| Abstract | Two types of sand compaction pile (SCP) model tests have been carried out to investigate the engineering properties of locally-available, low-quality sand materials in Thailand. The SCP model tests were performed using both drop hammer and hand-operated vibrator in one case and using vibrator only in another case. The sand samples used in the study were taken from three sources, namely Kampengsen, Ayutthaya, and Chonburi areas. These samples were compacted at ·three different relative densities: 60%, 70%, and 90%. Cone penetration test (CPT) and standard penetration test (SPT) were conducted in each set-up under overburden pressure of 10 tsm. The permeability and settlement of the samples were measured. Laboratory tests were also performed to examine the physical and engineering properties of the three sand samples and provide a comparison to the field model tests. The laboratory tests include grain size analysis, specific gravity, maximum and minimum dry density, constant head permeability test and direct shear test. Kampengsen sand has the highest values in coefficient of permeability and internal friction angle as compared to the other two materials. It has less fine content and large particle size. Ayutthaya sand is composed of fine grain particles and has 10% passing number 200 sieve. Chonburi sand has fine content of 19% passing number 200 sieve and exhibited a lesser internal friction angle. However, Chonburi sand has a higher permeability as ·compared to Ayutthaya sand. These locally-available and low-quality sands exhibit satisfactory engineering properties and behavior and therefore can be used as construction material for sand compaction piles (SCP). |
