摘　　要：将盾构出洞冻结法加固拱形结构近似为单心固定无铰拱模型,并对模型进行内力计算和验算,验证了无铰拱模型是该类工程一种可行的计算简化模型,为类似工程设计提供参考。The arch shed structure reinforced by freezing whose shield is unkenneling is approximated to a one-centered model reinforced without reamed arch. The inner force of this model is calculated and checked, which shows this model is a feasible and simplified calculation model and supplies reference to the similar project designs.
