| Summary: | 碩士 === 國立交通大學 === 土木工程系所 === 92 === During the past 40 years, extensive laboratory studies on undrained stress-strain behavior and liquefaction resistance of clean sands have been performed. Natural sands often contain various amounts of fines and are expected to have different behavior. This research concentrated on Mai Liao Sand(MLS), which is a typical silty sand found in Central Western Taiwan. MLS is relatively compressible and has less tendency to dilate when sheared.
A series of cyclic triaxial tests have been performed on MLS with different fines content in this research. A triaxial cell equipped with bender elements was used to measure cyclic strength and shear wave velocities of the specimen. The thesis describes the background of the research, objectives, and it’s approach. The test results were analyzed and the influence of fines contents on MLS were discussed.
