深部应力测量技术研发进展与展望
Research progress and prospects of deep stress measurement technology
摘要
Abstract
[Objective]With the implementation of the national strategy of seeking resources,safety,and space from deep Earth,the frequency and intensity of various engineering disasters caused by in-situ stress have also significantly increased.At the same time,in engineering fields such as underground gas storage and water diversion tunnels,using the minimum principal stress criterion to determine the upper limit operating pressure can to some extent improve the storage capacity of underground space or reduce tunnel support costs.Overall,the importance of in-situ stress in the process of advancing towards the deep Earth is becoming increasingly prominent.However,there are still bottlenecks in the demand oriented deep stress measurement technology,such as insufficient detection capability and low reliability of measurement results,which restrict the application of in-situ stress data in solving scientific problems such as tectonic activity,deep resource development,and space utilization.[Methods]On the basis of a brief review of the current development status of in-situ stress measurement technology,this article focuses on the progress and achievements of the team in theoretical research,technical development,and application practice of in-situ stress measurement in recent years.[Results]It points out the challenges faced by deep in-situ stress measurement in terms of theoretical methods and technical aspects,and proposes a research route and direction for deep borehole stress detection in conjunction with the current national science and technology major project"Key Technologies and Experiments for Deep Stress Detection".[Conclusion]The goal is to develop high,precise,and advanced in-situ stress measurement technology and equipment,construct an in-situ stress observation technology system covering the depth space of the hypocenter source.[Significance]Deep borehole in-situ stress detection technology holds significant potential for applications in geodynamics research,deep resource exploration,and disaster prediction and prevention.关键词
