摘要
结合精密三角高程测量的原理,针对变形监测的特殊性,采用不量仪器高和棱镜高的中间观测法来进行精密三角高程测量,分析了精密三角高程测量的精度,从理论的角度验证了TCA2003全站仪精密三角高程测量在变形监测中替代二、三等水准测量的可行性。
According to the theory of precise trigonometric leveling and particularity of deformation monitoring, the paper introduces the middle observation method without measurement of the height of the instrument and prism to carry out precise trigonometric leveling, and analyzes the precision. The method of the TCA2003 total station precise trigonomet- ric leveling instead of second-order or third-order leveling is proved to be feasible in theory.
