大型采石废弃地弃渣边坡稳定技术设计研究

近年来,采石场大面积弃渣边坡无防护堆积和坡面水土流失等问题严重.文章基于"蓄水范式"理念,以山阴县小娘娘山采石场为例,采用理论研究与实用施工技术相结合的方法,提出一套因地制宜的弃渣边坡稳定技术,该技术包括蓄水稳定技术设计和配套措施设计,以研究区内的一处弃渣边坡为示范点进行了实际设计和施工.结果表明,弃渣边坡稳定技术能有效提高弃渣边坡的稳定性和蓄水能力,施工方便、成本低,在实际工程中具有广泛地推广性.

Research on Stabilization Technology of Quarry Slopes in Large-Scale Quarries

In recent years, the ecological problems of quarries have become increasingly prominent.The most serious problem are the large area accumulation of quarry slopes and soil and water loss on the slope.In order to ensure the stability of quarry slopes and to promote the ecological restoration of slopes, the study took a large abandoned quarry of Mt.Xiaoniangniang in Shanyin county as an example, using the method combining the theoretical research with practical construction technology to design the method based on "Water Storage Paradigm".The quarry slopes stabilization technology included the design of water storage stabilization technology and supporting measures.We took a quarry slope in the study area as a demonstration point, which shape was artificially changed into a water collection slope(slope length<15 m) and an interception slope(2.5 m wide), then combining with the supporting measures which included loess-breakstone mixture(mix proportion 9:1) matrix improved technology and a design of rocky drainage, torrent gutter and reservoir flood control system, specific practical design and construction were carried out in Mt.Xiaoniangniang.The research shows the quarry slopes stabilization technology can effectively improve the stability and water storage capacity of quarry slopes, which further reduce soil and water loss and provide favorable conditions for vegetation recovery in the future.What's more, easy construction and low cost make it can be widely spread in the practical engineering.
