摘　　要：渡槽充水试验是保证正常通水前的试通水,要求对结构的安全性、稳定性及充水效果等进行全面的检查,同时对设计理念进行初步验证,目的是确保渡槽运行安全。论文以淠河总干渠混凝土渡槽充水试验为例,对渡槽的挠度变形和沉降观测方法进行了初步探索,并根据项目实际情况,提出了针对性的适用变形监测方案,同时进行了误差和精度分析。结果表明,此方案克服了各种不利条件的限制,同时,满足渡槽充水试验监测的精度要求。The water filling test of the aqueduct is a comprehensive inspection of the safety,stability,and water filling effect of the structure before ensuring normal water supply.At the same time,it is also a preliminary verification of the design concept,aiming to ensure the safe operation of the aqueduct.In the water filling test of the concrete aqueduct of the Pi River main channel,a preliminary exploration was conducted on the deflection deformation and settlement observation method of the aqueduct.Based on the actual situation of the project,a targeted and applicable deformation monitoring scheme was proposed,and error and accuracy analysis were conducted.The results showed that this method not only overcomes the limitations of various unfavorable conditions,but also meets the accuracy requirements of the water filling test monitoring of the aqueduct.
