大起伏地区快速高程控制测量研究

摘要

Level measurement for large rolling terrain elevation control survey work is slow, error accumulation big problem, stop using the total station is located in the middle vertical control survey method in large rolling terrain. Correction of the measurement distance by elevation correction and projection surface naturalization process, for total station measurements Stationing middle influencing factors were analyzed, using attached together, closing the route precision height measurement requirements for the control, verification total station by measuring examples Stationing instrument in the middle of a large undulating area Rapid height Control Measurement is practical.%针对水准仪测量法在大起伏地区高程控制测量中作业速度慢、误差累积大的问题，采用全站仪中间设站法在大起伏地区进行高程控制测量。通过高程面归化改正和投影改正对测量距离进行处理，对全站仪中间设站法的测量影响因素进行分析，采用附合、闭合高程测量路线精度要求进行把控，通过测量实例验证全站仪中间设站法在大起伏地区快速高程控制测量中是实用性。
