Many scientists believe this link between temblors and dams—called reservoir-induced seismicity—may have been what happened at California's Oroville Dam, in the foothills of the Sierra Nevada.

许多科学家相信大坝和地震之间存在联系——这种联系称为水库诱发性地震活动——这可能就是在内华达山脚下的加洲Oroville大坝所发生的事情。

Design of a high-rise business-living building with double-tower structure with enlarged base ;2. Dynamic response analysis of an asymmetric two-tower tall storeyed building with enlarged base ;3. Based on the mode analysis and time-history analysis of two examples,the vibration characteristics of the connected twin-tower structures with enlarged base in vertical earthquake excitation was discussed in this paper,and the calculating results of the structures with or without connecter,both with enlarged base are compared.
