内陆河湖相软弱地基处理方法研究

针对我国内陆河湖相软弱地基处理中广泛采用滨海软土地基的处理方法,没有重视内陆河湖相软弱地基工程性质与滨海软土地基工程性质的差异(分布厚度、分布规律、物理力学特性等不同),处理方案缺乏针对性,投入大而收效差的现状,在分析了内陆河湖相软弱地基工程地质特征的基础上,将内陆河湖相软弱地基划分为薄硬壳层地基、厚硬壳层地基、夹层型地基三种典型地质结构形式,并针对不同的地质结构提出了适宜内陆河湖相软弱地基的处理方法。

Research on the Technology for Soft Foundation Treatment in the Area of Inland River-lake Facies

t present, for the soft foundation treatment in the area of inland river-lake facies in our country, the coastal soft soil foundation treatment method is widely adopted. As the difference between engineering properties of soft foundation in the area of inland river-lake facies and coastal soft soil foundation (different distribution thicknesses, distribution rules, physical and mechanical properties, etc.) receives less attention, the treatment plan is not targeted, resulting in high investment but low yield. On the basis of analyzing engineering properties of soft foundation in the area of inland river-lake facies, the soft foundation in the area of inland river-lake facies is divided into three typical geological structures: thin duricrust foundation, thick duricrust foundation and interlayer foundation. Treatment methods suitable for soft foundation in the area of inland river-lake facies are put forward according to different geological structure.
