本文从样条函数的概念出发,建立了岩移预计的一种新方法——样条函数法。文中给出了适用于各种地质采矿条件下地表任意点沿任意方向的移动变形值预计公式,指出了其预计步骤,并用实测资料对预计公式进行了验证。 本文的研究表明:新的预计方法具有一系列优点:参数的几何、物理意义明确;函数的形式简单;适用范围广;能够全面地描述下沉盆地特征;便于推广。 In this paper, starting from the concept of spline function, a new method of rock migration prediction is established, spline function method. In the paper, a prediction formula of moving deformation value applied to arbitrary direction along the surface at any point under various geologic mining conditions is given. The predicted steps are given, and the predicted formula is verified with the measured data. The research shows that the new prediction method has a series of advantages: the geometrical and physical meaning of the parameters are clear; the function forms are simple; the scope of application is wide; the features of the subsidence basin can be fully described;
