MOISTURE CONTENT RATIO MEASUREMENT DEVICE, SETTING PROGRAM OF ESTIMATION EQUATION OF MOISTURE CONTENT RATIO, AND MOISTURE CONTENT RATIO MEASUREMENT METHOD
To provide a technique which can estimate a moisture content ratio of a ground with higher accuracy by using spectrum data obtained by a spectrometer.SOLUTION: A moisture content ratio measurement device 100 measuring a moisture content ratio of a ground while moving comprises: a moving body 101 moving on the ground; a spectrometer 102 attached to the moving body 101; and moisture content estimation means 103. The moisture content ratio estimation means 103 is means for estimating the moisture content ratio of the ground based on a reflection intensity for each wavelength of the ground and a preset moisture content ratio estimation equation. The moisture content ratio estimation equation is acquired by performing a multiple regression analysis using a reflection intensity for each wavelength and a moisture content ratio of a plurality of kinds of sample soils with a different moisture content ratio.SELECTED DRAWING: Figure 1
【課題】分光計によって得られるスペクトルデータを用い、より高精度で地盤の含水比を推定することができる技術を提供する。【解決手段】含水比測定装置１００は、移動しながら地盤の含水比を測定する装置であり、地盤上を移動する移動体１０１と、移動体１０１に取り付けられる分光計１０２、含水比推定手段１０３を備えたものである。このうち含水比推定手段１０３は、地盤の波長別反射強度と、あらかじめ設定された含水比推定式と、に基づいて地盤の含水比を推定する手段である。なお含水比推定式は、含水比が異なる複数種類の試料土の波長別反射強度と含水比を用いた重回帰分析を行うことによって求められる。【選択図】図１
