车辆作用软土地基埋管沥青路面动力响应研究
Research on Dynamic Response of Asphalt Pavement with Buried Pipes in Soft Soil Foundation Under Vehicle Load
摘要
Abstract
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 be-tween 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 simu-lates 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.关键词
