基于三维地质模型的坝基灌浆工程可视化分析

利用 Struts 和 Hibernate 技术，对灌浆数据进行采集和整理，在灌浆分析系统中将这些灌浆数据转化为三维灌浆孔模型，实现三维地质模型和灌浆数据耦合；在耦合模型的基础上对灌浆效果进行可视化分析：对任意排灌浆孔模型进行三维地质模型剖切，揭示每排灌浆孔模型的不良地质体垂直分布情况；通过改变单位注灰量较大灌浆孔模型的颜色属性，耦合其对应的三维地质模型，从而实现单位注灰量在地质模型中的可视化分析；在灌浆参数基础上自动生成其对应的综合剖面，将地质条件耦合到剖面中，赋予综合剖面图地质信息属性；通过对任意灌浆孔段进行地质信息数字化，明确每个灌浆孔段是否通过不良地质体以及各个不良地质体的高程分布；以施工单元为基准，对单位注灰量和地质信息进行耦合统计分析。通过工程应用实例表明，基于三维地质模型对整个坝基灌浆工程的可视化分析，可以有效指导灌浆工作并能对灌浆效果做到及时、有效的反馈分析，为工程管理人员做出快速的决策提供可靠的依据，从而提高工作效率和工作水平。

Visual analysis for grouting engineering of dam foundation based on 3D geological model

By means of Struts and Hibernate techniques,the grouting data are collected and sorted and converted to grouting hole model in grouting analysis system.Then the coupling between 3D geological model and grouting hole model is achieved.Visual analysis of the effect of grouting is based on the coupling model.The 3D geological model is cut along any grouting platoon so as to reveal the vertical distribution of unfavorable geologic body.The color attribytes of grouting hole model with larger unit grouting are changed,and the corresponding 3D geological model is coupled to achieve the visual analysis of the unit grouting.The comprehensive profiles automatically generating are based on grouting parameters,in which geological conditions will be coupled,and the geologic information will be shown in the comprehensive profiles.The geological information of any grouting hole model is digitalized to learn the grouting hole model whether or not to go through unfavorable geologic body and their elevations.On the basis of construction unit,statistical analysis for unit grouting and geological information is performed.Application examples show that the visual analysis of grouting engineering based on 3D geological model can effectively guide the grouting process and obtain a timely and effective feedback to grouting effects,and it will provide a reliable basis for decision-making of project management so as to improve the efficiency and level of work.
