Electric power system is fundamental for social production and daily life. Especially in urban areas, electric power network has been a key infrastructure of the lifeline, and its failure will probably paralyze the whole city. On the other hand, as population growth and urbanization, the demand for electricity is overwhelmingly increasing. Electric power network is getting larger and more complex. Meanwhile, modern electric power network is unprecedented vulnerable and modern society is faced with higher blackout risk. In order to effectively prevent blackout risk and rapidly response the blackout accident, emergency management of electric power system are responsible for preparedness, mitigation, response, and recovery of its failure. Blackout is one of the most severe accidents in electric power system failure, and is paid great attention all the time. In recent decades, many techniques have been developed for effective prevention and control of blackout. This paper analyzes the core requirements and major challenges of prevention and response of blackout. And then, some potential advanced techniques on planning, monitoring and early-warning, emergency response, etc. are introduced in view of latest research progress.","PeriodicalId":6302,"journal":{"name":"2010 International Conference on E-Product E-Service and E-Entertainment","volume":"38 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80610901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stress path in soil element under the load moving line was analyzed. It is found that the stress state changes from pure shear to triaxial shear and back to pure shear finally in one cycle. According to the stress path curves for different moving speeds, it is found that when the moving load is high, the maximum deviator stress decreases, but the horizontal shear stress increases dramatically. The stress path curves in soil element at different depth for both a low speed and a high speed (near to the Rayleigh wave speed) were presented. It is shown that horizontal shear stress and deviator stress increase first with the depth's increasing and decreases after reaching the maximum value. The shape of stress path curves at different depth is close for a low speed but differs greatly for a high speed and the soil element at shallow depth is mainly in a tensile state. The stress paths for different initial stress states were also presented. And it is found that the initial stress state influents stress path greatly. The bigger the initial deviator stress is, the more unobvious the variation of stress state and the principal stress axes rotation are.","PeriodicalId":6302,"journal":{"name":"2010 International Conference on E-Product E-Service and E-Entertainment","volume":"5 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90687711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
