Study on electrical monitoring of fill-up improvement. Utilization of resistivity data for soil compaction management; Hiteiko mitsudo kanri ni kansuru kisoteki kenkyu. Moritsuchi seko kanri eno hiteiko yuko riyo

Abstract

At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.
