摘要
句容抽水蓄能电站上水库大坝高180.23 m,坝顶长810 m,围岩结构复杂,存在硅质白云岩条带、闪长岩、断层等不利地质情况。上水库堆石坝内部变形引进分布式光纤监测埋设布置,结合常用的引张线式水平位移计和水管式沉降仪监测成果对比分析,数据拟合性较好,光纤长期耐久性好、抗干扰能力强、可分布式测量的优点,有效保证仪器的完好率,最为关键的是可以获取堆石体内部的连续变形情况,对反馈工程施工质量、加快工期起到积极作用,保障工程安全,值得推广应用。
The dam of the upper reservoir of Jurong Pumped Storage Power Station is 180.23 m high,with a crest length of 810 m.The surrounding rock structure is complex,and there are unfavorable geological conditions such as siliceous dolomite bands,diorite,and faults.The internal deformation of the Shangshui Reservoir Rockfill Dam is monitored by the introduction of distributed fiber optic monitoring and burial arrangements.By comparing and analyzing the monitoring results of commonly used tension line type horizontal displacement meters and water pipe type settlement meters,it is found that the data fitting is good.The advantages of fiber optic long-term durability,strong anti-interference ability,and distributed measurement effectively ensure the integrity of the instruments.Most importantly,it can obtain the continuous deformation inside the rock mass,which plays a positive role in feedback engineering construction quality,accelerating construction period,ensuring engineering safety,and is worth promoting and applying.
