第五次全国渠库防渗科技经验交流会于1990年9月上旬在贵阳市花溪召开。 会议认为,目前我国的渠库防渗科技已步入了一个新阶段:渠道防渗工程技术即将规范化;渠库防渗总体规划和综合效益的研究将更加普及;大流量、跨流域引水工程的防渗科研将进入协同攻关的阶段;中小型渠库防渗由于讲求经济效益将更多更快地引用最新科技成
The Fifth National Drainage Seepage Technology Experience Sharing Conference was held in Huaxi, Guiyang in early September 1990. The meeting held that, at present, China’s trench seepage control technology has entered a new stage: channel seepage control technology will be standardized; seepage control overall planning and comprehensive benefits of the study will be more popular; large flow, interbasin water diversion project Anti-seepage research will enter the stage of collaborative research; small and medium-sized reservoir seepage seepage economic benefits will be more and more quickly cited the latest technology into
