摘要
张掖市区近年来地下水位的变化幅度较大,由于长期的周期性的地下水位变化引起了建筑物的各种工程问题。针对张掖市地下水资源丰富且近年来地下水位持续上升的现状,开展地下水位变化监测及统计分析。结果表明,黑河河床过水时间增加和祁连山冰雪的消融使地下水补给量增大,导致地下水位上升,在2015年6月至2016年6月期间,张掖市区地下水位最高水位点为1 423.988 2 m,最低水位点为1 418.124 3 m,3个代表性点地下水位的年内变幅最高为2.039 8 m,最低为0.880 6 m。
In recent years,the change amplitude of groundwater level in Zhangye City is larger. Various engineering problems on buildings emerged due to the long period of groundwater level variation. Therefore,it is of great scientific value to carry on the research on the change of groundwater level and its influence on building mechanism in Zhangye city on the basis of the rich groundwater resources and the current situation of its increasing level. It is proved that the rise of the groundwater level is caused by the large quantity of water in Heihe river and the melting of snow and ice along Qilian mountain. The highest groundwater level point from June 2015 to June 2016 is 1423. 9882 m and the lowest point is 1418. 1243 m. The amplitude of underground water level in the three representative points of the year ranges from 0. 8806 m to 2. 0398 m.
