摘要
Abstract
Aiming at the non-strict stress-free state existed in the non-stress meter embedded in the high arch dam, the structure and embedding ways of the square and circular tubes are designed, and they are compared with the common conical-tube. The in-situ tests show that the concrete linear expansion coefficient of conical-tube is smaller than that of square and cir-cular tubes. The least square method, statistical regression method and genetic algorithm are adopted for the inversion analysis of the measured data of non-stress meter. The results of statistical regression method and the bionic genetic algorithm are basically identical;however, the results of least squares are different from the above two methods and it is easy to be affected by subjective factors.关键词
