摘要
研究边坡安全系数与各影响因素之间的变化关系,找出主要因素,对于边坡治理的设计和施工具有一定的参考价值.根据铅厂沟滑坡的地质条件,分析了C,φ值,库区水位Zw,地震加速度a,地下水位Gw等5个因子对边坡稳定的影响程度.结果显示:其程度由大到小为a>Gw>φ>Zw>C.因此,在滑坡治理和维护过程中,应该优先考虑a和Gw的影响.
Slope stability is often determined by multi-factor. By studying the relation between safe coefficients and each variety of the influence factors, then the main factor is found out, which provides the reference for slope reinforcement in the process of design and construction. According to the geology condition of Qianehanggou slope,the influence degree to the slope stability of five factors such as C, ψ value,the reservoir level Z ,earthquake acceleration a and groundwater level G, are analyzed. The result shows the influence degree is a 〉 Gw 〉 ψ 〉 Zw 〉 C. Therefore,much more attention should be paid to the most important factors such as local earthquake and groundwater firstly during the process of slope harnessing and defending.
