摘要
黄土和黄土状土在我国的分布面积较为广泛,约占64万km2左右,其中,约有3/4的黄土属于湿陷性黄土。随着我国黄土地区工程建设项目的逐渐增加,黄土边坡部位所发生的滑坡、崩塌等失稳性破坏问题的发生率也呈现出了明显的上升趋势,并对道路的正常应用以及工程施工质量造成了较为严重的不良影响。因此,在工程施工前对黄土边坡的抗剪强度进行分析和取值,对于提高工程施工质量具有十分重要的作用。本文对黄土边坡勘察中抗剪强度的影响因素进行了分析,并探讨了黄土边坡稳定性计算的取值方法。
Loess and loess-like soil in our distribution area more widely, accounting for about 640,000 km2, of which, about 3/4 of the loess is collapsible loess. With the gradual increase of China＇s loess areas of construction projects, the the loess slope positions such as landslides, avalanches occur instability destruction incidence also shows a clear upward trend, and normal road applications as well as the quality of construction cause serious adverse effects. Therefore, before the construction of the shear strength of loess slope analysis and value, has a very important role in improving the quality of construction. This paper analyzes the factors on the shear strength of loess slope survey and value of loess slope stability calculations.
