水利水电工程土石方开挖可视化设计方法初探

土石方开挖是施工组织设计中的重要组成部分，它对土石方工程的概预算、施工的进度安排以及土石方工程填挖平衡的设计都有很大的影响。传统的土石方设计方法由于平面地形图可视性差以及求各网格点高程值的烦琐性，使得这项工作量很大，并且有时会因为网格划分的不合理，而产生较大的误差。为此，本提出土石方开挖的可视化设计方法，该方法弥补了传统方法的不足，能够很好地满足设计需要；同时，计算结果提供的土石方开挖后形态仿真图，能够呈现不同项目、开挖部位及断面特征（坡度），可以为组织开挖工程设计提供可视化决策信息。

Research on Visual Design Method for Earthwork Excavation of Hydraulic Engineering

Earthwork excavation is an important item in engineering design.The budgetary estimate,schedule,and design of balance of filling and excavation are greatly influenced by the earthwork excavation.The existing method of earthwork design is miscellaneous by rea-son of the unperfection of planimetric relief map's visibility.Moreover,it has many errors because of the unrational dividing of gridding.A digital method,which can make up for the existing method,is presented in this paper,and the expectation of design can be met.The simulation modality picture can show different projects,situs,and section characteristic(grade)from the calculation results.The informa-tion of visual decision-making can be provided for the earthwork excavation design.
