This research is to study the effect of sheet pile length on the capacity of sheet pile foundation.

The sheet pile foundation is a shallow footing that is skirted by sheet pile around the periphery. From the previous study, it was indicated that sheet pile can dramatically improve the vertical, horizontal and moment capacities of the existing shallow foundation. This study was performed in the laboratory by using 1g physical modeling test. The new equipment was newly designed and developed in order to study the sheet pile foundation's behavior resting on sand under vertical loading test. The local sand in the Northeastern area was selected in this study. The ground models in the same conditions were prepared in the container tank by the pluviation. The effect of sheet pile length to the capacity of existing shallow footing can be evaluated by the results of load-settlement relationship. The reference case performed with shallow footing was also tested for comparison purpose.

The results show the effectiveness of sheet pile to increase the capacity of shallow foundation. An appropriate sheet pile length was also found from this study. Pictures taken during the loading steps in cooperation with image processing technique can be used to identify the mode of failure and can be used to calculate the soil movement and displacement vector below the foundation.Ttdhhdhd
