摘要
基于西北季节性冻土地区某运营中高速铁路地下水路堑冻害治理的设计实例,介绍了地下水路堑的冻害情况,研究了其常规治理措施及存在的问题,探讨了治理措施优化方案,比较了边坡形式优化前后的经济效益。结果表明,优化治理措施后,减少了土石方开挖,降低了工程投资,缩短了施工周期,具有良好的经济技术效益。
Based on a design case of frost damage control for a groundwater cutting in an operational high-speed railway in the seasonal permafrost region of Northwest China,this study examines the frost damage conditions of the groundwater cutting,evaluates conventional control measures and their limitations,explores optimized control strategies,and compares the economic benefits before and after slope optimization.The findings indicate that optimizing the control measures has reduced earthwork excavation,lowered project costs,shortened construction time,and demonstrated significant economic and technical benefits.
