摘要:早期建设的大型体育场馆面临着结构耐久性已达安全使用下限、系统的设备升级改造、人流疏导与现代交通系统接驳、文化消费提升等问题,需要拆除复建。以北京工人体育场拆除施工为例,比选了爆破拆除、静力拆除、机械拆除3种方案,最终采取机械拆除方案;通过有限元软件MIDAS Gen对3种不同拆除工况采取移除构件法进行拆除施工仿真计算,结果表明采取从高到低、逐跨逐间、先内后外的拆除工况最为合理;并对该种工况选取3个不同步骤进行连续倒塌分析,描述了预应力梭形灯架、钢结构挑梁、主体看台区的拆除施工工艺,为北京工人体育场拆除施工提供技术支撑。

Abstract: The large stadiums built in the early days are faced with problems such as the structural durability has reached the lower limit of safe use, the upgrading and transformation of the system equipment, the connection between the flow of people and the modern transportation system, and the promotion of cultural consumption, which need to be demolished and rebuilt. Taking the demolition construction of Beijing Workers Stadium as an example, three schemes of blasting demolition, static demolition and mechanical demolition were compared and selected, and the mechanical demolition scheme was adopted finally. The removal of components method were adopted to carry out the demolition construction simulation calculation for three different demolition conditions by finite element software MIDAS Gen. The results show that the demolition conditions from high to low, span by span, first inside and then outside are the most reasonable. Three different steps were selected for continuous collapse analysis in this condition, and the demolition construction technology of prestressed spindle light frame, steel structure beam and main stand area were described, which provides technical support for the demolition construction of Beijing Workers Stadium.
Keywords: Beijing Workers Stadium; large stadium; mechanical demolition; construction simulation calculation
