摘　　要：渣土受纳场边坡稳定性问题是城市建设快速发展过程中面临的亟待研究的科学问题。本文以深圳市某余泥渣土受纳场边坡为研究对象,基于极限平衡方法,对在渣土边坡底面的不同位置及设置不同宽度平台时的稳定性系数进行对比研究,并找到设置平台的最优位置。结果表明:设置平台的最优位置为坡底面的中点处;当设置的平台宽度大于0.91m时,平台设置在中部,边坡的安全储备最高;当设置的平台宽度在0.53~0.8m时,平台只能设置在中部;当设置的平台宽度小于0.53m时,边坡的稳定性系数小于安全系数。该研究成果对完善有关渣土方面的规范具有一定的参考价值。The slope stability of construction solid waste landfill slopes is a scientific problem that needs to be studied urgently under the rapid development of urban construction. A case study of a construction solid waste landfill slope in Shenzhen is carried out. Based on the stability coefficients of the slope obtained by limit equilibrium method,the optimal place of the platform is located. The results show that the optimal position of the platform is the midpoint of the bottom. The stability coefficient reaches maximum when the platform width is greater than 0. 91 m and the platform is set at the middle of the bottom surface; when the platform＇s width is between 0. 53 m and 0. 8 m,it can only be set at the middle of the slope bottom;however,when the platform width is less than 0. 53 m,the stability coefficient is less than the required safety factor. The achievements could be referred by the construction solid waste landfill slopes.
