A BRIEF DISCUSSION ON PROPERTIES OF SWELL SOIL AND STABILITY OF FOUNDATION IN DANGYANG-YICHANG SPEEDWAY
-
摘要: 当宜高速公路沿线存在有大量膨胀土, 为使其加固方案合理, 避免滑坡、塌方等现象的发生, 结合当宜高速公路膨胀土试验研究及稳定性分析, 对沿线膨胀土性质与路基稳定问题进行了分析探讨, 并提出了有针对性的处治方案.Abstract: Based on the situation of large-scale distribution of swell soil along Dangyang-Yichang speedway, the paper presents the studies on the swelling soil test and stability analysis. In order to optimize the reinforcement measures, to avoid slope movement, rock-fall as well, it further discusses the properties of swell soil and the stability of foundation so as to find the remedial measures.
