超越概率 meaning in English
probability of exceedance
Examples
- The research results indicate that the earthquake degree is 6 , considering the exceeding probability to be 10 percent in the future 50 years
本次工作通过地震危险性分析得到50年10超越概率时地震计算烈度为6 . 0度。 - The combined effect of the soil , structure and seismic wave was considered in the analysis and the time - dependant curves of earthquake - induced differential settlement of the building were obtained according to differential probability of seismic ground motion
考虑了土层、建筑物荷载分配、地震动波形等影响因素对不均匀震陷的协同作用效果，依据不同超越概率下的地震动给出了建筑物不均匀震陷时程曲线。 - According to the need of design code for anti - seismic of engineering constructure , the bedrock peak acceleration rate and response spectrum of exceeding probability of 63 % , 10 % and 2 % are given respectively and seismic motion parameters are also calculated , which will provide the evidences for anti - seismic design of this electric power equipment station
按工程建筑物抗震设计规范要求，分别给出了50年63 % 、 10 %和2 %超越概率水平的基岩峰值加速度及反应谱，计算出地震动参数，为该电力设备站建设提供了抗震设计依据。 - The vulnerability evaluation procedure of hazus99 which is widely adopted in the united states and world wide is introduced in briefly . then the general technical frame of the first part is illuminated as follows : by means of the form of hazus99 , the earthquake action is expressed by demand spectra and the capacity of buildings is described by capacity curve
在此基础上，本文叙述了“吸收hazus99的表达形式，以需求谱来表达地震作用、抗力曲线表达结构的抗震能力，用需求谱和抗力曲线的交点确定的谱位移和各个震害等级对应的谱位移均值和标准差一起，分别计算建筑物对应各个震害等级的超越概率，获得易损性曲线”的一套完整的技术思路。 - Present methods generally based on the statistics of earthquake damage , expert experiences , theory analysis and experimental researches have obvious advantages , disadvantages and certain scopes of application ; ( 2 ) different prediction methods should be adopted against different building conditions , sites , intensity and experiences etc to predict earthquake damage of buildings for prospective accuracy , dependability and availability ; ( 3 ) earthquake damage matrix , which is the foundation of earthquake damage prediction , of 7 kinds of building in the urban areas of zhangzhou city under intensity 6 to 9 has been set up . the damage conditions of different buildings under different intensity are as followings : all kinds of structures are basically intact under intensity 6 ; the reinforced concrete structures are basically intact under intensity 7 , but other kinds of structures are destroyed slightly ; the reinforced concrete structures are still basically intact while other kinds of structures are destroyed intermediately under intensity 8 ; the reinforced concrete structures are destroyed slightly , single - story factories and open houses are destroyed intermediately and other kinds of structures are destroyed seriously under intensity 9 ; ( 4 ) the results of earthquake damage predicting of buildings embody the damage when earthquake happens in the future . thus , further identifications and reinforcements should be considered to buildings that will be destroyed intermediately or more under the earthquake with 10 % exceeding probability in future 50 years ; ( 5 ) the direct economic losses caused by damage of buildings resting with the area , structural type , intensity and damage of all kinds of buildings are the main part of the losses of the city in an earthquake ; ( 6 ) the direct economic losses increased progressively toward high intensity by 2 or 3 times
基于上述研究，得出的主要结论有：建筑物震害预测是一个模糊的、系统的、复杂的问题，现有的方法很多一般都是以震害统计规律、专家经验、理论分析和试验研究为依据，有其自身的优缺点和一定的适用范围；应针对不同的建筑物条件、场地条件、地震强度和已有经验等，采用不同的预测方法进行建筑物震害预测，以使预测结果达到预期的精确性、可靠性和可操作性；建立了漳州市区7类建筑物在6度9度地震作用下的震害矩阵，成为指导抗震防灾的重要依据，各类结构的震害情况表现为： 6度地震作用下各类建筑物基本完好； 7度地震作用下除钢筋混凝土结构基本完好外其余以建筑轻微破坏为主； 8度地震作用下钢筋混凝土结构仍以基本完好为主而其余建筑以中等破坏为主； 9度地震作用下钢筋混凝土结构以轻微破坏为主，单层工业厂房和空旷房屋以中等破坏为主，其余建筑以严重破坏为主；建筑物的震害预测结果体现了未来地震来临时的震害程度，在编制漳州市区抗震防灾规划时，对于遭遇50年超越概率10的地震影响发生中等以上破坏的建筑物应考虑进行抗震鉴定和加固；由建筑物的破坏所造成的直接经济损失是城市地震经济损失的主要部分，重庆大学硕士学位论文中文摘要其主要与建筑物总面积、结构类型、地震烈度和各类建筑物的震害程度有关;不同烈度造成的直接经济损失按2一3倍向高烈度方向递增，漳州市区直接经济损失由6度至9度的比例关系为1 : 2 . 8 : 8 . 6 : 22 . 8 ;遭遇基本地震设防烈度( 7度)时，漳州市区直接经济损失约4 . 5亿元，无家可归人员约40000人，且以砖木结构和多层砖混结构的震害损失最大;地震造成的人员伤亡主要与建筑物倒塌及严重破坏的程度和总面积以及震时的建筑物室内人数密切相关，地震时无家可归人员主要与住宅倒塌、严重破坏及中等破坏的程度和总面积以及城市人均居住面积密切相关。
