【摘要】 南水北调中线工程总干渠(陶岔—漳河段)从南至北穿越河南省17个市县,长708km,沿途横跨江淮黄海四大水系的大小河流350余条,经过地层主要有第四系、新近系、石炭系、二叠系、寒武系,并经过地震烈度7～8度区,会遇到膨胀土、湿陷性黄土、渠道渗漏、渠道稳定性等重地质灾害的威胁。同时,太行山前的水石流灾害、黄淮海流域的水污染灾害等,也将对南水北调中线工程总干渠的运行产生影响。沿途膨胀土将危害渠道边坡稳定性;湿陷性黄土将影响渠道的安全运行;渠道渗漏易产生大面积土壤盐渍化;区域稳定性和采矿塌陷将影响渠道的稳定性等。更多还原

【Abstract】 The main canal of middle route project(Taoca-Zhanghe section)of south-to-north water transfer is cross 17 county and cities of Henan province.The length is 708 km,and it will cross four great river systems,namely the Changjiang River,the Yellow River,the Huai River,and the Haihe river,including more than 350 great and small rivers.Meanwhile,it will cross many geological strata such as the Fourth Department,the Neogene,the Carboniferous,the Permian and the Cambrian,pass through areas with 7～8 degrees of earthquake intensity,and meet to expansive soil,collapse loess,outlet leaking,and so on.This paper discussed the possi-ble geological disasters that the canal might be happened,providing scientific references for the construction of the canal.更多还原
