摘要
水平位移观测是高大建(构)筑物形变监测中不可缺少的部分。本文介绍了斜拉桥塔塔顶水平位移监测中的2种观测方法及其精度分析,表明曾经一度被人们忽视的常规观测方法能够弥补特殊情况下高新技术的不足,体现其实用性,指出观测方案应该根据实际情况进行最佳效益分析、最佳观测方案优化设计。
The horizontal displacement surveying is essential to the deformation monitoring of tall constructions. This paper introducesthe two horizontal displacement monitoring methods of the cable-stayed bridge tower tops and their precision analysis. It states that the routine surveying methods which was once ignored can make up for the shortage of the advanced technique under some special circumstances, embodying its practicality. It puts forward that the surveying methods should analyze the best benefit and design the best surveying method on the basis of the actual situation.
