摘　　要：地下综合管廊在地震作用下,最易发生破坏的部位通常在角部且整体性也会受到一定程度的影响。实际工程中通常采用加腋和加减震层来提高管廊的抗震性能。基于ANSYS建立了三维有限元模型,系统论述了3种不同的管廊接头在设置加腋和减震层的情况下,地下综合管廊的动力响应。研究表明,适当的加腋高度能有效地解决管廊接头四壁的应力集中,而加腋和减震层的设置能有效降低管廊整体的应力水平。Under the action of earthquake,an underground utility tunnel is usually damaged at corners,which may influence the overall structure to a certain degree.Therefore,in practical construction,haunches and damping layers are added to improve the seismic performance of utility tunnel.In this paper,based on ANSYS,a three⁃dimensional finite element model was established to systematically analyze the dynamic response of underground utility tunnels that were respectively provided with three different joints with haunches and damping layers.The results show that,proper haunching height can efficiently solve the problem of stress concentration on four walls of utility tunnel joint,and haunches and damping layers can effectively reduce the overall stress level of utility tunnel.
