Civil 3D在多级边坡场地设计中的应用

Application of Civil 3D in Design of Multi-level Slope Site

本文以某干港项目为例,通过Civil 3D预设的放坡到相对高程和放坡到距离的标准,生成多级放坡曲面,结合曲面分析中求两曲面之间的最小距离,得到曲面交线,以交线作为边界添加到多级放坡曲面,最后通过曲面粘贴功能形成设计曲面,实现了多级放坡建模,并以设计曲面为基础,简要介绍了土方量统计、土方施工图和断面图生成的思路。本文应用Civil 3D完成多级边坡场地设计的方法,可供设计人员在工作中参考。

Based on a dry port project,a multi-level slope curved surfaces are produced by using CIVIL 3D to pre-set the sloping standard of relative elevation and distance.The intersection line of curved surfaces can be obtained by calculating the minimum distance between two curved surfaces based on the surface analysis.And then the intersection line is added to the multi-level slope curved surfaces as the boundary.Finally the design curved surface is built with curve pasting function to achieve multi-level slope modeling.The design curved surface also serves as a basis for the brief introduction to the idea on the statistics of earthwork quantities,detailed drawing of earthwork and cross section forming.CIVIL 3D has been applied in the design of multi-level slope site,which will provide the designers a reference in similar projects.
