摘要
在乌鸦嘴泉上游380m处,由于盖楼前挖地基、浇灌水泥以及建筑污水,使该泉电导率受到明显干扰。反过来,可以把这种干扰事件当作一种水文地质实验,根据建筑施工时间与乌鸦嘴泉电导率受建筑干扰的时间对比分析,推算乌鸦嘴泉裂隙含水层渗透流速;从地形标高和出露含水层水头高度,粗略地推算乌鸦嘴泉裂隙含水层渗透系数。
The conductivity of Wayazui Spring is obviously disturbed by ground digging and cement pouring while a house is built at head waters of Wayazui Spring 380m away, which can also be regarded as a hydro- geology experiment. The seepage velocity of Wayazui Spring＇s crevassed aquifer is calculated according to contrast analysis between the time of building works and the disturbance of the Spring＇s conductivity. The seepage coefficient of Wayazui Spring＇s crevassed aquifer is roughly calculated according to the topography elevation and the waterhead altitude of the crevassed aquifer.
