MEASURING METHOD OF BENTONITE MIXED SOIL AND MEASURING DEVICE OF BENTONITE MIXED SOIL
PROBLEM TO BE SOLVED: To provide a measuring method and a measuring device capable of accurately calculating physical properties of a bentonite mixed soil by means of RI measurement to thereby solve a problem in conventional techniques.SOLUTION: Disclosed measuring method of a bentonite mixed soil is a method to measure physical properties of a bentonite mixed soil at a present position. The method includes: a test piece creation step; a preliminary RI measurement step; a preliminary destructive measurement step; a density correction equation setting step; a moisture content correction equation step; and an actual measurement step. In the density correction equation setting step, a density correction formula is set based on a second wet density in plural first wet densities. In the moisture content correction equation step, a water content correction formula is set based on a second water content in plural first water contents.SELECTED DRAWING: Figure 1
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、ＲＩ測定によってベントナイト混合土の物性を精度よく求めることができる測定方法と測定装置を提供することである。【解決手段】本願発明のベントナイト混合土の測定方法は、現位置のベントナイト混合土の物性を測定する方法であり、試験体作成工程と、事前ＲＩ測定工程、事前破壊型測定工程、密度補正式設定工程、含水量補正式設定工程、実測定工程を備えた方法である。このうち密度補正式設定工程では、複数の第１湿潤密度の第２湿潤密度に基づいて「密度補正式」を設定し、含水量補正式設定工程では、複数の第１含水量の第２含水量に基づいて「含水量補正式」を設定する。【選択図】図１
