Mechanics Analysis of semi-rigid subgrade pavement structure Liya Su Architecture and Civil Engineering School, Inner Mongolia University of Science and technology, Baotou, 014010, China suliya1@.imust.cn Keyword: Asphalt Pavement, Semi-rigid foundation, modulus of elasticity, reasonable thickness Abstract.
Establish the finite element model of semi-rigid pavement The pavement structure is actually a three-dimensional engineering structures, it can support any form load,so describing the road system performance of the best model is 3D model.The three-dimensional finite element model is realized in three-dimensional space within the scope of discure pavement structure and consider any distribution load form.The size of the model will not be taken to infinity in Finite element analysis, the model size will get as larger as possible, but the size is too large will greatly increase the computational effort.
