Abstract :
The excavation of foundation pits is usually confronted with many potential risks during the long construction time. Risks often come from varies of working procedures. Many factors may cause the procedures failing, but human errors show the greatest probability to cause accidents. Luke Model is a valid method of quantitative analysis for human factors. Through quantitative analysis, get the failure probability of excavation engineering caused by human factors. Based on these probabilities, use method of entropy weight measurement to calculate risks degree and coefficient of entropy weight of each human factor. Finally control the risks of each working procedure according to these two indexes and eventually get the aim of reducing risks maximally.
