【摘要】：為監(jiān)測黃河龍羊峽水電站壩體與壩址區(qū)垂直位移，庫區(qū)以及壩址下游區(qū)的庫盤垂直形變，按設(shè)計要求分別布置了長度約15km、9km、25km一等精密水準(zhǔn)路線，構(gòu)成垂直位移監(jiān)測系統(tǒng)。 從觀測設(shè)計角度評價，該網(wǎng)存在以下需解決的問題：野外觀測工作量大；技術(shù)要求高；端點處精度差；觀測頻率低。與精密水準(zhǔn)相比，應(yīng)用GPS技術(shù)進行庫盤垂直形變監(jiān)測，精度完全能達(dá)到精密水準(zhǔn)要求且能滿足國標(biāo)相關(guān)規(guī)范要求，同時具備省時、省力、省錢等優(yōu)點。 為此，在2007年龍羊峽水電站大壩安全定檢專家會議報告中要求：研究使用GPS高程替代精密水準(zhǔn)進行庫盤垂直位移觀測的可行性及針對龍羊峽庫區(qū)的網(wǎng)形設(shè)計。以克服目前使用的精密水準(zhǔn)觀測系統(tǒng)缺陷，為大壩安全分析提供可靠的數(shù)據(jù)。 本文采用理論與實踐相結(jié)合的研究方法。通過現(xiàn)場調(diào)查、優(yōu)化設(shè)計、觀測驗證最終對龍羊峽水電站壩址區(qū)垂直位移及壩址下游區(qū)的庫盤垂直形變實施GPS監(jiān)測形成統(tǒng)一的設(shè)計方案，完成龍羊峽水電站精密水準(zhǔn)觀測優(yōu)化設(shè)計和實測驗證。
[Abstract]:In order to monitor the vertical displacement between the dam body and the dam site of Longyangxia Hydropower Station on the Yellow River, the vertical deformation of the reservoir plate in the reservoir area and the downstream area of the dam site has been monitored. According to the design requirements, the first precision leveling route of about 15km ~ 9km2 ~ 25km has been arranged, which constitutes a vertical displacement monitoring system. From the point of view of observation design, the network has the following problems to be solved: the workload of field observation is large, the technical requirement is high, the precision at the end point is poor, and the observation frequency is low. Compared with precision leveling, using GPS technology to monitor vertical deformation of storehouse disk can completely meet precision leveling requirements and meet the requirements of relevant national standards, and it also has the advantages of saving time, labor, saving money, and so on. Therefore, in the report of the expert meeting on dam safety determination and inspection of Longyangxia Hydropower Station in 2007, it is required to study the feasibility of using GPS elevation instead of precision leveling to observe vertical displacement of reservoir plate and to design the grid for Longyangxia reservoir area. In order to overcome the defects of precision leveling observation system used at present, reliable data are provided for dam safety analysis. This paper adopts the research method of combining theory with practice. Through field investigation, optimization design, observation and verification, a unified design scheme was formed by GPS monitoring of vertical displacement in dam site and vertical deformation of reservoir plate in downstream area of Longyangxia Hydropower Station. The optimization design of precision leveling observation and the verification of actual measurement for Longyangxia Hydropower Station are completed.
