【摘要】：大坝安全关乎坝体下游城镇、人员的生命财产安全,安全监测不可忽视,安全监测资料分析就是在安全监测数据整理的基础上,通过一系列的研究方法有效的了解大坝的安全状态,进而寻找出大坝运行的薄弱环节,了解大坝运行的发展趋势,进一步采取有效的工程手段、管理办法保证大坝安全稳定运行,提高大坝运行的安全管理水平。而对于发电企业,在保证大坝安全运行的情况下,提高水库运行水位进而增加发电量从而增加经济效益也是发电企业考虑的重点,本文主要介绍了在提高李家峡水电站运行水位后,李家峡水电站渗流监测情况,主要通过长序列观测资料分析,从量值和规律性两个方面,提取温度、水位与观测量的关系对比试验时段观测资料所反映的规律,从而对渗流观测大坝安全形态进行评价。本文通过对原始监测资料和加密观测资料的分析,判断高水位运行情况下大坝的运行状态并得出结论。
[Abstract]:Dam safety is related to the safety of the downstream towns of the dam body. The safety of human life and property can not be ignored. The analysis of safety monitoring data is based on the collation of safety monitoring data. Through a series of research methods to effectively understand the safety status of the dam, and then find out the weak link of the dam operation, understand the development trend of the dam operation, and further take effective engineering means. The management method ensures the safe and stable operation of the dam and improves the safety management level of the dam operation. For power generation enterprises, under the condition of ensuring the safe operation of the dam, it is also the focus of the power generation enterprises to raise the operating water level of the reservoir and thus increase the power generation and thus increase the economic benefits. This paper mainly introduces the seepage monitoring situation of Lijiaxia Hydropower Station after raising the water level of Lijiaxia Hydropower Station. The temperature is extracted from two aspects of quantity and regularity through the analysis of long sequence observation data. The relationship between the water level and the observed data is compared with the observed data in the experimental period, and the safety morphology of the seepage observation dam is evaluated. Based on the analysis of the original monitoring data and the intensive observation data, this paper judges the operation state of the dam under the condition of high water level operation and draws a conclusion.
