【Abstract】 The influence of the ground settlement induced by excavation of deep foundation pit on the surrounding structures and buildings can not be ignored in design. The traditional calculating method is improved in this paper according to the engineering experience in the area of Tianjin. The ground settlement caused by the excavation of deep foundation pit for some practical projects is calculated by the improved method. The calculation results agree well with the observed data.更多还原
