| 摘 要： | 在顶升纠偏技术中,运用空间桁架理论,托换结构可以简化为拉一压杆模型。文章通过试验研究分析,考虑了原来的支撑体系发生变化的危害,分析了三角形式支撑和四角形式支撑时承载力大小和结构破坏形式的不同。文中指出三角形式支撑易发生对角线对折的脆性破坏受力形式对承台的受力极为不利,为设计和施工提供了有价值的参考。

| Abstract: | Theory of spatial truss model is used for lifting pin in correcting engineering.Underpinning structure can be simplified strut-and-tie model.By means of experimental study and considering the damaging of changed support system,the difference of quadrilateral and tripod system had been analyzed in bearing capacity and destructive model in the paper.The paper also pointed out the disadvantage in tripod system is obvious for the brittle failure.It is valuable reference for design and execution of works. |
