摘要
通过试验路观测及室内外试验研究,路基的稳定性主要取决于土、水、温度,其中水是根源。路面垫层改设隔离层下移到路基范围内使路基由潮湿状态转为干燥状态,保证土基受力工作区深度范围内的路基稳定性。
According to the observation in trail-section indoor and outdoor, the subgrade stability is determined by soil nature, water and temperature, among which water is the sticking point. The insulating course changed from pavement bedding course is set down to the subgrade range so that subgrade is changed from dampy state to dry state by ensuring the stability of subgrade under the load.
