桥梁专业术语
1. 桥位地形图 (qiao wei di xing tu ) topography map of bridge site 应用地形测量的方法,测绘出桥位处地物、地貌的平面位置,并把地面的高低 起伏用规定的符号绘制成正射投影图。桥位地形图是经过实地测绘的,能客观的反
映桥位处地面情况,所以成为桥梁规划设计的重要依据。 2. 桥位地质剖面图 (qiao wei di zhi pou mian tu) geologic section drawing of bridge site
通过假设的方法,把实际上看不见的桥位地质资料情况,按岩石的种类、地层、 年代、地质构造单元等绘制于图上,形成桥位地质剖面图。它是基础设计的重要依 据。
