ROLLING COMPACTION CONTROL METHOD AND DEVICE FOR FILLED FACE

摘要

PROBLEM TO BE SOLVED: To provide a rolling compaction control method and device for a filled face capable of considerably reducing labor, time and cost while evaluating the quality of a filling material with high accuracy abreast with rolling compaction control work of the filled face. SOLUTION: Information showing the relation between vibration acceleration generated to a vibrating roller when rolling a test material by the vibrating roller, and the internal friction angleϕ, water content w and density of the test material corresponding to the vibration acceleration is acquired beforehand (S1-S3). The vibration acceleration of the vibrating roller generated when actually rolling the filled face by the vibrating roller is measured (S4). The internal friction angle and density are immediately computed from the vibration acceleration measured when rolling the filled face, and the previously acquired information to determine whether the filled face is the ground of prescribed quality (S5).
