一些已建成的小型水库,在设计和施工时均未进行地质勘探工作,对隐伏的可能形成漏水通道的岩层断裂带和破碎带以及次生构造裂隙,也未进行工程处理。因此,漏水的现象时有发生,有的严重削弱了灌溉效益。对于这类工程,进行既经济又科学的整治,是一个值得 Some of the completed small reservoirs did not carry out geological exploration during the design and construction, nor did they process any concealed strata and fractured rock formations and secondary structural fractures that might form water leakage channels. Therefore, the phenomenon of leakage occurred from time to time, and some seriously weakened the irrigation benefits. It is worthwhile for such projects to be economically and scientifically rectified
