多雨高寒地区沥青道路翻浆温度场的数值模拟

Numerical Simulation of Temperature Field of Asphalt Pavement Pumping in Rainy Alpine Regions

道路翻浆是多雨高寒地区公路建设和养护中最常见也是难以根治的一种问题.为及时发现道路翻浆并积极采取合理的防治措施,以甘南地区某公路工程为实例,通过建立路基温度场有限元模型,分析其沿深度范围内的温度场分布、温度应力和应变变化情况,为多雨高寒地区沥青道路翻浆的防治提供了参考依据.

The road pumping is a trouble most commonly encountered and extremely difficult to solve in rainy alpine regions for highway construction and maintenance.In order to discover road pumping in time and take reasonable prevention measures,a finite element model of sub-grade temperature field is established with its temperature field distribution analyzed along the scope of depth and temperature stress and strain condition.This analysis can provide some references for prevention of asphalt road pumping in rain alpine regions.
