Abstract:

By stress and strain observation of the dam, its safety condition can be evaluated effectively. Combined with the measurement by five-direction strain gauges installed in powerhouse section, basing on the MATLAB calculation and drawing program, by use of deformation method to calculate the concrete stress, the paper analyzes the stress status on the monitoring section, for reference.

Key words: strain gauge group, stress and strain, data analysis, MATLAB program

摘要： 分析混凝土应力应变监测资料，可以有效地了解相应结构物的受力性态及其安全状况。利用某水电站工程厂房坝段安装的五向应变计组施工期监测资料，基于MATLAB计算及绘图程序，运用变形法计算混凝土的应力，综合分析厂房坝段设计监测断面混凝土的应力状况。
