移动棱镜法三角高程测量在软基处理工程中的应用

Application of Moving Prism Trigonometric Leveling in Soft Foundation Treatment Project

在港口工程建设中越来越多地采用全站仪进行三角高程测量,但在常规的全站仪三角高程测量中人工立镜的方式在软弱地基中有其局限性。在工程测量实践中摸索出采用移动棱镜进行三角高程测量的方法,该方法将常规三角高程测量中的的人工立镜改为移动棱镜,使软弱地基中三角高程测量的施测速度更快、更经济,也更安全。

Total station instrument is increasingly used for trigonometric leveling in port projects. In conventional trigonometric leveling by total station instrument, manually-operated-mirror method is restricted in soft foundation. In engineering survey trial, the moving prism trigonometric leveling is created, in which moving prism replaces manually-operated-mirror. In that case, the trigonometric leveling of soft foundation becomes quicker, safer and more economical.
