摘 要:华北平原大型引调水工程具有跨越地层单元广、工程数量多、工期集中等特点。本文结合GeoStation软件的自动建模、半自动建模及分区块建模功能,建立了一套大型线型水利工程的建模流程方法;将工程划分为独立单元进行分区建模,解决了建模操作面单一的困难,兼顾了模型质量与建模效率的平衡;介绍了建模过程中的实际经验和模型应用情况,为大型线型水利工程的三维建模和模型应用提供了参考。

Abstract: The large-scale water diversion project in the North China Plain has the characteristics of a wide range of strata units, a large number of projects, and a concentrated construction period. In this paper, combined with the automatic modeling, semi-automatic modeling and block modeling functions of GeoStation software, a set of modeling process methods for large-scale linear water conservancy projects had been established; the project planning was divided into independent units for partition modeling, which solved the difficulty of a single modeling operation surface and took into account the balance of model quality and modeling efficiency; the actual experience and model application in the modeling process were introduced, which provided a reference for the three-dimensional modeling and model application of large-scale linear water conservancy projects.

我国是水资源短缺的国家。特别对于华北平原而言,水资源时空分布不均、水环境恶化、生活工业用水供需紧张已经成为制约当地社会经济快速发展的关键因素[1]。兴建大型跨区域引调水工程在加强可利用水资源管理、保障居民生活用水质量、促进受水区社会经济发展方面有难以替代的作用,是提升区域水资源承载力的有效途径[2]。仅河南省已投入运行及在建的大型平原区引调水项目有:南水北调中线及其配套工程、引江济淮(河南段)工程、赵口灌区工程、小浪底北岸灌区工程、西霞院水利枢纽灌区工程等。
随着地学信息化的发展,数学地质正向“数字地质”发展[3-4],建筑信息模型(Building Information Modeling,BIM)为岩土数字化工作带来了契机与挑战[5]。相对于工业民用建筑行业已日趋成熟的BIM技术水平,水利水电行业以涉及专业多、建设周期长、建设内容繁杂等特点在BIM领域仍处于初级发展阶段。……
