南水北调工程结构大部分为薄壁混凝土结构,干缩是其破坏的主要因素之一。文章基于混凝土干缩试验测量方法指出现有测量方法尚存在无法测得早期干缩的不足,进一步开展基于试验方法和试验设备的改进将是以后研究工作的重点,其将为工程设计提供依据。
Most of the structure of the South-to-North Water Diversion Project is a thin-walled concrete structure, and dry shrinkage is one of the main factors of its destruction. Based on the measurement method of concrete shrinkage test, the paper points out that the existing measurement methods still can not measure the shortcoming of early shrinkage. Carrying out the improvement based on the test method and the test equipment will be the focus of future research work, which will provide the basis for engineering design.
