摘　　要：基于武汉地铁3号线王宗区间隧道和龙阳大道高架桥平行施工情况,对紧邻地铁隧道的高架桥桥台桩基施工过程进行数值模拟分析,研究龙阳大道立交桥桥台桩基施工对已完成初期支护的地铁区间矿山法隧道初支结构可能产生的影响,并采取隧道结构的保护措施,保证了高架桥桥台桩基施工和邻近地铁区间隧道的安全。Based on the concurrent construction situation of mining tunnel of Wangzong Section of Wuhan Metro Line 3 and viaduct of Longyang Road,a numerical simulation on the whole construction process of abutment pile foundations of viaduct near the metro tunnel was carried out to identify the influence of abutment pile foundation construction for viaduct of Longyang Road on the initial support structure of metro mining tunnel with initial support completed. And appropriate protection and control measures were taken for the tunnel structure to meet safety requirement of concurrent construction of the viaduct abutment pile foundation and the metro mining tunnel.
