一种沉降监测自动化静力水准测试装置研究
Study of an Automated Static Leveling Test Device for Settlement Monitoring

静力水准法是监测大坝垂直位移的有效方法，但液体与管壁之间的摩擦阻力对静力水准装置系统响应时间和测量误差影响很大，连通液体种类、连通管长度和管径都是可以改变的，但是环境温度是无法改变的，这也是静力水准装置极少在严寒地区野外环境下应用的主要原因。本文提出了一种连通管式监测设备管道系统响应时间和测量误差自动化测试装置，针对现有的监测装置不便于对静力水准平衡响应时间和测量误差测试的问题，得出适合实际工程的监测设计方案。
Static leveling is an effective method for monitoring the vertical displacement of dams. The friction resistance between the liquid and the pipe wall has a great influence on the response time and measurement error of the static leveling device system, the type of connecting liquid, connecting pipe length and diameter can be changed, but the ambient temperature cannot be changed, which is the main reason that the static leveling device is seldom applied in the field environment in the cold region. This paper proposes an automated testing device for response time and measurement error of piping system of connecting pipe-type monitoring equipment, which is not convenient for the existing monitoring device to test the response time and measurement error of static leveling equilibrium, and comes up with a monitoring design scheme suitable for actual projects.
