摘　　要：上海轨道交通11号线安亭支线区间隧道被京沪高铁工程施工临时PC桩击穿,致使该段区间上、下行线隧道管片均出现严重破损。对事故场地工程地质条件、管片损伤程度、工期等影响因素作具体分析后,提出了针对下行线区间隧道的"局部加固、局部替换"和针对上行线区间隧道的"冻结加固暗挖修复"的原位修复方案。实施结果证明修复效果良好。The temporary PC piles in express railway line project between Beijing and Shanghai were accidentally driven into the interval tunnels of branch line of Shanghai Metro Line 11 in Anting. And so the lining of the interval tunnels were badly damaged. Based on the analysis of the geological condition, extent of damage, construction time limit and etc., two rehabilitation programs in original tunnel position are suggested. One is ＂local reinforcement and local replacement＂ for left line, and the other is ＂subsurface excavation method after freezing＂ for right line. And the two rehabilitation programs are proved to be effective by practice.
