摘　　要：格里桥水电站下闸蓄水后不久,实施了引水隧洞充水与放空试验,经历了充水-放空-再充水-再放空-再充水的过程,在此过程中渗压计的实测压力与充放水过程有明显相关性。因厂房后边坡变形较大,浇注灌注桩抗滑,通过灌注桩钢筋计实测应力的变化,判断抗滑效果及边坡稳定性,并对混凝土应力进行简单计算。Shortly after impoundment of Geliqiao hydropower station, the test of filling and emptying of the diversion tun- nel was carried out. In the filling-emptying-filling-emptying process, the pressure measured by piezometers had obvious relevance with the process. As large deformation of rear slope of powerhouse, concrete piles were poured for slide resis- tance. Strain gauges were arranged on the concrete piles to monitoring the stresses, further, to provide basis for evaluation of anti-sliding effect as well as judgment on slope stability. Moreover, the concrete stresses were calculated.
