| 摘 要： | 中国南方花岗岩及其类土质分布广泛。随着高速公路的发展,花岗岩类土质高边坡越来越多,有的类土质边坡高度超过80 m。类土质边坡稳定性如何?采用什么模型和计算方法?计算参数如何选择?这些问题都没有定论。在边坡设计中工程师多凭经验。在详细调查已有花岗岩类土质高边坡的基础上,从稳定性的角度划分了我国南方花岗岩类土质边坡的结构类型,研究了类土质边坡岩体滑动的力学模型及参数选择,对汕揭高速公路k53+760～k54+022类土质高边坡的稳定性进行了详细分析。

| Abstract: | Granite and its soil are widely dispersed over the southern part of China.There have been more and more granite soil high slopes along with the development of highways.The height of some slopes is more than 80 m.How is the stability of high slopes of the similar soil? Which model and method can be used? How to select the calculation parameters? No final conclusion has been reached on those questions.The engineers mostly rely on the experience in the design of slopes.On the basis of researches on the granite soil high slope,the structural types of granite slopes in south China are studied.The failure types of granite soil slopes are discussed.The mechanical models and the selection of the parameters of slope slide are studied.An analysis of the high slope stability of Shantou-Jieyang Expressway k53+760～k54+022 is given. |
