New Progress in LURR-Integrating with the Dimensional Method

摘要: The evolution laws of LURR (Loading–Unloading Response Ratio) before strong earthquakes, especially the peak point LURR, are described in this paper. results four methods (experimental, numerical simulation, seismic data analysis and with damage mechanics analysis) lead to a consistent conclusion—the earthquakes that, at early stage cycle, will fluctuate around 1 late stage, it rises swiftly its point. At some time after point, catastrophic event or events occur. These do not occur but lag behind. which is denoted by T2 depends on magnitude M upcoming earthquake among other factors. In order consider influence geophysical parameters specific region such as \( \dot{\gamma }, \)Ea J(t), where } \) shear strain rate tectonic loading situ, Ea sum radiated energy all occurring measured during long duration (110 years paper) divided area duration, J(t) parameter denoting anomaly weighted Y (the value LURR) represents expanse degree seismogenic zone. dimensional method has been used reveal relation between M, situ for more reliable prediction.
