Research on Optimization of Construction Scheme for Super Large Foundation Pit of Urban Railway Parking Lot
Affected by the epidemic,the construction progress of the foundation pit of the Shanghai urban railway airport connection link Shenkun Road parking lot is seriously lagging behind.The parking lot is the key node of the opening of the airport connection line.In order to ensure the overall delivery of the project on time,it is necessary to optimize the construction scheme of the super-large foundation pit.With safety as the primary consideration of foundation pit engineering,through technological innovation,the synchronous operation of group pits is realized to the greatest extent.At the same time,a series of measures are adopted,such as optimizing the support system,adjusting the local support arrangement,adding the steel beam hoisting platform and introducing genetic algorithm,the difficulties and pain points in the construction process are solved,so as to effectively improve the construction progress,ensure the construction period,and achieve good social and economic benefits.
