摘要
该文针对软土地区城市道路地下管道对于沥青路面的不利影响进行分析,采用有限元方法分析了管道周边和上部土基的模量对于沥青面层内部剪应力的影响,并与容许剪切强度进行了对比。提出必须采取合理措施增加管道周边的土基强度,从而有效地避免沥青路面的剪切破坏。
The article analyzes the disadvantage influence of the underground pipelines of the urban roads in the soft soil area on the asphalt pavement,uses the finite element method to analyzes the influence of the surrounding and upper soil base modulus of the pipelines on inner shear stress of asphalt surface,compares it with the allowed shear strength,and puts forward the reasonable measures necessary to take for strengthening the soil base strength surrounding the pipelines so as efficiently to avoid the shear damage of asphalt pavement.
