Application of Risk-time Function to the -35.3m Scale Pit Deep Excavation of Baosteel Project

摘要：

In this paper the risk-time function is presented for qualitative and quantitative risk analysis based on the character of deep excavation in soft soil layers. Qualitative risk analysis shows that deep well dewatering failure and bottom boiling are the most important risk factors of scale pit deep excavation. Quantitative risk-time function analysis can estimate the risk at the time of peak value of excavation failure probability, and show that dewatering the second aquifer can reduce the total risk of bottom boiling failure greatly at low cost.
