针对膨胀土的特性和病害形成机理,根据现场具体情 况,在总结相关设计和实践经验的基础上,采取“保湿防渗、加 强排水、及时施工”的原则,对路基基床、边坡及坡脚等部位采 取了有针对性的措施,特别是采用“重塑土反压”的边坡防护与 加固措施,保证了朔黄铁路膨胀土路基稳定与安全。
Effective measures were adopted to ensure the reliability and safety of subgrade of ShuoHuang Railway which is located at swelling soil area. Seepage control and drainage were enhanced for slope protection and strengthening.
