摘要
以某重大交通枢纽项目典型环形钢筋混凝土支撑为例,对环形支撑拆除施工过程中的技术进行分析,介绍了此交通枢纽工程基坑的复杂情况及拆除施工时的不利影响,对施工中与设计要求不一致的工况进行统计分析,选择并建立了合适的有限元结构模型,计算环形支撑内力情况,验算其安全性能,最终达到了指导支撑拆除施工、缩短施工周期的目的。
Taking a typical circular reinforced concrete support of one major transport hub project as an example,technical analysis was carried out on circular support demolition.The complex condition of the foundation pit of the transport hub project and adverse impact of demolition were introduced,and statistical analysis was conducted on the inconsistency between construction and design requirements.A suitable finite element structure model was chosen and built,the internal force of the circular support was calculated,and the safety performance of the circular support was verified,thereby finally guiding support demolition and shortening the construction period.
