Abstract:26 cases were collected to analyze the risk of the artesian water for the deep excavation, such as pit piping and bracing seepage and flowing sand. Then the fault tree analysis was employed to identify the factors of the risk of the artesian water. Furthermore, the sensitivity analysis was employed to array the factors of the risk of the artesian water. Finally, the precautions and the emergency measures of the risk of the artesian water for the deep excavation engineering were proposed, and the results provided a reference for the similar engineering.
