摘要
为解决城乡建设用地扩张过程中高陡边坡稳定性不足导致水土流失加剧问题,以某城乡建设用地扩张项目为研究对象,针对性提出“坡率优化+锚杆格构梁支护+立体排水系统”方案,同步配套“工程措施+植物措施+临时措施”水土保持方案。监测结果表明,优化后边坡的安全系数提升至1.35,年均水土流失量降至7.2 t/hm^(2),植被覆盖度6个月内达85%以上。
In order to solve the problem of accelerated soil erosion and water loss caused by insufficient stability of high and steep slopes in the process of urban and rural construction land expansion,taking an urban and rural construction land expansion project as the research object,this paper proposes a targeted scheme of"slope ratio optimization+bolt-latticed girder support+threedimensional drainage system",complemented by a soil and water conservation scheme of"engineering measures+vegetation measures+temporary measures"at the same time.The monitoring results show that the safety factor of the optimized slopes is increased to 1.35,the average annual soil erosion and water loss is reduced to 7.2 t/hm2,and the vegetation coverage exceeds 85%within 6 months.
