孔底解除法在上海综合深井钻孔原地应力测量中的应用

Application of Hole-bottom Relief Method in Stress Measurement of In-situ Bored Hole in Shanghai

上海综合深井项目建设第一阶段完成,作为国内第一个建成的综合深井地震观测站在建设初期开展了许多有关地球物理基础数据的收集,其中在张江综合深井进行了用孔底解除法对深井原地应力的测量。经过综合分析,给出试验区地应力的赋存规律和基本特征,为上海市地震局浦东地震监测中心地震综合观测深井综合观测仪器安装提供地应力背景资料。

The first phase of Shanghai comprehensive deep well project construction is completed, as the first comprehensive deep seismic observation station built in the early construction, which carried out a lot of relevant basic geophysical data collection, in which deep Zhangjiang integrated were measured in situ with deep hole bottom relief method. Based on the comprehensive analysis, the regularity and characteristics of ground stress in the test area are given, which provides the background information for the installation of the comprehensive observation instrument for the comprehensive observation of the Pudong earthquake monitoring center of Shanghai Earthquake Agency.
