基于CIVIL 3D的疏浚工程量计算分析

Calculation and Analysis of Dredging Quantities Based on CIVIL 3D

本文采用CIVIL 3D分别建立了某内河A、某内河B和某内河C的部分地形模型,并用曲面放坡和距离放坡建立了疏浚模型,计算了航道的疏浚工程量。所得数据传统软件所得数据相差较小,验证了模型的正确型。通过不同航道和不同建模方式的对比分析发现,与传统软件所得数据相比,航道弯曲段的差异较航道直段的大。曲面放坡所得数据比距离放坡大,由于其对应于不同的实际工况,因此需要设计负责人择优选取。但本文研究成果为设计负责人在今后采用BIM设计时提供一些实验数据。

The topographic models are built by using CIVIL3D in order to simulate inland river A,B and C respectively,and a dredging model is established to calculate the channel dredging quantities by using curved surface sloping and distance sloping methods.The calculated results are less different form the data obtained by using the traditional software,which verifies the correctness of the model.Based on the comparative analysis of different channels and modeling methods,the differences among the bend sections of the channels are much more than that among the straight sections of the channels in comparison with the data obtained from the traditional software.The data obtained from the curved surface sloping method is larger than that from the distance sloping method.The design manager is responsible for selecting the suitable method according to real working condition.The study results will serve as the experimental data for supporting BIM design in the future.
