| 本文选择大连市中山区长利巷地区的边坡，通过现场采取岩土样，进行室内试验得出各地层力学物理参数，对边坡进行稳定性分析。本文针对目前所拥有的模拟软件与方法，分析并筛选出适合该边坡的模拟软件。利用Geo-Studio软件建模、模拟，使用Morgenstern-Price方法进行计算，通过分析得到计算结果，该边坡的安全安全系数为1.127，因此认为其属于不稳定边坡。对于不稳定边坡，本文对主流的边坡支护方法进行分析筛选，拟采用扶壁式挡土墙支护方案对其进行预防。根据规范设计挡土墙尺寸，并对该挡土墙进行抗倾覆抗滑移验算，得出的验算安全系数满足规范要求，由此可得知该支护方案方法合理，技术可行。 |

| This paper presented ananalysis on the stability of a slope located in the Changli Lane, Zhongshan district,Dalian city. To analyse slope stability,the physical parameters of soil and rock at this slope were determined by laboratory experiments on the samples collected from the site. From the software available at present,Geo-Studio was chosen to conduct modeling of this slope. And the Morgenstern - Price method was used to calculate its stability. Results show that the safety factor of the slope is 0.994, indicating unstable and a support measure must be taken at this place. This work suggested to adopt the scheme of the counterfort retaining wall to protect the slope. According to the code of retaining walls, we have designed the size of this wall and checkedits anti-overturn and anti-slip by calculation. The resultant safety coefficient meets the requirements of the specification, proving that the scheme of the support system proposed is reasonable and feasible. |
