The characteristics and mechanism of earthquake disasters on permafrost sites induced by the west of Kunlun Mountaion Pass 8.1 earthquake in 2001
The West of Kunlun Mountain Pass Ms8.1 earthquake in 2001 on the Qinhai-Tibet plateau is one of largest earthquakes in the permafrost regions on the globe. This earthquake event caused the ground surface rupture zone having the length of 426 km with the ground fissures about 10-30cm wide, seismic subsidence up to the maxium value of 20 cm. Moreover, the earthquake triggered liquefactions along shores of lakes and banks of rivers, landslides of a dam and collapse of slopes, and avalanches. The characteristics of the earthquake disasters were studied through on-site investigation, geophysical survey， laboratory tests of the soil samples and numerical analysis of the dynamic behaviors. Furthermore, the relevant prevention measures for engineering projects were proposed which would provide valuable scientific basis for earthquake disaster mitigation in cold regions.
期刊介绍：
Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere.
Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost.
Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
