秦岭北缘断裂带为秦岭山地和渭河盆地的分界断裂, 是一条全新世以来多次活动的活动性区域断裂. 某输水工程拟定的两个线路方案与该断裂周至—长安段走向近一致, 距离较近, 断裂带对选线影响较大. 在详细描述周至—长安秦岭北缘断裂带特征的基础上, 结合勘探成果, 对拟定两个线路方案进行了影响评价, 得出了隧洞方案受断裂影响较小的结论.
秦嶺北緣斷裂帶為秦嶺山地和渭河盆地的分界斷裂, 是一條全新世以來多次活動的活動性區域斷裂. 某輸水工程擬定的兩箇線路方案與該斷裂週至—長安段走嚮近一緻, 距離較近, 斷裂帶對選線影響較大. 在詳細描述週至—長安秦嶺北緣斷裂帶特徵的基礎上, 結閤勘探成果, 對擬定兩箇線路方案進行瞭影響評價, 得齣瞭隧洞方案受斷裂影響較小的結論.

The fault zone in the northern margin of Qinling Mountains is a boundary fault between the Qinling mountain -ous region and the Weihe basin which is an active regional fracture since Holocene .The proposed two line plans of this water conveyance project are parallel and near to the fault zone from Zhouzhi to Changan section ,which has a greater im-pact on the line section .Combining exploration results ,the paper describes characteristics of the fault zone in the northern margin of Qinling Mountains in detail and carries out the assessment of impact of the proposed two line plans ,concludes that tunnel scheme is less affected by the fault zone .
