摘要
针对某市固体废物垃圾填埋场,应用SLOPE/W极限平衡分析程序对垃圾堆体坡角、渗沥液水位、衬垫系统界面强度和库区边坡锚固平台长度等因素对填埋体边坡稳定性的影响进行了分析,结果显示:垃圾堆体的潜在滑动面经过底部衬垫层;衬垫系统的界面强度、堆体坡度和渗沥液水位对填埋体边坡的稳定均有显著影响;锚固平台长度对堆体稳定性的影响有限。在参数影响性分析的基础上,针对该填埋场提出了控制措施和方法。
Take a solid waste landfill site as an example, SLOPE/W software based on limit equilibrium method was used to analysis the influence of slope of waste pile, water level of waste leaehate, interface strength within the liner system, and length of anchoring platform on the slope stability of the landfill. The results showed that the potential slip surface of waste pile passed the bottom liner layer. The interface strength with liner system, slope of waste pile, and water level of waste leaehate had outstanding effect on the stability. The length of anchoring platform had little effect on the stability. According to the influence analysis of parameters, some treatment measures and methods were proposed.
