拉洛水利枢纽及灌区工程碾压式沥青混凝土心墙施工技术研究

Technical studies on crushing asphalt concrete core wall for Laluo Multi-purpose Project and its irrigation systems

根据沥青混凝土心墙设计技术指标及参数要求,西藏拉洛水利枢纽沥青混凝土心墙坝通过现场试验等方法确定沥青混凝土施工配合比及沥青指标,并参考已建沥青混凝土心墙坝工程建设经验,对拉洛水利枢纽沥青混凝土心墙坝的混凝土拌和、运输、摊铺、碾压施工提出具体要求。通过取芯检测,认为采用该方法满足设计要求。

In accordance with technical indicators and parameters of asphalt concrete core wall design,the matching ratio and asphalt index of Laluo dam project were defined by on-site experiments.Specific requirements were proposed for concrete mixing,transportation,paving and compaction construction through reference of construction experiences of existed dam projects.According to core detection,it is demonstrated that the methodology can satisfy the design requirements.
