If the ground where a manhole is constructed is susceptible to liquefaction during earthquake, the manhole may float up straight or cant. A series of model shaking tests were conducted 1) to investigate the failure phenomena due to liquefaction, and 2) to test the effectiveness of four types of manhole stabilization techniques against liquefaction, such as surrounding with crushed grain and sheet pile or dewatering to the bottom level of the manhole, compared with a manhole employing no stabilization technique. Based on measured accelerations, excessive pore pressures, and observed floating up and settlement, this paper describes the effectiveness of stabilizing techniques.
