摘要
采用Robot有限元软件分析了地下综合管廊的受力情况,对比承载力控制及裂缝控制下的管廊配筋,提出地下综合管廊的配筋设计的控制要点。研究表明:当管廊还未达到承载能力极限状态时,裂缝已无法满足正常使用极限状态下的要求。故管廊的配筋主要由正常使用极限状态下的裂缝控制,并满足抗震构造要求。
Through the method of Robot Finite element analysis,the force condition of underground pipe gallery is studied.The control points of the reinforcement design of the underground pipe gallery are proposed by comparing the control of bearing capacity and the cracks.Results show that the cracks of the pipe gallery are unable to meet the requirement of normal service conditions before reaching the limit of bearing capacity.So that the reinforcement of the pipe gallery is mainly controlled by the cracks under normal service conditions,and the earthquake construction requirements should be met.
