摘要
为合理利用边坡的几何信息和物理信息,控制几何观测异常对形变参数估计的影响,利用边坡的力学状态信息建立了滤波模型以及参数约束方程,通过融合观测信息和边坡的力学信息给出了带约束的滤波算法,从而减弱了观测异常对形变参数估计所带来的影响,提高了形变参数解算精度.
To make rational use of geometric and physical information of slope,and to control the influence of the outliers on deformation parameter estimator,a constrained filtering model using mechanical state information of slope was given.The model integrates statistical information about observation and information about mechanical state and geological conditions of slope.The algorithm given makes full use of geophysical model information to eliminate the influence of abnormal observation and improve the precision of deformation parameter estimator.
