质量树分析在龙形溪大桥中的应用

Analyze and establish the quality tree of Long Xinxi super bridge

为了更好的确保沪昆高铁长昆湖南段龙形溪大桥的施工质量,针对该桥在施工期间可能遇到的质量问题以及相关因素进行分析梳理,并用树型图表示,建立龙形溪大桥质量树模型图,即QTA分析法;同时根据实际情况,以及工程经验确定可能产生的各种质量问题情况以及各自发生概率,进而有可能定性与定量的判定各作业工序对桥梁质量的影响程度,以此实现对桥梁施工质量的把握和控制,为桥梁质量控制提供依据和数据。

In order to guarantee the construction quality of Long Xinxi super bridge,analyze the related factors which are likely occurred during the process of construction,and use tree model to express it,that is use QTA method to establish the quality tree model,at the same time ascertain the probability of all kinds of problems,then judge the influence degree by qualitative and quantitative method,thus could control the construction quality,provided basis for construction quality of the bridge.
