摘要
目的对大连新河巷某边坡进行稳定性分析,探讨坡段的不稳定因素,提出治理措施.方法利用赤平投影原理对边坡各个坡段的稳定性进行分析,通过试验测得该边坡及断层结构面岩土体的物理力学参数,计算得到各个坡段不稳定滑面的安全系数.结果整个边坡西端AB、BC坡段是稳定的,坡面上部存在危岩,属于局部不稳定因素.边坡的主要不稳定坡段是CD、DE、EF坡段,其安全系数均小于1.25,坡段均有发生崩滑的可能.结论利用笔者提出的防护措施对大连新河巷边坡进行加固处理后,边坡达到稳定标准.
Through analysis of stability of a certain slope in Xinhe Alley, Daiian,look into the instability factors of the slope sections and propose treatment measures. Employ principle of stereographic projection to analyze the stability of each slope section, measure physical and mechanical parameters of the slope and rocksoil body of fault structural plane through experiment and calculate the safety coefficient of unstable sliding surface of each slope section. Section AB and BC of the western end of the entire slope are stable and the upper slope surfaces have unstable rocks, which are local instability factors. Main unstable slope sections are section CD,DE and EF, each with a safety coefficient lower than 1.25 and thus each with possibility of landslide. After the reinforcement treatment for the slope in Dalian Xinhe Alley through application of preventive measures proposed by the author, the slope has reached stability standard.
