川西北倒三角形断块东部区域强震带形成机制与地震活动特征

川西北倒三角形断块东部区域地处青藏高原东部边缘地带,地跨川西北高原及其与四川盆地过渡带的高山峡谷区,属我国著名的南北向地震带的中段,因其特定的大地构造环境和强烈的现代地壳构造运动,导致其在强大的近东西向构造应力场的驱动和平卧“A”字型控震构造体系的控制下,沿两侧边界断裂向东强力楔入,于“构造急剧收口带”之西侧形成了一个近SN向地跨三大构造单元的强震带,强震沿该带有规律的往返迁移和重复发生,且地震活动强弱具有较明显的分形特征。

多年冻土区路桥过渡段的一种新结构

The design of roadbed-abutment transition part is always a challenging problem in transportation engineering, especially in permafrost distribution zone. A new type of roadbed-abutment transition part on permafrost was presented, and long-term observation was conducted for the deformation and the thermal regime of a roadbed-abutment transition part in the constructing Qinghai-Tibet Railway. In this paper, a new structure was presented and the observed settlements both in the subgrade and the base and its dependency with the thermal regime (permafrost table) were analyzed. In conclusion the roadbed-a-butment transition method for permafrost distribution zone was evaluated.     

Study on Ground Motion Attenuation Relation in Shanghai and Its Adjacent Region

Based on intensity data in Shanghai and its adjacent region, the intensity attenuation relation is determined. Selecting the western United States as a reference area where there are rich strong ground motion records and intensity data, and by determining ground motion attenuation relation in an area lacking in strong ground motion data, we obtain the ground motion attenuation relation in Shanghai and its adjacent region.     

Features of the M7.9 Earthquake in the Russia- Mongolia- China Boundary Region

At 19:33 p. m on September 27, 2003, an earthquake with M7.9 occurred in the RussiaMongolia-China boundary Region. It was strongly felt in the Altay region of Xinjiang. The losses caused by the earthquake was 76 million yuan (RMB). Some information about the earthquake was outlined, including basic parameters, focal mechanism, evaluation of earthquake disaster losses and so on. The satellite remote sensing information worked initial analysis for deformation of ground and failure phenomenon.

滇西北新生代逆冲推覆构造

滇西北地区新生代逆冲推覆构造较为发育，从西到东可分出走向NS、相互平行的4带：澜沧江带，云岭带，石钟山带和剑川-洱源带。其中，澜沧江带与云岭带组成对冲格局，云岭带又与石钟山带组成反冲格局，石钟山带与剑川-洱源带又组成对冲格局。参与逆冲推覆的地层主要是中生代三叠系、侏罗系、白垩系及新生代云龙组、宝相寺组，推覆体由石炭系、二叠系、上三叠统岩石组成。逆冲推覆时间为喜马拉雅期。
