摘　　要：为探究盾构隧道施工扰动所引起的导水裂隙带发育高度变化情况,依托深圳13号线留仙洞站-白芒站区间工程,提出一种导水裂隙带发育高度预测计算方法,确定留白区间导水裂隙带发育高度为22m,盾构施工引起的导水裂隙带高度不会波及上覆水体底部,对引水隧道的结构安全和盾构施工进度影响较小。This paper investigated the variation of the development height of the water diversion fissure zone caused by the construction disturbance of the shield tunnel.Based on the section project between Liuxiandong station and Baimang station of Shenzhen line 13,a prediction and calculation method for the development height of the water di⁃version fissure zone is proposed.It is determined that the development height of the water diversion fissure zone in the left white section is 22 m,and the height of the water diversion fissure zone caused by the shield construction will not affect the bottom of the overlying water body,which has little impact on the structural safety of the diversion tunnel and the shield construction progress.
