| 摘 要： | 文章用配筋等效法模拟钢支撑对喷混凝土的加强作用,并根据《铁路工程设计技术手册——隧道》中的钢筋混凝土配筋计算公式推导出初期支护与二次衬砌的安全系数计算公式,以此为基础算出不同支护方案所能承受的极限荷载,再结合隧道岩溶段的实际情况选择支护参数。

| Abstract: | The reinforcement of shotcrete with steel struts is simulated using the equivalent method of reinforcement bars,and a calculation for the safety factor of the primary support and secondary lining is derived based on the formula for concrete reinforcement bar given in Manual of Railway Engineering Design-tunnel. The ultimate bearing capacities under different support parameters are calculated.Support parameters are selected by taking the actual condition of the Karst section of a tunnel into consideration. |
