Abstract: Ground settlement induced by foundation pit excavation is one of important problems in foundation pit engineering in soft soil area.The factors influencing the ground settlement are complex and have stochastic and fuzzy properties,which have brought difficulties to the ground settlement analysis.Based on intelligent method of BP artificial neural network,the intelligent ground settlement analysis system is established.For this purpose,powerful functions(Including mapping ability,self-learning ability and generalization ability) of artificial neural network for nonlinear function are utilized,and Bayes rule is used to perfect the system,which results in a remarkable increase in generalization ability and applicability of the system.
