摘　　要：沥青混凝土心墙设计控制指标的目的是指导现场配合比试验、碾压试验、碾压填筑施工以及对填筑施工质量进行评价分析。由于沥青混凝土材料力学性能指标受试验环境、试验方法等影响较大,可能出现难以满足设计控制值的情况,从而导致设计控制指标与质量评价分析之间的矛盾。为此,结合黄金坪水电站沥青混凝土心墙施工过程中,设计控制指标与规范的差异情况及其对大坝稳定、应力变形的影响等,对规范的相关规定以及实际应用进行探讨。The purpose of design control indexes of asphalt concrete core wall is to guide on-site mix ratio test, rolling test,rolling construction and construction quality evaluation. Because the mechanical properties of asphalt concrete materials are seriously influenced by test environment and method, the indexes may be difficult to meet the design control values, which will cause the contradictory between design control indexes and quality assessment. Taking the asphalt concrete core wall construction in Huangjinping Hydropower Station as an example, the differences between design control indexes and specifications＇ values are analyzed and its influences on dam stability and deformation are also analyzed. Based on above analyses, the relevant provisions of specifications and its practical application are also discussed.
