摘要开展车辆荷载作用下软土地基埋管沥青路面结构动力响应研究是岩土工程的重点课题之一。基于Fortran语言编写了Dload子程序,与现场实验进行比较,验证了Dload子程序计算的精确性。以实际工程为例分析埋管与无管沥青路面结构的差异性,并探究管道埋深、车辆载重对埋管沥青路面结构动态响应的影响。得到以下结论:(1)车辆荷载模型模拟车辆荷载作用下软土地基埋管沥青路面结构的动态响应是准确可靠的。(2)在交通荷载反复作用下埋管路面结构处更易破损毁坏。(3)车辆载重和管道埋深均对沥青路面结构有显著的影响,在道路使用过程中应严格控制车辆载重,严禁超载;有埋地管道穿越路基时应控制管道埋深在2.0 m以上。 One of the key topics in geotechnical engineering is the study of the dynamic response of asphalt pavement structures with buried pipes in soft soil foundation under vehicle loads.A Fortran-based subroutine,Dload,was developed and validated for computational accuracy through compari-sons with field experiments.An actual engineering case was analyzed to contrast the differences between asphalt pavement structures with and without buried pipes,and to investigate the influence of pipe burial depth and vehicle load on the dynamic response of buried pipe asphalt pavement structures.The conclusions are as follows:(1)The vehicle load model accurately and reliably simulates the dynamic response of asphalt pavement structures with buried pipes on soft soil foundations under vehicle loads.(2)Pavement structures with buried pipes are more prone to damage under repeated traffic loads.(3)Both vehicle load and pipe burial depth have significant impacts on the asphalt pavement structure.During road operation,vehicle load must be strictly controlled to prevent overloading.When buried pipelines traverse the roadbed,the burial depth should be controlled to be above 2.0 m.
