摘　　要：结合对以宝坻新台井为中心、半径约3 km地域范围内的地下水开采井的调查结果、宝坻新台井概况和所在地区的水文地质资料以及对重点影响井——杨家口村生活井的抽水实验,就宝坻新台井水位对周边地下水开采的响应特征进行了研究,结果表明:宝坻新台井对周边地下水开采的响应是邻层抽水效应的结果,井管漏点、含水层组间"通透"很可能也是重要的影响因素;杨家口村生活井开采地下水时宝坻新台井水位分钟值曲线会出现下降型畸变,开采结束后逐渐恢复,响应的滞后时间在1 min之内;杨家口村生活井持续开采地下水7 h实验过程中,宝坻新台井水位分钟值曲线下降型畸变持续存在,未呈现出"平衡状态";宝坻新台井水位对周边地下水开采的响应可能是由于井管存在漏点或井管外存在空隙的原因所致。Binding on survey results of exploitation data of the wells about 3 km radius around Baodi new seismic station well, Baodi new station well profile and hydro geological data, and Yangjiakou village life well sustained pumping experiment, the paper preliminarily studies the response characteristics of water level inBaodi new seismic station well by the surrounding groundwater exploitation. The results show that： the response of water level of the Baodi new seismic station well to the surrounding wells groundwater exploitation is mainly influenced by mining of Yangjiakou village life well with about 2 km away from the new station; during the water mining in Yangjiakou village life well, minute value curve of water level in Baodi new seismic station well will decrease in distortion, and it will gradually recover after the end of mining with lag time less than 1 min; the descending distortion still existed in the minute value curve of water level of Baodi new seismic station during the sustainable exploitation experimental process of groundwater in Yangjiakou village well for 7 hours, which did not appear ＂balance＂; the response of water level of Baodi new seismic station well to water exploitation may be due to the leak in Baodi new seismic station well pipe or the void outside the well pipe.
