编者按为保证大坝运行安全和提高水利建设的科学技术水平,长办对大坝安全监测工作极为重视,自1958年汉江丹江口水利枢纽兴建时开始,即组织专门力量承担这项工作。安全监测的关键在于通过埋设仪器实测大坝的性状与设计中预期的大坝性状进行对比,从而判明大坝的实际安全状态。因此,如何从设计采用预计大坝性状的数学模型出发,建立起预报大坝运行性状的决定论类型的模型,是一项重要的工作。这项工作,长办勘测总队与长江水利水电科学院协同一致,组成工作小组,结合长江葛洲坝水利枢纽安全监测资料的整理分析工作,1982年起分阶段、有步骤地展开,于今已取得初步成果。本文是提交今年6月在瑞士举行的第十五届国际大坝会议的论文。本刊现予发表,一则供同志们评论,二则希望工作小组更认真地吸取众长,更深入地掌握实际情况,继续努力探索,早日完成安全监测自动化的全部计划,为三峡工程的安全监测作出有益的贡献。
Editor In order to ensure the safety of the dam operation and improve the scientific and technological level of water conservancy construction, CFO attaches great importance to dam safety monitoring work. Since the construction of Danjiangkou hydro-junction in Hanjiang River in 1958, it has organized special forces to undertake this work. The key to safety monitoring lies in comparing the actual measured dam characteristics by embedding instruments with the expected dam behavior in the design to determine the actual safety status of the dam. Therefore, how to set up a model of deterministic type for predicting dam operating characteristics from the perspective of designing a mathematical model that predicts dam behavior is an important task. In this work, the Long Survey Reconnaissance Corps and the Yangtze River Water Conservancy and Hydropower Academy are coordinated to form a working group which, combined with the collation and analysis of safety monitoring data of the Gezhouba Dam, has been phased in since 1982 and has achieved preliminary results so far . This article is a submission for the fifteenth International Conference on Dams held in Switzerland in June this year. This issue appears to be published, one for comrades comment, two hope that the working group to learn more deeply, to grasp more the actual situation, continue to work hard to explore, early completion of safety monitoring automation of the entire plan for the safety of the Three Gorges Project Monitoring makes a useful contribution.
