地球动力学研究中的地壳深部原地应力测量

In-situ Stress Measurement in the Deep Borehole for Geodynamics Study

一、引言原地应力测量对矿山开采、地下建筑工程、水利水电工程的设计与施工、油气田和地热能的开发利用、核废料处理、核电站建设及工程稳定性评价等具有重要的实际意义. 近年来,随着地应力测量的进展和资料积累,地应力测量日益受到重视.地壳内的各种地质构造现象和地震,及其伴生的物理化学现象都与地壳应力的作用密切相关.

Geodynamics,which is now popular in earth science,is a very important branch in the basic research of earth science.In the study of geodynamics,in—situ stress measurement in the deep borehole is of great significance,and its surveying data are very important for study on the formation in geodynamics,therefore,have attracted great attention of the earth scientists.Here,the research situation and progress on in-situ stress measurement in geodynamics studies are presented.
