摘要
选取山巴—川主寺段为拟选水源地,对研究区内地下水资源量进行了评价,对不同入渗条件及水头高度下的河水入渗补给能力进行了回归分析,建立了关系式。在此基础上,根据现场条件,以管井、大口径井、辐射井、渗滤井、渗渠或其组合形式进行取水工程方案比选,推荐了最优取水方案,为保障松潘县城及川主寺镇集中供水提供了技术支撑。
On the basis of previous research,the way of Shanba to Chuanzhusi town section is selected as the water source to be selected by means of hydrogeological survey,hydrogeological test and so on. The hydrogeological parameters are determined,the amount of underground water resources in the study area is evaluated,the infiltration recharge capacity of river water under different infiltration conditions and head height is analyzed by regression analysis,and the relationship is established. On this basis,according to the field conditions,the water intake engineering schemes are compared and selected in the form of pipe well,large diameter well,radiation well,infiltration well,seepage canal or their combination,and the optimal water intake scheme is recommended. It provides technical support for ensuring the centralized water supply in Songpan County and Chuanzhu temple Town,which has important theoretical and practical significance.
