浇筑式沥青混凝土心墙防渗结构最大特点是适合寒冷地区冬季施工.其耐久性、防渗可靠性、裂缝自愈能力、抗冲击性能均优于混凝土面板防渗结构.在恶劣气候条件下易保证浇筑层面接合质量.浇筑速度快,便于施工管理和质量控制.其施工导流费仅占主体工程投资的4%～6%.施工过程中可蓄水,后期维护费用低.本文就西沟、碧流河、白河等工程施工,试验研究了该防渗结构的裂缝自愈功能、心墙变形应力状态.就结构布置、厚度选择、心墙与坝基的连接方式、分析模型及计算参数提出了设计技术要求.目前这种坝型工程类比经验较少,设计原理有待进一步发展、完善.
Pouring asphalt concrete core wall anti-seepage structure is the most prominent feature for winter construction in cold areas. Its durability, seepage reliability, crack self-healing ability, impact resistance are better than the concrete panel seepage control structure. In harsh weather conditions easy To ensure the quality of pouring level bonding.Pouring speed, ease of construction management and quality control.Its construction diversion fee accounted for only 4% to 6% of the main project investment.Construction of the process can be water, low maintenance costs later.This paper on the West ditch , Biliuhe River and Baihe River, etc. The self-healing function of cracks and the deformation state of the heart wall are studied experimentally.The structural layout, thickness selection, connection mode between core wall and dam foundation, analysis model and calculation parameters are proposed The design and technical requirements.At present, this type of dam engineering analogy less experience, design principles to be further developed and improved.
