Study on the Pore Radius of Unsaturated Soil
The stochastic and complicated pore characteristics have significant influence on engineering properties of unsaturated soil. Taking remolded red clay of Jiangxi province with different clay content as objects and taking complete soil-water characteristic fitting curves by using MATLAB software as carrier, the distribution of pores during dehydrated procedure is analyzed from micro-view of point. Based on previous achievements and large number of experimental results, the equivalent calculation method of pore radius for clay grain is proposed by using statistical theory. Taking indoor experimental results as the basis, the method of incremental step is presented and the algorithm are implemented in detail. By comparing the theoretical results of maximum capillary rise height with one-dimensional capillary experimental data, a good agreement is achieved, which is verified the proposed calculation method. As a result, the quantification of micro-structure is realized. Moreover, the proposed calculation method offers an effective method for calculating the maximum capillary rise height.
