| 摘 要： | 目前对地面沉降的研究和计算中，由于地质情况复杂、土体的变异性不容易掌握，对于土体参数的选取多数是根据经验值，具有不确定性。特别是在大面积的地面沉降计算中，这种不确定性更为严重。采用数值分析法，以Biot固结理论为基础，应用有限元软件Adina，建立了单井抽水的地面沉降模型，分析各参数在抽水过程中对地面沉降的影响，从而确定敏感参数，以期对地面沉降研究中的参数选取提供有价值的指导。

| Abstract: | Due to the complexity of geology condition and the variability of soil, the soil parameters employed in calculation of ground subsideence are empirical values; they are usually uncertain. It is more serious for the calculation of ground subsidence of large scale area. Based on the Biot consolidation theory, numerical analysis and the FEM software –Adina, a land subsidence model of water withdrawal of single well is established; and the effects of sensitive parameters of ground subsidence during the water withdrawal and the appropriate parameters are determined. |
