岸堤水库大坝存在问题分析及对策——基于除险加固工程实践

Analysis of Previous Problems and Countermeasures for the Andi Reservoir Dam—Based on the Practice of Danger Removal and Reinforcement Project

摘要: 岸堤水库作为山东省第二大水库，是淮河流域沂河水系的重要水利枢纽，承担着防洪、灌溉、城市供水及发电等综合功能，其安全运行直接关系到下游150万人的生命财产安全及众多交通干线的正常通行。本文基于岸堤水库大坝除险加固工程施工图设计资料，系统分析了大坝在除险加固前存在的坝体质量、坝基地质、防渗排水、边坡稳定及附属设施等多方面问题，结合工程实际提出了针对性的除险加固对策，包括防渗墙增厚、帷幕灌浆、边坡防护、抗震液化处理等关键技术措施。通过实践验证，2021年完成除险加固后，大坝原有的安全隐患得到彻底解决，连续4年运行正常，2025年安全鉴定结果为一类坝，表明所采用的加固对策科学有效，为同类水利工程的除险加固提供了参考依据。

Abstract: As the second largest reservoir in Shandong Province, Andi Reservoir is an important water conservancy hub of the Yihe River system in the Huaihe River Basin, undertaking comprehensive functions such as flood control, irrigation, urban water supply and power generation. Its operation is directly related to the safety of life and property of 1.5 million people downstream and the normal operation of many transportation trunk lines. Based on the construction drawing design data of the danger removal and reinforcement project of Andi Reservoir Dam, this paper systematically analyzes the various problems previous in the dam before danger removal and reinforcement, including dam quality, dam foundation geology, seepage prevention and drainage, slope stability and auxiliary facilities. Combined with the project practice, targeted danger removal and reinforcement countermeasures are proposed, including key technical measures such as thickening of impervious wall, curtain grouting, slope protection, and seismic liquefaction treatment. Practice verification shows that after the completion of risk elimination and reinforcement in 2021, the original potential safety hazards of the dam have been completely solved, and it has operated normally for 4 consecutive years. The dam safety appraisal result in 2025 is Class I, indicating that the adopted reinforcement countermeasures are scientific and effective, providing a reference for the danger removal and reinforcement of similar water conservancy projects.
