Abstract
In order to improve the construction quality of support structure in foundation pit engineering,a high-rise residential building project in Shangrao,Jiangxi Province was used to analyze the mechanical characteristics of support structure by elastic method,determine the support structure design scheme,and evaluate the construction effect of support structure after construction.The practice shows that the stability safety factor of sliding crack surface is 1.306 and the anti-overturning safety factor is 18.45,both of which meet the requirements of standard design.The settlement of deep foundation pit supporting structure ranges from 1.21 to 2.56 mm,and the coefficient of variation ranges from 0.076 to 0.209.The horizontal displacement ranges from0.89 to1.32 mm,and the coefficient of variation ranges from 0.007 to 0.169,all of which are within the allowable value range.It shows that the design scheme of foundation pit support and reinforcement proposed in this case is safe and reliable,and the construction effect is good.关键词
