构建长期野外观测研究体系,解密黄土路基全寿命周期性能

作者:金沙js55555官网科技评价中心 发布时间:2018/5/22 下午2:09:41 查看次数:4692

    我国黄土分布广泛,总面积达64万平方公里。黄土具有显著的结构性和强烈的水敏性,作为公路路基填料时,表现出湿陷性、易溶蚀、易冲刷、难压实等工程特性,易引起道路地基承载力不足、沉降过大、稳定性不足、大面积沉陷等问题。同时山西省作为产煤大省,煤炭贸易量大,传统的轻型交通已转变为重载交通甚至特重交通,传统的路基设计施工规范及方法已不能完全满足重载交通的需求,亟待研发或提出一套适合于重载交通作用下黄土路基的设计施工新技术。
    山西省交通科学研究院依托交通运输部建设科技项目“重载交通作用下黄土路基全寿命周期性能研究”,历时三年,开展了重载作用下黄土路基全寿命周期性能的系统研究,建立了基于增湿剪位移的结构性黄土本构模型,提出了重载作用下黄土路基工作区影响深度,建立了路基压实的孔隙率控制标准,给出了不同湿陷性黄土地基处理技术,构建了黄土路基长期性能自动化远程监测平台,提出了在役黄土路基病害探测定位技术,形成了黄土路基养护辅助决策体系。
    本项目获发明专利5项,软件著作权3项,发表论文16篇,出版专著1部,主编地方标准1部。项目成果在山西、宁夏、陕西、甘肃等高等级公路中得到成功应用,对提高黄土地区重载公路的修筑技术水平和运营管理,完善国家中西部地区交通基础设施网络,促进区域经济社会融合,服务“一带一路”国家战略,保障国家安全,具有重要的理论和现实意义。
