摘要
泥岩作为代表性的软岩,极易受到外界影响(如浸水、长期暴露等因素)而发生物理力学性质的变化。作为重要的工程参数,地基承载力的确定是工程勘察阶段的重点问题之一,对于软岩而言,其地基承载力的确定应通过多种测试手段。通过某第三系泥岩地区的核电项目勘察经验,分析比较了多种确定软岩地基承载力的方法。
As a classical soft rock,mudstone is easily affected by external factor such as water or long-time exposed,etc,and then its physical and mechanical properties will be changed.As an important engineering property,the determination method of bearing-capacity is one of the most important tasks.For soft rock,a variety of testing method should be adopted to confirm the bearing-capacity of foundation.In this paper,the investigation experience of a nuclear power project in Neogene mudstone area is used to analyse and compare the variety method which usually used to gain the bearing-capacity of soft rock foundation.
