基于双基准的沉降监测系统设计

Design of Settlement Monitoring System Based on Double Datum

为了解决压差式静力水准仪受温度密度等环境因素影响而导致使用过程复杂及测量误差大的问题,该文以静力水准仪为核心传感器,采用温度补偿和多基准校准的方法对系统进行了优化,研发了一套沉降自动化监测系统。经验证测试结果表明,该监测系统能减少系统误差,降低工程复杂度,并在某地铁线的安全监测中能够良好运行,具有较高的工程实用价值。

In order to solve the problems of complex use process and large measurement error caused by the environmental factors such as temperature density,etc.,this paper takes the static level as the core sensor,optimizes the system by using the methods of temperature compensation and multi benchmark calibration,and develops a set of automatic settlement monitoring system.The verification test results show that the monitoring system can reduce the system error,reduce the complexity of the project,and operate well in the safety monitoring of a subway line,which verifies that the monitoring system has high engineering practical value.
