| 摘 要： | 膨胀土滑坡问题在工程建设领域出现的越来越多,准确地了解膨胀土土体各项参数对其稳定性有何影响显得尤为重要。以宿州至扬州高速公路天长段膨胀土边坡实例为计算模型,利用正交试验探讨了边坡土体天然密度、粘聚力、内摩擦角、弹性模量和泊松比对其稳定性的影响,得出了一些有意义的结论,为工程建设中膨胀土边坡设计和治理提供参考。

| Abstract: | Expansive soil landslide problems appear more and more in the field of construction engineering.It is particularly important to correctly understand what influence of the expansive soil parameters is on its stability.Taking an expansive soil slope in Tianchang Section of Suzhou-Yangzhou Expressway as a calculation model,this paper discusses the influences of natural density,cohesive force,internal friction angle,elastic modulus and poisson ratio of slope soil on its stability by using the orthogonal experiment and gives some significant conclusions,which provides the references for the design and treatment of expansive soil slope in engineering construction. |
