MANAGEMENT METHOD ON EMBANKMENT FILLING HEIGHT PER DAY ON SOFT GROUND

摘要

PROBLEM TO BE SOLVED: To provide a management method to determine any area without failures where an embankment filling height per day is lower than or equal to a management reference value as well as to economize measurement performance and measurement work for an embankment filling on a soft ground using a slow filling construction method.;SOLUTION: A management method comprises a first process including measuring position coordinates of a tamping machine during operation using GNSS, performing a management on a tamping on embankment filling using a tamping management system to control tamping numbers on the embankment based on a measured data of the position coordinates, and acquiring a log file with a construction date, and a working time and position coordinates (x, y, z) of a tamping machine from a measured record, a second process including arbitrarily dividing an embankment area to a plurality of blocks in a plane and calculating a mean value of embankment filling height per day on each of mean values on the plurality of blocks based on data of the log file, a third process including determining on each of the plurality of the blocks whether the embankment filling height per day is lower than or equal to a management reference value, and a fourth process including visually displaying on each of the plurality of the blocks whether the embankment filling height per day is lower than or equal to the management reference value.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2018,JPO&INPIT
