| Abstract | A comprehensive set of laboratory investigations was carried out to study the general behavior of granular - fine mixtures under repeated wetting and various stress conditions. The crushed rockfill used in the construction of the Chiew Larn Dam, Southern Thailand, was studied in this research by means of Rowe cell apparatus (15. 24 cm in diameter). A review of known investigations of engineering behavior on granular materials is presented herein, along with the some experimental index properties results of author's studies on this subject. The experimental work described herein includes mainly One Dimensional Compression tests. The samples were prepared at a dry density of 2. 0 t/m3 with variation of fine content 0, 5, 10, 12, 13. 5, 15% and 20%. The gradations A, B, C, D, E were tested in initially dry, initially wet and initially dry, then wet conditions. The gradation F, G were tested under dry condition. Through all these One - Dimensional Compression tests, the effect of gradation, fine content and wetting and draining cycles were investigated and discussed. The experimental investigations by means of the One Dimensional compression tests show that the compressibility is at a maximum when the fine content contained in the samples was 12% and from then on, the compressibility is decreased. The One - Dimensional compressibility of the granular material is significantly influenced by wetting . The axial strain of the initially dry, then wet sample is 1. 3 to 1. 8 times greater than that of the dry sample at different stress levels and different fine content. The strain increment due to wetting cycles is increased with the increase of fine content and stress levels. The difference in strain between initially wet and initially dry, then wet condition is also increased with the increase of fine content. For pure granular materials, the initially dry, then wet condition stress strain curve follows that of the initially wet condition. |
