【摘要】：近年来,伴随着科技进步与经济发展,建筑领域内设计与施工工艺都取得了飞跃性的进步。人们在保证建筑的使用功能和安全性能的基础上,开始追求异性建筑和建筑的多功能性。大跨度悬挑结构作为一种具有代表性的结构,越来越多的在实际工程中的得到应用。大跨度悬挑结构一般规模巨大。由于其结构的复杂性,使得施工周期长,力的传递路径在构件内不确定以及构件受力具有明显的动态性。这给施工过程提出了更高的要求。为保证施工过程顺利进行,对结构进行全面准确的施工监测是十分必要的。本文以渡江战役纪念馆工程为依托,拟开展下列研究：1、建筑物沉降和整体垂直度的监测；2、对整个建筑物外观的倾斜度进行实时监控,及时纠偏,防止建筑物外观与建筑设计立面效果有偏差；3、关键部位的应力、应变,以及位移与变形；(1)对上部型钢混凝土拉杆的拉应变和应力进行实时监控,防止在施工过程中拉杆被拉裂以及防止拉杆变形过大,保证拉杆应力满足设计要求；(2)对下部型钢混凝土压杆的拉压应变进行实时监控,以防在施工过程中大桁架梁根部弯矩对此杆件造成局部开裂以及屈服现象；4、大跨度混凝土梁施工期间的变形监测及控制；5、通过对脚手架现场实测数据,并结合数值、理论计算结果,掌握脚手架结构受力状态,判别脚手架结构的稳定性,并做出可靠的预测,提出防止在施工过程中出现脚手架坍塌、滑移,出现不必要的各种安全隐患的措施.
[Abstract]:In recent years, with the development of science and technology and economic development, the design and construction technology in the field of architecture has made great progress. Began to pursue heterosexual architecture and the versatility of architecture. Long span cantilevered structures as a representative structure, More and more applications have been made in practical projects. Large span cantilevered structures are generally large in scale. Because of the complexity of their structures, the construction period is long. The transmission path of the force is uncertain in the component and the force of the member is obviously dynamic, which puts forward higher requirements for the construction process, in order to ensure the smooth progress of the construction process, It is necessary to carry out comprehensive and accurate construction monitoring of the structure. It is proposed to carry out the following research: 1: 1, monitoring building settlement and overall perpendicularity in order to monitor the inclination of the whole building's appearance in real time, correct the deviation in time, prevent the deviation between the appearance of the building and the effect of the facade of the architectural design, and prevent the stress in the key position. The strain, displacement and deformation can be used to monitor the tension strain and stress of the upper steel reinforced concrete rod in real time, to prevent the tension rod from being cracked and to prevent the rod from deforming too much during the construction. To ensure that the stress of the strut meets the design requirements.) the tension and compression strain of the lower section steel reinforced concrete compression bar is monitored in real time. In case of local cracking and yielding phenomenon caused by the bending moment at the root of large truss beam during construction, the deformation monitoring and control of long span concrete beam during construction is 5. Through the field measured data of scaffold and combined with numerical value, Theoretical calculation results, grasp the stress state of scaffolding structure, judge the stability of scaffold structure, make reliable prediction, and put forward the measures to prevent scaffold collapse, slip and unnecessary safety hidden trouble in the construction process.
