摘　　要：对中间法三角高程测量在大桥主墩沉降监测中的应用进行了数学模型的建立和精度分析,并以重庆市某跨江大桥主墩沉降监测为例,对该方法进行了应用说明,中间法三角高程测量解决了被水淹没的大桥主墩沉降监测无法采用直接水准进行测量的难题。This article has carried on the mathematical model establishment and the precision analysis to the middle method trigonometric leveling in the bridge main pillar subsidence monitor＇s application, and take Chongqing some cross river bridge main pillar subsidence monitor as the example, has carried on the application explanation to this method, the middle method trigonometric leveling solved has been flooded no bridge main pillar subsidence monitor to be unable to use the direct standard to carry on the survey the difficult problem.
