沥青混凝土心墙堆石坝阵列式位移计安装探讨

Discussion on Installation of Array Displacement Meter for Asphalt Concrete Core Rockfill Dam

因常规监测手段的局限性,只能监测沥青混凝土心墙与周边细过渡料在竖直向的变形,而其水平向位移却无法观测,沥青混凝土心墙变形采用阵列式位移计监测,在国内应用并不多,沥青混凝土心墙变形监测安装的阵列式位移计须保证回填料与周边细过渡料强度相接近使其与心墙接触良好,确保其能正常、准确地反映心墙变形。

Due to the limitations of conventional monitoring means,only the vertical displacement between the asphalt concrete core wall and surrounding fine transition material can be monitored,and observation of its horizontal displacement is not available.Deformation monitoring of the asphalt concrete core through array displacement meter is not widely used in China.Array displacement meter is required to be installed in a manner that the backfilling material is of the same strength as the surrounding fine transition material and is in close contact with the core wall,so as to ensure that core wall deformation can be normally and accurately reflected.
