现行的一般工程边坡勘察设计,在稳定性评价上多简化为平面问题求安全系数。常因考虑影响因素不周,计算模型和参数选择同实际不符从而严重影响评价的可靠性。小型边坡的查表法只考虑岩性,不注意分析其结构特性与弱面组合等常使误差过大。因此对岩坡稳定性判别与分析,不应局限于简单的查表或按均质模型作一般的计算。应在查明岩体结构基础上,对其可能的破坏方式和机制作出判断。根据工程作用 The current general engineering slope survey and design, more in the stability of the evaluation of simple problems for the safety factor. Often due to the impact of factors to consider the lack of calculation model and parameter selection does not match with the actual seriously affect the evaluation of the reliability. Small scale slope look-up method only consider the lithology, do not pay attention to analysis of its structural characteristics and weak face combinations often make the error is too large. Therefore, the discrimination and analysis of rock slope stability should not be limited to a simple look-up table or a general calculation according to homogeneous model. Based on the identification of the rock mass structure, the possible ways and mechanism of damage should be judged. According to the project role
