摘要
鉴于沥青混凝土心墙一直埋藏于坝体内部,因此,受气候变化影响较小,并且心墙变形适应性较强,防渗性能优越、结构简单、施工方便、抗震能力强、柔韧性好且安全可靠等诸多优点,选用该材料作为水电站的挡水建筑物防渗体。介绍了一套碾压式沥青心墙坝的设计过程,提出了碾压式沥青心墙结构,提出了处理坝基及坝肩基础的要求和标准,复核了该工程的坝壳料及坝体在各个工况下的渗透稳定性,抗滑稳定性及坝体的应力应变特性,结果表明:坝体结构合适,防渗系统、抗滑稳定、沉降变形均能满足设计要求,为此类坝型建设提供借鉴。
In view of the fact that the asphalt concrete core wall has been buried in the dam body all the time,therefore,it is less affected by climate change,and the core wall has many advantages,such as strong deformation adaptability,superior anti-seepage performance,simple structure,convenient construction,strong anti-seismic ability,good flexibility,safety and reliability,etc.,so this material is selected as the anti-seepage body of the water retaining structure of the hydropower station.This paper introduces the design process of a set of roller compacted asphalt core dam,puts forward the roller compacted asphalt core structure,puts forward the requirements and standards for the treatment of dam foundation and dam abutment foundation,reviews the dam shell material and the seepage stability,anti sliding stability and stress-strain characteristics of the dam body under various working conditions of the project,and the results show that the dam body structure is suitable,the anti-seepage system and anti sliding stability are suitable The settlement and deformation can meet the design requirements,so as to provide reference for the construction of this kind of dam in the future.
