摘　　要：针对三棱柱模型无法准确表示不规则地层结构尤其是钻孔偏斜情况的问题,提出了一种基于广义三棱柱模型的覆岩弯曲带三维建模方法。该方法首先利用钻孔等原始信息,结合广义三棱柱模型,构建采动前覆岩地质三维模型;然后通过判别关键层位置确定弯曲带范围;最后通过估计覆岩弯曲带变形参数对采动前覆岩地质三维模型进行修正,建立采动后覆岩弯曲带地质三维模型。实例分析结果验证了该方法的有效性。For problem that tri-prism model cannot accurately represent irregular stratum structure especially borehole deviation,a 3D modeling method of bending zone in overburden strata based on generalized tri-prism model was proposed.Firstly,3D geological model of overburden strata before mining is constructed based on the generalized three-prism model by use of drilling raw information.Then range of bending zone is determined through distinguishing key strata position.Finally,deformation parameters of the bending zone in overburden strata are estimated to modify the 3D geological model of overburden strata before mining,so as to establish 3D geological model of bending zone in overburden strata after mining.The example analysis result verifies validity of the method.
