This paper aims to introduce research progress on liquefaction resistance and internal erosion features of non-plastic silty sand. Contents of this paper include the field application of a new sampling technique that would allow sensitive and high-fines content silty sand material to be retrieved in sounding condition; laboratory test results on liquefaction resistance of non-plastic silty sand emphasized on the influence of fines content; and finally, results of utilizing a specially designed test device, Flexible Wall Pin Hole Test Device, to investigate the internal erosion characteristics of non-plastic silty sand. It concludes that higher non-plastic fines content of silty sand would result in lower cyclic liquefaction resistance as well as higher internal erodibility. Moreover, the indicated trends would become more obvious when such non-plastic silty sand was subjected to disturbance. Results of this study will to improve engineers' understanding on engineering behavior of non-plastic silty sand.
