查询词典 earthquake

The results of rupture landform investigation indicate that this fault is one of weak active faults in Holocene, its average vertical slip rate is 0.5~0.6mm/a. On Jun. 15, 1975, Liuba M6.2 earthquake in Kangding occurred on the fault. The macro-epicenter located at Shuobu-Moda, Liuba county. The direction of long axis of meizoseismal area is same as that of Yunongxi fault trend. The occurrence of the earthquake is resulted from the newest activity of the fault.

How to ensure this new structure to be in elastic state under frequent earthqu ake, be mendable under design earthquake and not collapse under infrequent earthquake, especially the last item, is the problem to be solved imminently in engineering field. Center around this problem, 5 aspects of investigation are carried out as following:(1) The experiment of seismic performance of ASCCs in this new frame structure has not been reported, in order to study this problem, 9 ASCC specimens with shear steel plate are tested subjected to the horizontal low cyclic loading, in which, the shear span ratio is 3 and axial compression ratio is different. The hysteretic curves of 9 specimens are obtained. The seismic performance indexes such as energy dissipation, stiffness degradation, strength degradation, skeleton curves and ductility of this kind of column are acquired, and the seismic fortification measures including ultimate values of axial compression ratio under different seismic degree are suggested.

1新型框架结构中所采用的角钢混凝土柱抗震性能的试验研究尚未见报道，针对这一问题，本文进行了9根剪跨比为3、不同轴压比、采用钢板箍的角钢混凝土柱在水平低周反复荷载作用下的试验研究，获得了9根试验柱的滞回曲线，考察了该类柱的耗能、刚度退化、抗力衰减、骨架曲线及延性等抗震性能指标，建议了角钢混凝土柱在不同抗震等级下的轴压比限值等抗震构造措施。

There, they find that the anomalous groups are variety,similarity and periodicity of development before and after Baotou Ms 6. 4 earthquake, this is similar to Haicheng and Tangshan earthquakes, however, the obviously difference is that the abnormal is no causality and associated relation but paragenic relation with Baotou earthquake. They think the circum --B...

该区异常群体具有种类的多样性、配套性，在包头6.4级地震前后有发展阶段性，虽与海城、唐山地震前确有相似之处，但也有明显不同，认为环渤海地区参与了1996年以包头地震为代表的华北整体性构造活动，该区异常与包头地震无因果或伴生关系，而是共生关系，该区目前仍存在发生5～6级或6级以上地震的危险性。

Shear-wave splitting does not indicate potential earthquake locations, but analysis of local seismicity by Ragnar Stefánsson correctly predicted the small fault on which the stress-forecast earthquake occurred.

剪切波爆裂并不表示潜在的地震的位置，但Ragnar Stefansson对当地地震活动性的分析正确的预测应力预测的地震发生的小断层。
