摘要
本文基于已进行的西北口混凝土面板堆石坝的原型观测埋设工作,针对此种坝型的特点,总结。归纳并讨论了其原型观测布置的若干原则与例证。在埋设技术上,对于堆石坝强调了应提倡非坑槽式与不突出坝面的埋设技术,强调了仪器基床与仪器保护的重要性。对于混凝土面板,针对其截面窄小与坡度陡峻的情况,分别讨论了其表面与内部仪器的埋设技术,同时指出了现行埋设非应力应变计方法的缺点与问题。
Based on the prototype observation of Xibeikou concrete face rockfill dam, the paper summarizes and discusses some of the observation arrangement principles and presents several typical examples. For the embedding technique of observation instruments, the paper suggests 'non-pit' embedding method, and in addition, emphasizes the importance of the embedding base bed used for installing observation instruments. Finally, the paper discuses the embedding method of the instruments used for the observation of the surface and inner part of the concrete face slab respectively.
