摘要:
|
随着海上建筑增多,急需一种适合于远离岸线,特别是在台风时也能够准确便捷地对地基进行水下自动监测的仪器。采取了诸多措施,将测控系统和设备构成的监测系统,放在远离岸线的海底进行长期监测。经几项工程均长达一年半的监测实践表明,监测数据规律性很好、长期稳定性强、无零飘现象、通讯传输便捷而可靠。

With the increase of marine structures,it has become more urgent to develop an automatic monitoring instrument that can accurately and rapidly measure and monitor underwater foundation and is suitable to work far away from coastline and especially in typhoon conditions.Take a series of measures,place the monitoring system made up with measuring and controlling instruments and equipments on the sea bottom far away from coastline to monitor for long time.The practice of several projects(all more than one year and a half)shows the regulation of monitoring data is very good,the stability for long time is better,there is no zero drift,the telecommunication transmission system is portable and reliable.
