Research on Permeability Regularities in Subgrade behind the Bridge Abutment
On the hypothesis of that the compacted soil was isotropic body and water movement complied with porous model of Green-Ampt, the permeability models in subgrade behind the bridge abutment with crack that is full of water were put forward by Darcy laws. In order to test the reasonableness of theoretical analysis, the flow mode test was conducted in the lab. The test results show that there is a linear relationship between horizontal length of wetting front on top of subgrade with the square root of time, in the sections at the bottom of crack, it is two time function relationship between vertical distance with horizontal length of wetting front. The test results are consistent with theoretical analysis.
