摘要
变形监测是监测形变体安全与否的重要手段,而常规地面测量方法监测周期较长,难以实现远程实时监测。利用静力水准仪高精度、实时监测等优点,获取实验区域地表建筑物变形数据,分别从温度、延迟效应、液体材料及其他影响因素进行了详细的影响分析,并建立了各影响因素改正模型。数据分析结果表明,当填充液体为玻璃水时,静力水准仪经过误差改正后,监测系统高程测量精度为0.19 mm,2个监测点间高程差监测精度为0.08 mm。
Deformation monitoring is an important way to monitor the deformation safe or not,but conventional ground survey method has a long monitoring period and is difficult to achieve remote real- time monitor. Hydrostatic level measurement has higher measurement precision and can realize real- time monitor. According to the deformation data of surface building in the experimental region,the temperature effect,the delayed effect,the liquid material effect of the measurement system have been studied detailedly,the correction models of the effect factors have been established. As it is shown in the data analysis,if filling liquid is glass- water,hydrostatic level measurement has higher measurement precision after correcting the effect factors. The height determination precision can achieve 0. 19 mm,the level difference precision can achieve 0. 08 mm.
