摘要
高速公路中红砂岩切方边坡失稳普遍存在。通过对两条高速公路边坡的调查研究和整治设计可以看出,边坡失稳主要与砂岩层面顺坡向、风化及节理发育程度有关外,还与地表形态、地表水下渗条件等密切有关。分析这些因素,为以后类似边坡工程积累经验,减少边坡开挖造成滑坡,对从事类似工程的设计施工,监理人员有参考作用。
Red sandstone landslides are widely existed in expressways. Investigation and treatment of landslides in two expressways are summarized. By the following research, we can see that the instability of slope is highly correlated not only with the along-slope of sandstone-layer, weathering and developing level of joint, but also with the surface pattern of earth and the penetrating condition of surface water. Experiences are accumulated to apply to the similar projects and reduce the landslide result from slope excavation through the summary and analysis. At the same time, it might be used as reference for the personnel who design, construct or supervise the similar projects.
