摘　　要：从双金属标的组成、原理、观测等方面,阐述双金属标在乐昌峡水利枢纽中用以量测坝体内部垂直绝对位移的应用。Bimetallic standard is applying the differences in thermal expansion coefficients of aluminum and steel tube characteris -tics, absolute displacement measured perpendicular to the dam , or as hydrostatic level measurement , level base.Deformation moni-toring on its hinges , and decorated with bi-metal standard facilities as system base of vertical displacement can be overcome due to various reasons-error in the system.From the bi-metal standard observational aspects of composition , theory, application of bimetal mark in feilaixia lechang .
