| 摘 要： | 预应力锚杆柔性支护已逐渐在深基坑工程中得到广泛应用,其主要构件之一锚下承载结构的破坏模式与设计计算尚不明确。结合工程实例对锚下承载结构的各个组件进行详细阐述,然后通过有限元模拟计算。针对不同的预加应力,首次对槽钢、垫板、加劲肋钢筋、喷射混凝土等构件之间的选型尺寸进行了探讨,提出了各个构件之间合理的匹配关系,为相关人员在设计锚下承载结构时提供参考。

| Abstract: | The prestressed anchor flexible supporting system has been widely used in the deep foundation pit.As one of the main components to prestressed anchor flexible supporting system,the failure mode and design calculation of bearing structure under anchorage are unclear.Based on an engineering example,the component members of bearing structure under anchorage have been analyzed.By finite element simulation calculation,the type selection among channels,plate,stiffener reinforced rebar and shotcrete have been anal... |
