摘要
结合某在役大型石拱渡槽工程实例,在借鉴桥梁结构及类水工建筑物评价的基础上,依据石拱渡槽结构自身特点,运用现场检测分析、静力分析、动力分析三位一体的分析方法,对该在役大型石拱渡槽工程安全性及病害机理进行了全面综合分析,并给出了有针对性的病害治理方案。指出:结合石拱渡槽结构特点全面布置检测与数值模拟分析相结合的全新检测分析评价方案,可从整体到局部、外部到内部充分分析渡槽病害产生的机理,对石拱类渡槽具有普遍适用性。
Based on the evaluation of bridge structure and similar hydraulic structures and the characteristics of stone arch aqueduct structure,the safety and disease mechanism of a large⁃scale stone arch aqueduct in service were studied by using the trinity analysis method of field test analysis,static analysis and dynamic analysis.A comprehensive and inclusive analysis was conducted.It is pointed out that the structural a⁃nalysis and the evaluation plan of the stone arch aqueduct,which combining comprehensive testing with numerical simulation analysis,can fully analyze the aqueduct disease generation mechanism from the whole to the local and from the external to the internal.This method has u⁃niversal applicability to stone arch aqueducts.
