| Summary: | Dynamic Compaction (DC) is a recognized and an accepted technique for stabilization
of loose or granular soil conditions. This method has been used to improve bearing
capacity. The technique involves dropping weights from cranes at specified heights.
The purpose of dropping the weight is to transmit compaction energy to the soil mass
for densification. This method works best in loose sands, fills, rubble, and landfills
(Vipulanandan, 1998). This study was done to find out the fine content of soil improved
by dynamic compaction. The sampled soil obtained adjacent to Kemaman-Kertih
Railway track by using wet borehole technique. The borehole was driven at 12 different
locations. For each borehole, the sample was collected at every 0.5 m interval until
sufficient 1Kg was sampled and depth reached 7.5 m. Based on BS 1377, laboratory
testing procedures such as for moisture content, wet sieve and dry sieve were conducted
to determine the moisture content as well as soil classification. Laboratory testing took
place at UiTM Pulau Pinang Laboratory. The percentages of fine content for every
chainage were calculated and the soil profiles at study area were drawn by AUTOCAD.
Based on result, the relationship between soil profile and suitability of ground
improvement technique was discussed. |
