绿色加筋格宾挡墙在尾矿库坝体加固中的应用

Application of Green Reinforced Gabion Retaining Wall in Tailings Dam Reinforcement

目前,我国共有尾矿库8000多座,总量居世界第一,其中四五等库占尾矿库总数90%以上,尾矿库大量压占土地,造成了我国土地进一步紧缺。尾矿库闭库后经土地复垦可将其作为农田、公园、工业用地和城市建设用地等,绿色加筋格宾挡墙作为新型支挡结构,具有透水性强、断面尺寸小、地基适应性强、耐久性强、造价低等特点,在保证坡体稳定的同时,有效提高土地利用效率,具有良好的生态恢复效应。该项目位于城市近郊,下游坡脚紧邻省级交通道路,尾矿库治理后即用于省级示范工业园区场地建设,对于城市土地供应紧缺的情况下,具有较高的经济效益、社会效益和生态效益。

At present,there are more than 8,000 tailings ponds in our country,ranking first in the world in total.Among them,the fourth and fifth class reservoirs account for more than 90%of the total number of tailings ponds.A large number of tailings ponds occupy land,causing further shortage of land in our country.After the tailing pond is closed,it can be reclaimed as farmland,park,industrial land and urban construction land.As a new retaining structure,the green reinforced gabion retaining wall has the characteristics of strong water permeability,small section size,strong foundation adaptability,strong durability,low cost,etc.It can effectively improve the land using efficiency while ensuring the stability of the slope body and has good ecological restoration effect.The project is located in the suburb of the city,the foot of the downstream slope is close to the provincial traffic road,and the tailings pond will be used for the construction of the provincial demonstration industrial park site after treatment,which has high economic,social and ecological benefits under the condition of shortage of urban land supply.
