Analysis of Cement Concrete Pavement on Steep Slopes and Sharp Turns Section Based on ANSYS

Rural road in mountain area often has small radius and great longitudinal.How to avoid the adv-ance damage of concrete pavement of rural roads in mountain area in order to ensure the service life and reduce the maintenance costs of rural roads has become an important subject of rural road construction.This paper uses three-dimensional dynamic finite element to analyze and calculate the maximum tensile stress and maximum shear stress at the bottom of slab of the section consisting of small radius and steep slope.Comparing it with cor-responding state of beeline road and gentle slope,the mechanical response characteristics of the pavement of section with steep slope and sharp turns are obtained.
