摘要
软弱地基是一种不良地基。由于软土具有强度较低、压缩性较高和透水性很小等特性,因此在软土地基上修建建筑物,必须重视地基的变形和稳定问题。针对软弱地基的不同构成有很多不同的处理方法,包括有:置换法、排水固结法、灌入固化物法、振密(挤密)法、加筋法等五类。文章主要探讨预应力砼管桩在高速公路软土地基处治上的应用。
Soft foundations are poor foundations. Because of their characteristics of low intensity, high compression and low permeability, the deformation and stability must be emphasized when buildings are built on soft foundations. There are different treatments in terms of their different structures, including replacement; draining consolidation; solid pouting; pressing and reinforcement. This article has probed into the application of pretension concrete stand column on the treatment of soft foundations.
