Basal synthem is the Taishan mountain group in archaean, is mainly the gneiss; The paleozoic synthem besides the regional lost stratas: Upper Ordovician, Silurian-Devonian and Lower Carboniferous, other stratas have the distribution, divides into Cambro-ordovician and Permo-Carboniferous two structure subgroups. Cambro-ordovician is a set of carbonate construction, Permo-Carboniferous system is a set contains the coal clastic rock deposition; In the mesozoic synthem lost Upper Triassic and Upper Crataceous ,growth Middle-Lower Triassic and Middle-Lower Jurassic and Lower Crataceous three structure subgroups, main growth varicolored land facies clastic rock, discovered rich fossil data such as cryptogam ,Ostracoda and Chareae and so on.

Detailed studies are made as follows: Searching the key internal factors which can affects slope stability. According to the geological data which was gained by exploration investigation, establishing a geological model which can reflect rock mass characteristics;With analyzing the internal and exterior factors synthetically, the deformation and possible failure mechanism and mode of the cut slopes was confirmed which combines with stereoic projection and other techniques;The stabilities of the 14 high slopes are estimated synthetically by applicable design codes and guidelines. With the estimate result and some other analysis methods, the rock mass mechanical parameters of slope are identified;As a results, 14 high slopes fall into 4 categories based on rockmass characteristics and discontinuities. The stability and deformation of some typical slopes was analyzed with distinct element method by UDEC;The safety factor of some dangerous slopes are calculated by rigid limiting equilibrium method for coMParison.

首先着重研究影响边坡稳定性的内在因素，主要是通过地质勘探、测量、现场观测等手段取得研究区地质体的基础地质资料，建立起能够反映地质体结构特征的地质模型；随后综合分析潜在的内外部影响因素，并结合赤平投影对边坡可能的失稳模式或破坏机制作出判断；运用已有岩体质量分类方法对沿线14个高陡边坡稳定性进行初步的评价，并结合试验研究、经验判断、工程类比等手段确定了坡体的岩体力学参数；根据稳定性初步评价结果将研究区14个高陡边坡按开挖方式分为4大类，并利用离散元程序UDEC对各类典型高陡边坡进行了稳定性计算分析；对潜在危险边坡利用刚体极限平衡法求出了不同工况下的安全系数。
