Abstract
About 15 to 20 workers die annually in labor accidents attributed to slope failure or rock fall during slope excavations in Japan. In this paper, a case history of slope failure occurred during the reconstruction of retaining wall is presented. The geotechnical centrifuge model tests are conducted to investigate the mechanism of slope failure. This paper focuses on the influence of wall stiffness and embedded depths of sheet piles or pipes on the prevention of slope failure. Based on the centrifuge test, it was found that the simple temporary wall used during the trench excavation in this case history could not protect to worker from the slope failure.

Case History of Labor Accident Due to Slope Failure During Slope Excavation and Its Countermeasure Work
