通过对小浪底库区内新安县矿区 2 75m高程淹没线以上部分居民点的环境地质分析 ,认为水库蓄水后 ,对采空区影响方式主要有水的软化作用、水压破坏、潜蚀式破坏和气爆及真空吸蚀式破坏 4种 ;并采用概率积分法、经验估算法和临界深度法预测水库蓄水后不良地质现象的发育趋势 ,重点评价蓄水后场地的稳定程度 ,并提出处理建议
Based on the environmental geologic analysis of some settlements above the inundation line of 2 75 m in Xin’an County mining area in Xiaolangdi Reservoir Area, it is considered that the main influencing modes on the goaf after water storage are water softening effect, hydraulic pressure failure and latent erosion damage And four kinds of gas explosion and vacuum ablation failure. Probability integral method, empirical estimation method and critical depth method are used to predict the development trend of unfavorable geologic phenomena after reservoir impoundment. The stability of the site after impoundment is mainly evaluated, and the treatment suggestions
