Abstract
This paper presents a case history of trench collapse occurred during trench excavation in soft ground. The development of settlement and horizontal displacement, the generation of pore water pressure during the construction and mechanism of trench collapse are investigated by means of centrifuge modeling and numerical analysis. It is found that the combination of centrifuge modeling and in-flight sand hopper can provide dramatic result for simulation of the trench collapse. Based on the results, it is verified that the occurrence of trench collapse is mainly caused by the excessive surcharge load of excavated material stockpiled on top of the trench.
