| 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. |
