摘要
为查明武威市丰乐镇一带浅部岩性分层、水体赋存及构造展布等情况,通过布设一条高密度电法长剖面,初步查明区内浅部松散沉积层的地电特征、水文特征及断裂构造。根据以上特征可将区内沉积层自上至下划分为四个电性层,区内水体呈单一的潜水结构,潜水面受阻水断裂构造F1控制。该断裂使得祁连山山前侧向水流无法补给到312国道以东地区,在312国道附近自西向东潜水水位面由27 m左右迅速下降至150 m。
In order to find out the shallow lithologic stratification,water body occurrence and structural distribution at Fengle town of Wuwei city,a long section of high-density electrical method was laid at this area,the geoelectrical characteristics,hydrological characteristics and fault structures of the shallow loose sediments have been initially identified.According to the geoelectrical characteristics,the sedimentary layer at this area can be divided into four electrical layers are from top to bottom,the water body has a single diving structure,and diving surface is controlled by blocked water fracture structure F1.This fault makes the lateral flow in front of Qilian Mountain unable to supply to the east of 312 National Highway 312 and the diving water level drops rapidly from about 27 m to 150 m from west to east near 312 National Highway.
