度较大,使之固结的速度很慢,沉降时间较长,在不断增加的荷载作用下会引起地基的不均匀沉降,严重影响公路工程的整体质量,给施工企业和公路养护管理单位造成巨大的经济损失。 The main features of soft soil are low strength, high compressibility, rheology and low water permeability. This feature in the construction of soft ground in the highway, mainly for large settlement of the foundation, will reach ten centimeters or even tens of centimeters, especially in parts of Xinjiang, due to the greater thickness of soft soil so that the rate of consolidation It is very slow and settling time is long. Under the action of increasing load, uneven foundation settlement will be caused and the overall quality of highway project will be severely affected, causing great economic losses to construction enterprises and highway maintenance and management units.
