The paper develops an analytical model based on the force equilibrium for the design of steep slope geosynthetic liner systems to overcome downdrag loads from waste settlement. This analytical model calculates the required tensile stiffness for a high strength/stiffness geotextile (HS-GTX) reinforcement over the GMB to limit the maximum HS-GTX tensile strain to 5% and the maximum GMB strain to 4% on the side slope. The numerical model illustrates the need for reducing the GMB tensile strains for a single GMB liner on a steep landfill slope and confirms that the use of a HS-GTX over the GMB is able to limit the maximum HS-GTX and GMB tensile strains to the acceptable strain levels. The analytical model developed in this paper is a practical tool for preliminary design to limit tensile strains of the HS-GTX and GMB in a steep slope geosynthetic liner system.

本文开发了一种基于力平衡的分析模型，用于设计陡坡土工合成衬垫系统，以克服废物沉降产生的向下阻力。该分析模型计算 GMB 上高强度/刚度土工织物 (HS-GTX) 加固所需的拉伸刚度，以将边坡上的最大 HS-GTX 拉伸应变限制为 5%，将最大 GMB 应变限制为 4%。数值模型说明了在陡峭的垃圾填埋场斜坡上需要减少单个 GMB 衬垫的 GMB 拉伸应变，并证实在 GMB 上使用 HS-GTX 能够将最大 HS-GTX 和 GMB 拉伸应变限制在可接受的应变水平。本文开发的分析模型是初步设计的实用工具，用于限制陡坡土工合成衬垫系统中 HS-GTX 和 GMB 的拉伸应变。
