| 摘 要： | 用曲线拟合法解算矿山开采沉陷领域中下沉盆地剖面表达式的参数，其实质类似于测量间接观测平差问题。当新参数个数少于原参数个数时．或当剔除了无效观测值后的观测数目少于新参数个数时，参数就无定解．进而说明了使用参数识别方法解算地表移动参数的可识别程度。

| Abstract: | he problem that the parameters of subsidence profile functions obtained from in-situ data by curve fitting method, by its nature, is one of special indirect observation adjustment problem If the number of new parameters is iou than the original ones or the number of observation values after deleting out the useless ones is less than the new parameters, the solution of parameters equa tions are undetermined therefore, the identifiability of parameters of profile functions is limited that is discussed at the fields of subsidence due to underground mining. |
