摘要
简述了3种基于极限平衡理论分析边坡稳定性分析的方法,利用SLOPE/W程序对延安西市路西沟凤凰山滑坡进行了稳定性分析。建立了各级滑坡的计算模型,得出了分别采用Bishop法和Jan-bu法在未考虑地下水和考虑地下水的两种情况下各级边坡的安全系数。将SLOPE/W程序分析结果和剩余下滑力法计算结果进行比较分析,表明应用SLOPE/W程序进行土质边坡稳定性分析有较大的工程意义。另外,SLOPE/W程序模拟结果表明,水是影响边坡稳定的关键因素。
Three slope analysis methods using limit equilibrium theory are introduced, then combining with real project of Fenghuang Mountain slope at Xishi Road in Yan＇an, the stability of the slope is analyzed with SLOPE/W program. The analysis model is founded, and the safety factor of each step slope is calculated separately by means of Bishop and Janbu methods under the conditions without underground water and with underground water. The comparison between the computer stimulating resuits and the results calculated by means of surplus thrust force is made, which indicates that the stability analysis of soil slope with SLOPE/W program is reliable and that water is a key factor to slope stability.
