摘要

在分析环境地质条件基础上,对永定新河防潮闸工程存在的地基沉降、地基液化、饱和软土震陷等主要工程地质问题进行了评价,分析了软土地区工程勘察方法及存在的问题。采用多种方法确定地基承载力和压缩模量等力学指标,并进行分析对比,就各种方法对一般粘性土、淤泥质土和砂性土等不同土层的适用性作出评价。
The main engineering geological problems, such as foundation settlement, foundation liquefaction, saturation soft soil and quake collapse existed in Yongdingxinhe river tide gate project are evaluated on the basis of analyzing the environmental geological condition. The engineering exploration method in soft soil area and the existing problems are also analyzed, at the same time, many kinds of methods are adopted to determine the bearing capacity of the foundation and the modulus of compressibility and also the analyze and comparison are conducted for them. The adaptability of different soil layers, such as normal cohesive soil and muddy soil are also evaluated.
