Paper Title:
Test of Expansive Soil Roadbed Improving with Fiber Materials and Numerical Simulation Analysis
  Abstract

Based on the characteristics of expansive soil and polyethylene fibers used and researched, relevant data of fiber improving expansive soil are obtained by laboratory soil tests, and the numerical simulation parameters are derived by some formulas, through the useing of Mohr-Coulomb and elasticity constitutive model of the geotechnical professional software FLAC3D, we simulate the effect of polyethylene fibers improving expansive soil. Results of laboratory tests show that polyethylene fibers have visual effects on the compressibility and compression modulus of expansive soil ; Numerical simulation shows that the polyethylene fiber soil of expansive soil can reduce the settlement and horizontal displacement of roadbed of expansive soil significantly. Both of them show that fiber materials have high value of the promotion and application in engineering.
