“十五”期间,中国地震局为满足地震应急现场通信的需要,为各省地震局配备了卫星通信便携站.青海省地震局地震应急卫星通信车是在原有箱式卫星便携站的基础上进行了改进,将便携站的全套设备安装于改装后的依维柯厢式货车内,天线部分做了车顶安装.经过上述处理后,该车具备了移动通信车的优点,有力提升了地震现场应急的通信保障及指挥协调能力.在简述应急卫星通信车通信系统的功能基础上,详细对实际应用中出现的问题进行了总结,并对将来应急通信车通信系统的进一步完善进行了探讨.  相似文献   

某核电厂应急指挥中心基础隔震研究     

范世凯  谭平  刘德稳  周福霖 《华南地震》2014,(1):80-85

应急指挥中心是核电厂应为紧急核事故而专设的指挥中心,本文对某核电厂应急指挥中心进行基础隔震设计,分析了隔震效果;建立了各楼层的楼层反应谱,对比分析了隔震前后结构楼层反应谱与目标反应谱的关系。结果表明,隔震后结构明显降低了应急指挥中心的地震反应,同时,其楼层反应谱也大大降低,确保核电厂应急指挥中心在应急抢险中充分发挥其功能作用。  相似文献   

Two-dimensional finite volume method for dam-break flow simulation   总被引：2，自引：0，他引：2  

M. ALIPARAST 《国际泥沙研究》2009,24(1):99-107

A numerical model based upon a second-order upwind ceil-center f＇mite volume method on unstructured triangular grids is developed for solving shallow water equations. The assumption of a small depth downstream instead of a dry bed situation changes the wave structure and the propagation speed of the front which leads to incorrect results. The use of Harten-Lax-vau Leer （HLL） allows handling of wet/dry treatment. By usage of the HLL approximate Riemann solver, also it make possible to handle discontinuous solutions. As the assumption of a very small depth downstream oftbe dam can change the nature of the dam break flow problem which leads to incorrect results, the HLL approximate Riemann solver is used for the computation of inviscid flux functions, which makes it possible to handle discontinuous solutions. A multidimensional slope-limiting technique is applied to achieve second-order spatial accuracy and to prevent spurious oscillations. To alleviate the problems associated with numerical instabilities due to small water depths near a wet/dry boundary, the friction source terms are treated in a fully implicit way. A third-order Runge-Kutta method is used for the time integration of semi-discrete equations. The developed numerical model has been applied to several test cases as well as to real flows. The tests are tested in two cases： oblique hydraulic jump and experimental dam break in converging-diverging flume. Numerical tests proved the robustness and accuracy of the model. The model has been applied for simulation of dam break analysis of Torogh in Iran. And finally the results have been used in preparing EAP （Emergency Action Plan）.  相似文献   

Post-earthquake emergency assessment of building damage, safety and usability—Part 2: Organisation     

S.  M.   《Soil Dynamics and Earthquake Engineering》2008,28(3):233-244

The purpose of this paper is to describe the organisational aspects of the planning, setting up and execution of building inspection operations under emergency conditions, created by damaging earthquakes. The procedures developed herein reflect experience from damaging earthquakes in Greece and elsewhere and were tested in a pilot trial in the Greek city of Chania, with the purpose of adapting them in the overall earthquake emergency response plan of Greece. A computer program, PEADAB (for Post-Earthquake Assessment of Damaged Buildings) has been developed to support the planning and execution of such operations. Technical aspects of the operation are described in a companion paper (Part 1).  相似文献
