Study on Characteristics of Soil Compaction using Accelerometer

진동가속도계를 이용한 지반다짐 특성 연구

Soil compaction works are essential to construction of dams, breakwaters and roads in order to avoid unexpected settlement/deformation of superstructures. Taking advantage of oscillating accelerometer, this research was made to complement existing methods for assessment of soil stiffness. In order to examine the validity of compaction-degree suggested in the study, tests on vibration characteristics using accelerometers was also performed. Test results for sand and gravel mixtures and Korean standard sands were compared and evaluated by conventional assessment methods under varying conditions as of input frequency, size of loading plate and relative density.
