摘要
以某高速公路项目为例,采用数值模拟手段,分析不同路基回弹模量工况条件下,道路表面弯沉值与路基压应变的变化情况。研究表明,在相同路基回弹模量的情况下,道路表面的弯沉值随着半面层、刚性基层和基础模量的增加均呈现近线性减小,而路基压应变则侧非线性减小。
Taking expressway project as an example,the changes of road surface deflection and subgrade compressive strain under different subgrade resilience modulus conditions are analyzed by numerical simulation.The research shows that under the same subgrade resilience modulus,the deflection value of road surface decreases nearly linearly with the increase of half surface layer,rigid base and foundation modulus,while the compressive strain of subgrade decreases nonlinearly.
