鲁布革坝的原型观测（一）

本文全面叙述了鲁布革坝自１９８７年１月开始填筑，至１９９１年６月的变形、渗流、土压力原型观测结果的整理分析，及对其安全评价。经初次正常高水位的运行，大坝是安全的。但也存在一些应予重视的不安全因素，如两岸剪切位移、拉伸位移均较大，可能使心墙与两岸混凝土垫层接触不紧密，接触面的抗渗条件也比心墙内部差，以及在坝顶接触面部位产生裂缝等。

Prototype observation of Lubuge Dam

The results of prototype observation of Lubuge Dam in the deformation,seepage and soil pressure from Jan. in 1987 to Jun. in 1991 are presented comprehensively in this paper.The dam is safe after first normal high water level. But some unsafe factors should be noticed,for example,the shear and tensile deformation near the two side bank are greater,the connection of the core and concrete course in the side bank is loose, the seepage condition of contact face is worse and the crack is produced at the top of dam.
