桥梁结构检测分析系统研究

Bridge Test Analysis System Study

桥梁结构检测分析系统QLJC是针对桥梁检测试验分析开发的专用软件,能够建立桥梁结构空间有限元模型,运用实体单元法和空间梁格法进行静动力试验分析、试验荷载效率计算,查取测点位置理论计算值等。该系统是桥梁检测工作的辅助工具,也可用于分析宽、弯、斜桥梁结构空间受力状态。本文详细介绍该系统的整体构思、特点、计算原理以及实桥应用算例等。

Analysis System for Bridge Test (QLJC in Chinese) is an application software specially designed for bridge test to build spatial FEM model of bridge structure with beam elements or solid elements,analyze the static and dynamic character of bridge structures,calculate efficiency ratio of load test,pick up the results of observation points and so on.QLJC is a tool not only for bridge test but also for spatial analysis of wide,curved and skew bridge.In this paper,research content,system design,calculation theory,characteristics and practical application of QLJC is introduced in detail.
