摘要
通过对运营多年的旧路路基在不同季节、不同层位进行含水量现场测试,根据区域内温度、降雨量的年变化情况及地下水位分布状况,并结合路基不同层位含水量一年内的变化情况,分析路基含水量随温度、降雨量、地下水位周期性变化的规律以及路基中水分的分布状况、稳定后的湿度状态,并总结提出旧路路基湿度周期性变化规律及影响因素。
Through on-site testing of water content of different layers in different seasons of the old roadbed for many years, according to the annual change of temperature and rainfall in the region and the distribution of the water table, combined with the change of water content of different layers of the roadbed within one year, in the paper the law of the periodic change of water content of the roadbed with temperature, rainfall and groundwater level, as well as the distribution of moisture in the roadbed, the stable humidity state are analyzed, and the periodic changes and influencing factors of the old roadbed are concluded and put forward.
