汶川地震引领爆裂动力学理论发展
The Wenchuan Earthquake Promoting the Development of the Theory on Burst-dynamics
【摘要】 汶川地震揭示了震源包体的存在,体积在2500万m~3至7700万m~3之间,推动了以力学定则和能量守恒定律为基础的严格的地震理论——爆裂动力学理论的建立和发展。地震是断裂结构包体内积聚的能量达到爆裂压力经触发发生的爆裂-塌缩链锁过程,8级地震释放的能量相当于15颗百万吨TNT当量的核弹。震中的分布遵循波叠加规则。地震结构体内的高压高温流体对围岩的作用,将引起力学、物理、化学和生物变化;震中理论同这些变化监测相结合可以对地震作出预报。中海油林昌荣查油气储体的方法值得推广于地震包体的诊断。地震研究一定要从块体"挤压"的误区中解放出来。
【Abstract】 The Wenchuan Earthquake reveals the existence of occlusion body in seismogenetic fault with a volume of 25 million m~3 to 77 million m~3,promoting the establishment and development of the Burst - dynamics theory - a stricter seismic theory based on the rule of mechanics and the law of conservation of energy.Earthquake is a burst-collapse chain process triggered when the accumulated energy inside occlusion body in a fault structure reaches the rupture pressure,and the energy released in an M8 earthquake is equivalent to 15 nuclear bombs each with a yield of 1 megaton of TNT.The distribution of epicenter follows the rule of wave superposition.The action of high-pressure and high-temperature fluid inside a seismic structure on surrounding rock will cause mechanical,physical,chemical and biological changes.The combination of the monitoring results of these changes with the epicenter theory can help forecast an earthquake.To diagnos oil-gas reservoir method proposed by Lin Changrong from China National Offshore Oil Corporation(CNOOC) is a recommended method for diagnosis of occlusion body in seismogenetic fault.Seismogenetic research must come out from the erroneous cognition of plate"extrusion".
