摘要

摘要: 城市快速干道的路堑边坡隐患威胁行车安全，影响城市景观，因此开展城市快速干道高陡边坡治理和生态防护研究尤为重要。以武汉森林大道高陡边坡为例，基于现场地质调查和无人机航拍等技术手段，结合研究区工程地质环境背景，分析了该高陡边坡工程地质特征，提出了支挡和生态修复的综合治理设计方案，其中支挡设计包括锚索板肋式挡土墙、锚索排桩式挡土墙、重力式挡土墙和人字形格构，生态修复设计则以厚层基材喷射技术、植生袋+挂网客土喷播绿化、绿色罩面网+爬藤植物+垂吊植物绿化以及栽植草灌植物绿化为主。实践表明，该生态防护方案提高了高陡边坡稳定性，达到预期生态复绿效果。基于此，提出多维立体综合边坡生态防护技术理念，建立城市快速干道高陡边坡生态修复评价体系。研究成果可为城市快速干道高陡边坡的工程加固和生态修复设计提供参考。

Abstract: The hidden dangers of road cuts and slopes during the construction of urban expressways seriously threaten driving safety and affect urban landscape. Therefore, it is particularly important to strengthen the research on ecological protection of high and steep slopes on urban expressways. This research takes the high and steep slope of Wuhan Forest Avenue as an example, based on on-site geological investigation and drone aerial photography technology, combined with the engineering geological environment background of the research area, analyzes the geological characteristics of the high and steep slope engineering, and proposes a comprehensive ecological governance design scheme for support and greening. The support design includes anchor plate rib retaining wall, anchor row pile retaining wall, gravity retaining wall, and herringbone grid structure. The greening design mainly includes thick layer substrate spraying technology, planting bags + hanging net soil spraying greening, green cover net + climbing plants + hanging plants greening, and planting grass and shrub plants greening. Practice has shown that this ecological protection scheme has improved the stability of steep slopes and achieved the expected ecological greening effect. Based on this, this research proposes the concept of multi-dimensional comprehensive slope ecological protection technology and establishes an ecological restoration evaluation system for high and steep slopes on urban expressways. The above research results can provide reference for the engineering reinforcement and ecological protection design of high and steep slopes on urban expressways.
