ENGINEERING CHARACTERISTICS AND START-UP MECHANISM OF SLAG CLASTIC FLOW IN ZHAOCHUAN DISTRICT, XUANHUA

  • 摘要: 张家口宣化地区存在大量具有潜在危险的松散矿渣堆积体,文章以该地区具有代表性的响水沟松散矿渣堆积体为研究对象,对矿渣的颗粒组成、矿物成分、力学性质等进行详细的室内试验研究,结果表明:矿渣堆积体属砾质砂土,粘粒含量少,且级配不良,松散易流动。同一干密度下,随含水率增加,矿渣抗剪强度先增大后减小,当含水率为15%时,其粘聚力最低,表明响水沟矿渣堆积体失稳启动下滑的界限含水率可能在15%左右。综合以上分析结果,拟合得到粘聚力与含水率关系公式,初步预测矿渣碎屑流启动下滑的临界含水率。这一认识对该区矿渣堆积体的稳定性评价及碎屑流灾害预警有重要意义。
