摘要/Abstract

摘要： 黄河公司于2009~2010年开展了李家峡大坝原型观测试验，利用上游拉西瓦水电站2009年3月下闸蓄水和其后抬升水位的有利时机，人为调控水库水位进行原型观测试验，获取了大量有效的试验监测数据并结合大坝运行期监测资料和之前相关的研究成果进行了深入研究，建立了李家峡大坝安全快速评估体系，能够及时准确地分析评价大坝在高水位运行和水位短期内小幅波动下大坝的运行状态及规律，研究成果达到了预期目标。笔者简要介绍李家峡大坝原型观测试验研究及其成果，供借鉴。

Abstract: The prototype observation of Lijiaxia dam was carried out during 2009~2011. Grasping the favorable opportunity of impoundment and the subsequent uplifting of water level of Laxiwa reservoir, prototype observation was carried out with manual control of reservoir level and a great deal of valid data were obtained. Combined with the monitoring data in operation, in-depth analysis was conducted and assessment system for dam safety was built which would analyze with high accuracy on the operation performance and laws during high reservoir level and with a slight fluctuation of water level. The study results were satisfactory. The paper introduced the experimental study on the prototype observation of Lijiaxia dam and the results, for reference.

Key words: Lijiaxia dam, working performance, prototype observation
