仿真技术与地震工程
|
摘要
系统仿真是以系统科学、相似技术、信息技术与应用领域有关的专业技术为基础,以计算机和专用物理效应设备为工具,利用系统模型对真实或设想中的系统进行动态研究的一门多学科的综合性技术。它具有可行、安全、经济、方便等特点,因而在许多领域得到了广泛地应用。由于强烈地震的罕遇性、突发性、瞬时性、破坏性和复杂性,观测、试验和分析等方法在实际应用中受到了一些限制。仿真方法能够解决一些其他方法不易解决的问题,可以作为上述方法的有益补充。分析了仿真技术在地震工程中应用的必要性和可行性,并对其适用问题和应用前景进行了简要的说明。
Simulation is a multidisciplinary integrated technology based on system science,similarity technology,information technology and specialized technologies of application fields.Using computer and special physical devices as tools,it utilizes system model to research the characters of a system.For features such as feasibility,economization,safety and convenience,it gains extensive application in many fields,being one of major research methods for engineering and non-engineering.Because of features of strong earthquake,observation,experiment and analysis are restricted in some cases.Simulation technology,being a helpful reinforcement,can deal with some problems more effectively than methods above.In this paper,the necessity and feasibility of applying simulation technology to earthquake engineering are discussed. In addition,some applicable problems and applied prospect of simulation technology are stated.
