【摘要】 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 ,并提出处理建议更多还原

【Abstract】 This paper analyzes the environmental geology of inhabitant site at Xinan diggings over submerge line (EL275 m) in Xiaolangdi reservoir arer. After the reservoir filling,the main engineering geological problems for digging areas are the softening action of water,failure by water pressure,inter scour failure and air blast.The authors predict the development of the failures by means of probability integraton method,experiential method and critical depth method and evaluate the stability of the site after filling,and then propose the treatment menthods.更多还原
