摘　　要：上海市域铁路机场联络线申昆路停车场受疫情影响,基坑工程施工进度严重滞后。停车场作为机场联络线开通的关键节点,为保证项目整体按期交付,须对超大基坑工程施工方案进行优化研究。在保证基坑工程安全的前提下,通过技术创新最大程度实现群坑同步作业。同时,通过采取优化支撑体系、调整局部支撑布置、增设钢梁吊装平台、引入遗传算法等一系列措施解决施工过程中的难点、痛点,从而使施工进度得到有效提升,确保了工期,取得了良好的社会效益与经济效益。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.
