Paper Title:
Study on the Permeability of Reinforced Soil with Herb Fiber under Different Salt Solution Concentration
  Abstract

The best is to read these instructions and follow the outline of this text. n this investigation, laboratory permeability tests were conducted on the wet-processing reinforcement specimens to study the feasibility of reinforced soil as a material of construction. Two kinds of reinforced specimens with different reinforcement materials (wheat straw (C) and flax (M)) were mixed with 3% contents of soil mass, and product to the cylindroid for measurement of permeability by a flexible-wall permeameter. The variation relationship between permeability coefficient and Na2SO4 concentrations was analyzed. Test results show that the liquidity reduced with incrassate diffusion layer caused by the increasing Na+ concentrations in the diffusion layer of soil particles, and then a decrease of permeability is found. With the increasing time of permeability, it is found that the permeability coefficient decreased due to the consolidation and decreasing porosity of specimens caused by the change of stress state. At the same time, ion exchange adsorption and water film incrassate occurs in soil particle surface which also benefit to the decrease of permeability coefficient.
