The Numerical Simulation Analysis of Pavement Slab with Cavity of Cement Concrete Pavement
摘要
Abstract
The fracture causes of cement concrete pavement and its development process and influence range are researched according to construction practice after analyzing bump at bridge-head,pavement slab with cavity and faulting of slab ends existing during operation of Nanjian-Qinzhou Section of Lanzhou-Haikou Expressway (G75) by 3D elastic and plastic FEM numerical simulation.The results show that the stress at the midpoint of the edges in three directions is changed irregularly;when the pavement slab with cavity reaches a certain state,the stress in three directions reaches the maximum.With the advancing of the analysis step,the stress finally reaches the steady state.关键词
