【摘要】 固体地壳的应力状态是地壳的最重要的性质之一。地壳表面和内部发生的各种构造现象及其伴生的各种地质灾害都与地壳应力的作用密切相关。地应力测量与监测不仅为深入认识地震的孕育和发生机制,进而为强震预测提供重要的科学依据,而且也是地球动力学基础研究的重要组成部分,此外,还将为国家重大工程建设,如深埋隧道、水电工程、深部能源开采、核废料处置场地的选址等深部地下工程的勘测设计提供重要的技术支撑。地应力测量与监测技术实验研究是国家科技专项"深部探测技术试验研究"所属的第六项目。该项目的主要任务是,围绕专项的总体科学目标,开展系统的地应力测量与监测及其实验对比研究,通过室内实验和野外现场实际测试,对现有各种主要的地应力测试技术的适用性和可靠性进行总体评价和研究,进而针对存在的问题开展研究和相关测试系统的创新性研发,从整体上提升现有主要地应力测试方法的技术水平;在北京地区建立深孔地应力综合观测试验站;在青藏高原东南缘开展地应力测量与监测,构建地应力监测网络,进而将其打造成具有国际影响力的地球动力学野外试验基地。更多还原

【Abstract】 In-situ stress state is one of the most important characteristics of the earth’s crust.Various tectonic phenomena occurring at the surface and in the interior of the earth as well as the subsequent geo-hazards are immediately related to the actions of the crust stress.In-situ stress measurement and monitoring can provide important scientific inference for the understanding of the mechanism of the pregnancy and occurrence of the earthquake,and also serve as the important foundation for the prediction of strong earthquakes.In addition,in-situ stress measurement and monitoring will provide technique support for national key projects,such as deep buried tunnel,hydropower project,deep resources exploration,and nuclear waste disposal.Experimental studies of the technique of in-situ stress measurement and monitoring is the 6th item of the national project "Deep Exploration Technology and Experimentation".The main tasks are to carry out in-situ stress measurement and monitoring and comparative study and,through laboratory test and in-situ test,to give the evaluation regarding the adaptability and reliability of the main methods of in-situ stress measurements.On such a basis,the researchers will carry out relevant study and exploration of new instruments and systems for in-situ stress measurement and monitoring,promote the technique of in-situ stress measurement,and establish deep borehole comprehensive observing station in Beijing area.In east and south boundaries of Qinghai-Tibet Plateau,in-situ stress measurement will be conducted systemically,and stress monitoring network of this area will be established so as to gradually turn this area into a field test platform for dynamics study.更多还原
