瑞丽江一级电站厂房GIS 沉降缝三向测缝计资料分析

Data Analysis of Settlement Joint Three-Directional Joint Meter for Powerhouse GIS in Ruilijiang Ⅰ Hydropower Station

对瑞丽江一级电站厂房GIS沉降缝三向测缝计及观测资料进行了介绍分析。从持续开展多年的测值分析可看出:厂房基础开挖完成及上部主体结构建设形成及之后的一段时间内,厂房各部位沉降速率不同而有相对位移趋势;在一定时间的沉降变形之后,变形速率逐渐减缓,变形趋势已不明显;经过近10a的沉降变形,厂房GIS沉降缝三向测缝计测值整体已趋于收敛。

This paper describes the three-way joint meter and observation data for settlement joints of GIS powerhouse in Ruilijiang Ⅰ Hydropower Station. It can be seen from the data that the settlement rate of each part of the powerhouse is different and there is a relative displacement trend after the foundation excavation of the powerhouse and the formation of the upper main structure. After settlement and deformation for a certain time, the deformation rate gradually slows down and the deformation trend is not obvious. After nearly 10 years of settlement deformation, the measured value of three-way joints of GIS settlement joints of powerhouse has converged.
