摘要
首先介绍了1991年10月29日,发生在平朔安太堡露天煤矿南排土场大规模滑坡的基本情况,分析了这次滑坡的原因及性质,接着通过对滑面抗剪强度的反算,获得了较为精确可靠的摩擦强度参数,从而对滑坡体在滑前与滑后的稳定性进行了研究。在此基础上,提出了以提高排土场稳定性为目的,以工程及生物措施为手段。
First, it is introduced that the large landslide on the south dump of Antaibao surface mine in Pingshuo on Oct. 29, 1991, and the cause and quality of landslide are analyzed, then, through the calculation of anti shear strength in an opposite direction on the slideface, the accurate data of the anti shear strength are obtained, and the stability of the landslide before and after sliding are discussed. On the basis of these, it is suggested that the new ideas of integral control the slope, which is to improve the dumps stability by engineering and biological measures.
