摘要
膨胀土边坡稳定问题是工程领域建设中常见的技术难题,若处理不当,可能会引起牵引式、渐进式的滑坡,严重威胁工程安全。针对引江济淮工程菜巢线分水岭段的地质条件、设计方案以及使用需求,提出了一种适用于弱膨胀土深挖方边坡的综合柔性防护方案。结果表明:该方案在充分发挥柔性防护措施优点的同时,有效地保证了边坡的安全稳定。研究成果可为边坡治理提供参考。
The stability of expansive soil slope is a common technical problem in engineering construction.If it is not handled properly,it may lead to traction and gradual landslides,which seriously threatens the safety of the proj⁃ect.Focused on the actual geological conditions,design schemes and application requirements of the watershed sec⁃tion of Caizi lake and Chao lake of the water transfer project from Yangtze River to Huaihe River,a flexible protec⁃tion scheme suitable for deep excavated slopes with weak expansive soil was proposed.The results showed that this scheme could take full advantages of flexible support structure and effectively guarantee the stability and safety of the slope.The research results could be a reference for slope treatment.
