摘要
本文根据鲁布革水电站原位试验洞实测位移,应用数理统计原理,通过有限元数学模型的回归分析计算,求解出岩体初始应力场和位移场。回归结果与实测位移、实测应力值相比较是一致的,且符合工程实际。本文的研究结果表明,以实测位移为依据进行回归分析计算,其方法是可行的,成果是可靠的,可用于实际工程。
In this paper, according to the field displacement measurement data of rock chamber modal test and the regression analysis of the finite element mathematieal model, the ground stress field of rock masses is determined. The calculated results are in agreement with the measured displacement and the measured stress. It is shown that the regression method based on the measured displacemcnt is feasible, the results are reliable, and it may be used in practical engineering.
