| 摘 要： | 为了准确分析采矿引起的地表沉陷变形对地表高压供电线路的影响,采用威布尔(Weibull)分布法计算地表下沉与偏斜值的大小。威布尔分布法计算充填采矿地表变形能够将地表变形的多个参数用于计算,并且函数便于用MATLAB编程处理。通过冀东一个铁矿的计算实例说明,采用充填采矿法控制地表变形后高压供电线路能够安全运行,该计算方法能够满足工程计算需要。

| Abstract: | Weibull distribution was been used to calculate the ground subsidence and inclination value, in order to analysis accurately the influence of ground subsidence caused by underground mining on high voltage electric power lines. Many parameters could be used to calculate ground deformation due to backfill mining when Weibull distribu- tion method was used ; and the function could be solved by MATLAB program. An example of analysis of iron mine in the east of Hebei was given, and the results showed that the effect of reducing ground subsidence was notable and the high power line was working normally. It was accurate enough to calculate ground deformation by using Weibull distribution. |
