Review and Prospect of Researches on Determination Method for Crustal Stress
Abstract:Crustal stress determination is an important parameter for earthquake monitoring and forecasting, as well as a major geological parameter for the design and construction of oil exploration and civil construction projects. With the development of economy and the implementation of the "Belt and Road" project, a large number of large-scale engineering projects are put into construction, making it increasingly crucial to monitor and evaluate the stability of geological environment. Based on the analysis of the causes and influencing factors of ground stress, the paper reviews the development history of ground stress measureReview and Prospect of Researches on Determination Method for Crustal Stressment at home and abroad, systematically discusses the methods, principles and operation procedures of various types of ground stress measurement, clarifies the advantages and disadvantages of each type of measurement methods and their respective scope of application, and finally predicts the future development trend of crustal stress measurement. Therefore, It is expected to provide help for earthquake forecasting and guarantee the geological environment for the construction of oil and gas exploitation and civil engineering construction.
