从控制监测过程中的内部、外部要素以及现场作业条件着手，通过对几种典型监测方法精度分析及360°反射棱镜试验研究，最终选择全站仪极坐标法作为三峡升船机塔柱施工期变形监测的方法，并对运用该方法得到的长期监测数据成果进行了变形规律分析。分析结果表明：塔柱变形受温度影响大，温差越大，变形越大，温差小或恒温状态时变形很小甚至没有变形。

This paper begins with internal and external factors as well as field operating conditions during the monitoring process. According to the accuracy analysis which is done to several typical monitoring methods and the study which is done to the 360° reflecting prism test,the final choice is that total station polar coordinate would be used as the deformation monitoring method of Three Gorges Project ship lift tower during construction period,and deformation analysis is received using the long-term monitoring data obtained by the use of the meth-od. The results show that tower deformation is greatly affected by temperature;the greater the temperature differ-ence,the greater the deformation. It would be small deformation or even no deformation when temperature differ-ence is small or under constant temperature.
