利用CIVIL 3D进行海港工程疏浚设计方法研究

Study on Design Method of Seaport Dredging Works based on Civil 3D

本文在南方某海港工程港池航道工程设计中引入BIM正向设计,利用CIVIL3D建立了地形曲面和地质曲面模型,建立采样线,对地形曲面、设计曲面、地质曲面进行采样;用断面法进行疏浚工程量计算,用程序自带网格施工图及其他软件等多种方法进行校核以验证计算准确性;通过材质定义,计算不同土类疏浚量并在断面图中表示;在设计完成后,按其自带的出图功能生成断面图组,批量对其表达形式、格式、显示内容进行统一调整,提高设计工作效率及准确性。可为类似工程引进BIM进行正向设计提供参考。

BIM forward design is applied in the harbor basin and channel project of a seaport in south China,and the models of topographic and geological curved surface are established by using CIVIL 3 D,and then the sampling lines are set for taking the samples of topographic,design and geological curved surfaces.Cross-section method is used to calculate the dredging amount,and the calculation accuracy will be verified by using grid construction drawing and other software based on the model program.The definitions of materials are used to calculate the dredging amount for different types of soil,which will be shown on the cross-section drawing.After the design is completed,the section drawings are generated by using the function of drawing production,and the expressing way,format and content are adjusted by batches to improve the design efficiency and accuracy.The above research will provide a reference for similar projects.
