摘 要：对 BIM 坐标系与施工坐标系在不同基准下的转换进行了研究，研究发现虽然 BIM 坐标系与施工坐标系原点的选择及起算方向不同，但两者之间存在几何关系和共同的基准。通过坐标系之间的关系利用计算公式和 CAD 软件两个方法对坐标系的转化进行分析研究，利用计算公式主要是通过坐标系之间的几何关系进行转化；利用 CAD 软件主要是通过坐标系之间的共同基准进行转化，以期使 BIM 技术在核电工程建筑行业中更加全面地应用及推广。

Abstract: This paper studies the transformation between BIM coordinate system and construction coordinate system under different benchmarks. It is found that although the origin selection and starting direction of BIM coordinate system and construction coordinate system are different, there is a geometric relationship and common benchmark between them. Through the relationship between coordinate systems, the transformation of coordinate system is analyzed and studied by using calculation formula and CAD software. The use of calculation formula is mainly transformation based on the geometric relationship between coordinate systems; the use of CAD software is mainly transformation based on the common benchmark between coordinate systems. In order to make BIM Technology more comprehensively applied and popularized in nuclear power engineering construction industry.
Keywords: BIM coordinate system; construction coordinate system; different benchmarks for nuclear power projects; coordinate system transformation
