摘　　要：为满足BIM对水利水电地形建模的高精度要求,基于应用广泛的TIN格式展开研究,提出了地形模型精度的量化指标,对常见的3种地形建模方式进行了分析,最后基于实际工程地形数据进行了对比试验。试验结果表明:采用等高线建立地形模型可以在高精度和轻量化之间取得较好的平衡,是目前较为理想的地形建模方法,适合在水利水电行业BIM地形建模中推广应用。In order to meet the high-precision requirements of BIM for water conservancy and hydropower terrain modeling,based on the widely used TIN format,we quantified the indicators for terrain modeling accuracy,and analyzed three common terrain modeling methods,and finally conducted comparative experiments based on actual engineering terrain data.The research results showed that using contour lines to establish terrain models can achieve a good balance between high accuracy and lightweight.It could be currently an ideal terrain modeling method,and suitable for promotion and application in BIM terrain modeling in the water conservancy and hydropower industry.
