摘要
静力水准仪具有测量精度高、测量范围大、测值稳定可靠、不受外界干扰等特点,适应大坝监测环境。在碧口大坝监测系统中,静力水准能很好地监测双向引张线液面高度,对引张线垂直方向的位移进行修正和补充,引张线管道液面静止状态与改造前溢流状态相比,管道内水体的比降相等,使得引张线垂直位移更精确、更可靠。
Static water level has the characteristics of high survey accuracy, large survey scope, stable and reliable measured value, free of outside interference and adapted to the dam monitoring environment. In the Bikou dam monitoring system, the static water level can monitor the liquid surface height of bi - directional tension wire, modify and supplement the displacement of the tension wire in the vertical direction. Comparing the liquid surface static state of the tension wire pipe to the overflow state before upgrading, the gradient of pipe water is equal, which makes the vertical displacement of tension wire more accurate and reliable.
