| 摘 要： | 京珠高速公路驻马店至信阳段 ,在建设中设计有 3 4个弃渣场。弃渣主要是弃石 ,其内摩擦角大于 45° ,按无黏性土对弃渣场边坡的稳定性进行分析表明 ,弃渣场坡角小于石渣内摩擦角即可保证渣体的稳定。其防护主要是排水处理 ,并对边坡进行削坡开级 ,对弃渣场顶面进行覆土造林。

| Abstract: | There are 34 spoil disposal areas designed during the construction of Zhumadian Xinyang section of Beijing Zhuhai Expressway. The spoils are mainly stones with inner frictional angle greater than 45°. According to the analysis of stability of the slope of spoil disposal area based on non clay condition, it shows that if the slope angle of spoil disposal area is smaller than inner frictional angle of spoils, it can ensure the spoil body stable. The protection mainly is drainage and needs building terraces on the slopes and covering soil on the top of spoils for afforestation. |
