| 摘 要： | 顺层状岩质路堑边坡及其支护设计是公路和铁路路基设计难题之一 ,陡倾状顺层边坡不稳定岩体可以清掉 ,但清方量较大的缓倾角和中等倾角顺层状岩质边坡 ,其失稳破坏范围是设计人员最关心的问题。结合重庆至怀化铁路的论证设计 ,建立了顺层边坡岩体失稳破坏长度计算式 ,利用沿线自然顺层状边坡失稳破坏的调查测试资料进行对比分析 ,结果表明效果较好

| Abstract: | The design of rock bedded cutting slope and its support is one of the difficult problems in foundation design of railway and highway. The unstable rockmass on the bedrock with a high dip angle may be dug out. But it may be very expensive to dig all rockmass on the bedrock with medium and low dip angle.So the extent of unstable rockmass is of great concerned.According to the need of demonstration and design of the railway from Chongqing to Huaihua, the formulae to calculate the length of unstable rockmass of the bedrock slope were deduced. The comparison between the calculated and observed data was carried out.It shows that the results are coincident. |
