摘要
通过建立某风井的无内撑圆筒型围护结构GTS有限元模型,模拟了施工过程中结构的受力状态及位移水平,围护结构接缝位置采用弱化刚度的方式,较好地模拟了接缝的传力状态,并根据仿真施工过程得到的位移、应力等进行了分析,阐述此类型围护结构的空间受力性能较好,可为其他类似工程提供参考。
In this article,MidasGTS analysis models are created for a non-supported round air shaft to simulate the structure＇s stress and displacement upon construction process.In order to simulate the mechanical performance of the shaft＇s bracing structure,weaken stiffness technique is used in segment joint.By studying the displacement and stress condition on construction process,we illustrate the preferable spatial mechanical behaviors for this kind of bracing structure.It can be referred to the similar project of bracing structure.
