重塑黏土毛细上升高度研究
Study on Height of Capillary Rise for Remolded Clay
摘要
Abstract
The complexity of pores in unsaturated soil is the most direct factor affecting the capillary. The soil-water characteristic test and the vertical one-dimensional capillary test of the clay samples with different clay contents were used to fit the van Genuchten model by way of MATLAB, and the complete soil water characteris-tic curve was obtained. Based on pores of the soil structure, the calculation formula of equivalent aperture about clay particles was gained after summarizing experimental results. On the basis of the above, the maximum height of capillary rise of unsaturated soil was estimated, which proved to be rational and feasible by results of vertical one-dimensional capillary test. This estimation of capillary rise height can provide reference for the treatment of the subgrade diseases caused by capillary.关键词
