复合土堤在填土高边坡中的运用及设计方法

Application of Composite Earth Embankment in Filling High Slope and Design Method

本文介绍广州某32m高填土边坡,采用重力式挡墙结合复合土堤的支护方案,即在边坡中设置土工格栅、格构梁结合锚定板满足了高填土边坡的安全稳定性。采用三维数值模拟方法与传统计算和实际监测数据进行分析,实际监测数据表明边坡最大水平位移和沉降位于坡顶挡墙位置处,分别为16.23mm和10.2mm,模拟结果与现场监测结果基本一致。本项目中复合土堤在填土边坡设计方法的成功运用,可为类似工程提供参考和借鉴。

This article introduces a 32m high fill slope in Guangzhou,which adopts a gravity retaining wall combined with a composite earth embankment to support the plan.That is,the geogrid,lattice beam and anchor plate are set in the slope to meet the requirements of the high fill slope.Security and stability.Using three-dimensional numerical simulation method and traditional calculation and actual monitoring data to analyze,the actual monitoring data shows that the maximum horizontal displacement and settlement of the slope are located at the top of the slope retaining wall,which are 16.23mm and 10.2mm,respectively.The simulation results are basically consistent with the on-site monitoring results.The successful application of the composite earth embankment in the design method of the fill slope in this project can provide reference and reference for similar projects.
