【Abstract】 Event tree method is sufficiently flexible to deal with a variety of random factores in nature and knowledge of uncertainties.By the way of event tree theory and method,analyzed and evaluated construction risk of the current China first large-diameter ultra-deep-hole into the rock-socketed pile.Based on those,it has achieved good control effect.更多还原
