【摘要】 从膨胀土湿胀干裂和强度衰减的工程特性出发,提出了膨胀土地区排水设计原则,介绍了膨胀土地区防排水主要技术措施。并以我国南方某公路两段路堑边坡防排水优化设计为例,说明排水和保湿防渗在膨胀土(岩)边坡稳定性方面所取的重要作用。更多还原

【Abstract】 Based on the expansive soil’s engineering characters of wet swelling and season check and strength attenuation,this paper put forwarded the principle of drain design in expansive soil areas,discussed the main technology measures of water-proof and drain in expansive soil areas.Also,this paple provided two sections cutting slopes’ optimized water-proof and drain design as examples to discussed the drain and moisture?-retaining and impervious have a very important meaning in slope stability.更多还原
