摘要
预应力锚索在岩土工程边坡已经得到了广泛地应用,但在露天煤矿边坡的应用还不多见。本文介绍了预应力锚索加固在露天煤矿非工作帮的应用实例,就不同条件及不同加固参数的边坡加固效果进行了研究。其结果表明,通过预应力加固的边坡,其稳定性得到迅速提高。实施的加固参数能够满足矿山边坡的稳定要求。加固技术已在该矿得到应用。
Pre-stressing cable has rarely been used in supporting mining slopes even though it has been widely applied in geotechnical slope projects. This paper presents an engineering example for the application of pre-stressing cable in supporting excavated slope in the west open-pit of the Pingzhuang coalmine. Slope stability analyses are conducted under different geological conditions and supporting parameters. The results indicate that the stability of the slope is increased with the pre-stressed cable, and reinforcing parameters satisfy the requirements for safe operations. The technique has been adopted to enhance the slope stability in the mine.
