| 中文摘要: |
| 以某一实际工程为研究对象，研究施工控制与监测技术在大跨度钢结构桁架屋盖节点加固施工中的
具体应用，研究发现：加固施工过程对各测点的应力应变均有影响，但影响的程度与加固施工部位到测点的
距离有关，加固过程对结构的竖向位移也会产生不利影响，但是其影响程度不大；在施工过程中，将监测结
果与数值模拟分析结果相比较，发现两者的拟合程度较好。 |

| Taking a practical project as the research object，the application of construction control and monitoring technology
in the reinforcement of large-span steel structure truss roof joints is studied. The research finds that the reinforcement
construction process has an impact on the stress and strain of each measuring point，but it affects the degree of influence
is related to the distance from the reinforcement construction site to the measuring point. The reinforcement process
will also have an adverse effect on the vertical displacement of the structure，but the degree of influence is not
large. During the construction process，the monitoring results are compared with the results of numerical simulation analysis.
It is found that the fitting degree of the two is good. |
