    Optimization of Treatment Technology for Landslide in Yinwan Dump of Heidaigou Open-pit Mine

    • 摘要: 受基底赋存水、软弱层及排弃增高等因素的影响,阴湾排土场西帮发生了变形。为避免变形加剧导致滑坡,需采取合理的防治措施。依据现场工程地质条件,设计了抗滑桩和排土压脚2种滑坡治理方案。抗滑桩方案根据排土场边坡可能发生的滑坡模式,设计了抗滑桩参数,可快速增加滑体抗滑力。排土压脚方案通过增加边坡下部岩土体自重,提高了滑坡整体稳定性,并进行了压脚区的防排水设计。结合现场情况,通过可行性及经济分析对方案进行对比,最终选取了排土压脚方案。

       

      Abstract: Affected by the water in the base, weak layers, the increase of the slope and other factors, deformation at western slope of Yinwan dump had occurred. It is necessary to take reasonable control measures to avoid the occurrence of the landslide caused by the increase of deformation. According to the site engineering geological conditions, two kinds of landslide control schemes are designed. In the anti-slide pile scheme, parameters were designed based on the probable landslide model, which could quickly increase the anti-sliding force of the sliding body. Earth presser foot scheme would improve the whole stability of the landslide by increasing the weight of the rock and soil mass in the lower part of the slope and the waterproof and drainage in the foot area is designed. Through the feasibility and economic analysis of the program, the soil presser foot program is better combined with the field situation.
