| 摘 要： | 港区陆域形成的填挖方量对工程经济性影响非常大,寻找精确地计算港区陆域工程量使纵向设计最优化的方法是港区工程全寿命周期各个环节的关键。基于传统方法的计算原理与应用现状分析了现有方法在港区土方计算中存在的问题,借鉴建筑信息模型BIM(Building Information Modeling)思想,对Civil3D的土方计算原理与操作流程进行研究,最后以某港区石化仓储库区场平方案为例,参考传统计算软件HTCAD的计算结果,验证了Civil3D在港区工程量计算中的便捷性与可靠性。结果显示:Civil3D的计算精度比HTCAD高7%~20%,计算速度是HTCAD的数十倍,在修改过程中计算速度达数百倍。研究成果为采用Civil3D进行港区陆域土方计算提供理论和技术依据。

| Abstract: | The earthwork quantity in the land of a port area has a great influence on the economy of the project. In each link of the whole life cycle of the port area project, therefore, the urgent task is to find out an accurate method for calculating the site earthwork quantity in port area and optimizing the longitudinal design. Based on the calculation principles and application status of traditional methods, the problems in earthwork calculation in the port area by using the existing methods are analyzed. The principle and operation processes of Civil 3D in the earthwork calculation are studied by drawing lessons from the Building Information Modeling (BIM). By relying on the scheme for leveling site in the petrochemical warehouse area in a port area and taking the calculation results of the traditional computing software HTCAD as a reference, the convenience and reliability of Civil 3D in the calculation of engineering quantity in the port area are tested and verified. The results show that the computational accuracy of Civil 3D is 7%~20% higher than that of HTCAD; the computational speed of Civil 3D is tens of times as much as that of HTCAD; and the modification process is even 100 times faster. This study provides theoretical and technical base for using Civil 3D to calculate the earthwork quantity in the land of the port area. |
