福州滨海软土的物理力学特性试验研究

对福州可门港原状软土进行一维固结压缩和界限含水率试验。得到了福州地区滨海软土由弹性状态向塑性状态变化过程中其固结屈服应力、压缩模量、液限、塑限与土层深度的关系,对试验结果进行分析可知,福州软土的固结屈服应力随着土层深度的增加而增加,不同深度的土样,其固结屈服压力和有效上覆压力相差不大,超固结比OCR在1附近,但土样的压缩模量、液限、塑限与土层深度关系不大。

One-dimensional consolidation compression and limited water content tests of undisturbed soft soil in Fuzhou KemenPort were carried out. The relationship between the consolidation yield stress, modulus of compression, liquid limit, plastic limit and thedepth of soil layer in the process of changing from elastic state to plastic state of coastal soft soil in Fuzhou area is obtained. The consolidation yield stress of Fuzhou soft soil increases with the increase of soil depth. There is little difference between the consolidationyield pressure and effective overburden pressure of soil samples with different depth. The over-consolidation ratio OCR is about 1. However, the modulus of compression, liquid limit and plastic limit of soil samples have little to do with the depth of soil layer.
