摘要
鉴于补强修复和除险加固作为水工结构领域中一项重要工作和长期任务,对保障工程服役安全、发挥工程效益、延长工程服役周期等具有极其重要的意义,在保证结构安全可靠的前提下,考虑结构性能的劣化特性,从优化工程全寿命周期成本的目标出发,引入全寿命周期成本理论,研究水工结构维修加固成本计算与决策模型及其算法,并应用于某水工结构工程中,优化制定其全寿命周期内具体维修方案。研究结果表明,文中所述模型可为制定水工结构工程在全寿命周期内的维修加固策略提供一定的科学依据。
Reinforcement recovery and reinforcement is an important work and long-term task in the field of hydraulic structure,which are of significance to ensure the safety service of the project,to develop the project benefit,and to extend the service period of the project.The cost calculation and decision making model of hydraulic structure maintenance and reinforcement and its algorithm are established under the premise of ensuring structure safety and reliability,with the consideration of the deterioration characteristics of structural performance and the introduction of life cycle cost theory from the objective of optimizing the whole life cycle cost in engineering.The proposed method is applied to a hydraulic structure,and the concrete maintenance plans during the whole life cycle are calculated and formulated.The result shows that the models and methods in this paper can provide some scientific basis for the maintenance and reinforcement strategies of hydraulic structures in the whole life cycle.
