楠溪江供水工程施工期观测资料分析

楠溪江供水工程观测设施设置了闸基渗压计、闸段伸缩缝测缝计及闸室底板钢筋计等仪器设备。本文对工程施工以来的观测数据进行整理分析,为工程验收提供依据。通过分析得出,水闸表面变形较小,各闸段之间相对变形量较小,水闸稳定,整体性好;闸基渗压计测值变化稳定,测值较小;钢筋计测值较小,最大拉压应变均在设计范围。目前未发现异常现象,水闸处于正常状态。

Analysis on observation data from construction period of Nanxijiang River Water Supply Project

For the observation facilities of Nanxijiang River Water Supply Project，the osmometers in dam foundation，the joint meters in-between expansion joints of gate section，the steel bar gauges in bottom slab of gate chamber，etc. are installed. The observation data got since the construction of the project are disposed and analyzed herein，so as to provide a basis for the project completion acceptance. Through the analysis，it is obtained that the surface deformation of the sluice is less with smaller relative deformations in-between all the gate sections，the sluice is stable with a better integrity，the changes of the observation values from the osmometers in dam foundation are stable with smaller observation values and the observation values from the steel bar gauges are smaller with all the values of the maximum tensile-compressive strains within the design range concerned. At present，no any abnormal phenomena are found out，thus the sluice is in a normal status.
