摘要:
以河南省济(源)邵(原)高速公路王坑隧道为工程背景,利用ANSYS软件建立无超前小导管支护和有超前小导管超前支护两种工况下隧道三维有限元计算模型,通过隧道开挖模拟计算分析超前小导管对掌子面稳定性影响.计算结果表明:相对于无超前小导管工况,在有超前小导管工况下掌子面竖向的荷载和竖向应力以及掌子面水平方向位移都有一定程度的减少;改变超前小导管的环向分布范围和管径能够影响超前小导管的支护效果从而改善掌子面的受力情况.以上结果分析表明:超前小导管的存在增强了隧道掌子面的稳定性,使隧道的开挖过程更加安全.
Abstract:
Based on the result of shaking table test and Pushover analysis of SRC frame，the problem thatstrong column—weak beam failure mechanism is difficult to realize in practical composite flame is studied fromtwo aspects：the regulations incoordination on strong column—weak beam between reinforced concrete flameand steel frame and the seismic properties difference between steel beam and SRC column，basic defect anddeficiency of norm provision on internal force adjustment is demonstrated．Suggestions about internal force ad—justment coefficient for strong column-weak beam realization of composite flame and the imulation of SRCmembers are proposed．
