| | The development of the computer program series of earthquake resistance engineering designs, ERED-01, has been carried out since 1987 in the Institute of Earthquake Engineering in accordance with the newly issued Building Seismic Design Code. The Series/ERED-01 completed at the first stage, which makes the latest achievements of the research and design in earthquake engineering code-matching, systematic and microcomputer-useful, consists of twelve programs, dealing with the following main fields... | | 为配合新规范的颁布和促进新规范在全国的推广应用,工程抗震研究所于1987年开始了工程抗震设计软件系列ERED的研制工作。将工程抗震研究和设计工作中的最新研究成果规范化、系列化、微机化。本文主要介绍第一阶段已完成的ERED-01系列12个应用程序。主要程序涉及:时程法抗震设计时地震波的选用及人工地震波的产生、地震危险性分析和设计地震动参数场址动力反应分析、各类结构抗震设计平面结构的时程法分析、大震作用下结构弹塑性地震反应与抗倒塌的薄弱层抗震变形验算等方面。这些程序已在国内一些设计和研究单位推广使用。 | | 文摘来源 | | The peak acceleration of ground motion will surely provide important ba- ses for long-term city planning and earthquake strategy and is also the basic parameter of seismic design for a project. Based on the study of regional seismic environment and seismic periodicity, the potential seismic source zones and their activity parameters are determined. The whole city area is divided into regular retwork and the probability level of seismic risk at each joint in different period is ... | | 工程场地地面运动峰值加速度是强震区城市发展规划、抗震防灾的重要依据,也是工程建筑抗震设计的基本参数。本文在研究秦皇岛市区域地震地质环境和地震活动规律的基础上,确定了区域潜在震源区及相应的地震活动性参数。将该市工程场地划分为规则网格,采用地震危险性分析的概率方法,计算出各场地在各不同年限内所遭受到的不同地震危险性概率水平。最后,编制出了供一般工业与民用建筑设计使用的,按50年10%给定概率水平的秦皇岛市地面运动加速度预测图。 | | 文摘来源 | | In this paper, the authors have summarized the kinematic and dynamic character of seismic wave observed by downhole equipment in our country. Seismic wave amplitude, travel time, spectrum and wave field are discussed respectively on ground and downhole, in soil layer and rock layer, and explained unifiedly by softly covered layer effects. This research achievement has been used in building seismic stations, analyzing data, locating fracture in oil field and determining parameters of ... | | 本文系统地总结了我国深井观测地震波的运动学和动力学特征,即从地面与井下以及土层与岩层,分别就地震波振幅、走时、频谱、波场等方面做了讨论,并用软盖层效应加以统一解释。本成果已在台站建设、资料分析、震源参数测定、油田裂缝定位和介质结构参数测定等方面发挥了作用。 | | 文摘来源 | |   | | << 更多相关文摘 |
