关于三维地下水渗流数学模型定解条件的讨论

摘要

The paper indicates the acquisition methods for primary conditions and boundary conditions, and the treatment methods for the soil layer consolidation in the establishment process of the three-dimension underground seepage at seashore areas, concludes a set of related parame-ter empirical value in Tianjin to assist the professional staff to realize the excavation dewatering evaluation of deep foundation pits and respective environment geology, so as to provide some basic quantitative calculation methods for the deep foundation pits’ influence on surrounding environ-ment and the forecast of the scopes.%论述了在滨海地区建立三维地下水渗流模型过程中初始条件、边界条件的获得方法及土层固结状况的处理方法，并得到了一套天津地区相关参数的经验值，能够帮助相关专业人员提高对当前深基坑开挖降水评价及相应环境地质问题的认识，对因深基坑开挖对周边环境的影响程度、范围的预测提供了基本的定量计算方法。
