A COMPARISON OF THE RESULTS OF STRESS MEASUREMENTS OBTAINED BY AE WITH THAT BY HYDROFRACTURING AT TAIYUAN,SHANXI
-
摘要: 本文在说明AE(声发射)法在引黄工程地应力测量实施过程中的作用之后,简要介绍了AE估测法和估测结果,并与水压致裂法测量结果相对比,给出测量结果的评价性结论是两法测量结果近乎一致。AE法估计500m深度最大主应力值为26.7MPa。Abstract: Acoustic Emission stress determination method was applied at Taiyuan, Shanxi, for the water-diversion project and the results obtained are given in the paper.A comparison of the results with that by hydrofracturing shows a good agreement of the measurements. The maximum principal stress estimated by AE at a depth of 500m is 26.7MPa.
