扎渃玛五一大坝碾压式沥青混凝土心墙施工技术

Construction technology of high earth-rock dam with asphalt concrete core wall

本文以沥青混凝土心墙高度最大的扎渃玛五一大坝为例,从沥青混凝土的配料、拌制、运输、摊铺碾压等方面阐述了大坝碾压式沥青混凝土心墙的施工技术和方法,结合试验成果及技术要求,提出了沥青混凝土心墙的施工质量控制措施,解决了沥青混凝土心墙施工过程中的重难点问题,可供国内外类似工程参考.

Taking the ZAREMA 51 dam with the highest to asphalt concrete core wall an example,This paper expounds the construction technology and method of asphalt concrete core wall in dam from the aspects of batching,mixing,transportation,spreading and rolling of asphalt concrete,combined with the related test result and technical requirements,puts forward the measures for the control of the quality of asphalt concrete core wall,The key and difficult problems in the construction of asphalt concrete core wall are solved,which can be used as reference for similar projects at home and abroad.
