会东矿西边坡的变形及位移观测

在对水平位移观测资料的误差分析中,用误差椭圆替代点位中误差来计算观测的误差量,以便确定是边坡位移还是测量误差。在垂直位移观测中以两次高程的中数值作为观测点的最后高程,并取高程较差的一半作为两次高程观测平均值的中误差。观测结果表明,无论在水平或垂直方向上,观测期内均无位移迹象。

DEFORMATION OF AND DISPLACEMENT OBSERVATION FOR THE WEST-SLOPE OF THE HUIDONG SURFACE MINE

In error analyses for horizontal displacement measurement data, the observed errors are calculated with error ellipse instead of point root - mean - square errors, so as to judge whether they are just slope displacement or the measuring errors.For vertical displacement, the determination of each height is based on the mean of twice surveying values at the point, and half of the difference between the twice measured heights is taken as the root-mean-square errors of the measured height values. The observed results indicate that, during the observation period, there is no evidence of horizontal or vertical displacement.
