水泥处治软土的三轴应力应变特性研究

Study on Triaxial Stress-Strain Characteristics of Cement Treated Soft Soil

利用水泥作为固化剂,通过搅拌机械在地基深处将软土和固化剂强制搅拌的处治方法在当今工程建设中已得到广泛使用。但对于不同土质,水泥固化效果有所不同,如利用水泥处治含高含水率、富含有机质的软弱土层时,往往出现固化土强度偏低的现象。所以,本文以福建沿海某工地的软土为样本,讨论研究水泥掺量对固化土应力应变特性的影响。

Using cement as solidifying agent, the treatment method of forced mixing of soft soil and solidifying agent in deep foundation by mixing machine has been widely used in today’s engineering construction. But for different soil, the effect of cement solidification is different. For example, when using cement to treat soft soil with high water content and rich organic matter, the phenomenon of low strength of solidified soil often appears. Therefore, taking the soft soil of a construction site in Fujian coast as a sample, this paper discusses and studies the influence of cement content on the stress-strain characteristics of solidified soil.
