三维前方交会在大型金属网架结构中的应用

The application of 3D forward intersection in large-scale metal truss structures

探讨了三维前方交会法在大型无支撑金属网架结构屋面施工的质量监测方法,并对实测数据进行了分析,结果表明该方法保证施工质量,达到设计要求,为今后的安全运营提供了可靠的依据。同时为大型无支撑建筑屋顶的变形监测提供了一种测量监测依据。

This paper discussed the quantity monitoring methed of 3D forward intersection in large-scale metal truss structure＇s roof, through this method the quality of construction survey can beensured, the design request can be attained, this method also provides feasible survey data for the future actual application. It simultaneously provides the monitoring data for deformation monitoring of large-scale metal truss structure＇ s roof.
