高拱坝坝基排水问题

Problem of Drainage in Dam Foundation of High Arch Dam

从工程事故实例启示和学习卡氏理论研究后，对高拱坝坝基排水目的、布置原则、排水方式及其技术参数拟设等进行浅析。其中技术参数指标，目前难于数理定量，特搜集国内外部分工程数据进行初拟，最后得到初步认识并提出建议，以供讨论。

By analysis on example of project defeats and on the Casagrande Theory,a elementary introduction on purpose,arrangement,mode and parameters for drainage in dam foundation of high arch dam is presented.The drainage parameters are so difficult to be determined that data from some projects in China and abroad are analyzed.Preliminary knowledge is gained finally and suggestions are proposed.
