摘　　要：结合上海某一圆形超深基坑的工程实例,介绍了在松软土地质条件、承压地下水、周边环境复杂等复杂地质条件下圆形超深基坑的半逆筑法施工技术。根据开挖过程中的施工监测,重点对承压水和围护结构变形内力的信息化施工监测,分析圆形超深基坑的力学性状和施工工法,取得了较多有益的工程经验。Based on the project of a circular deep foundation excavation in Shanghai, the technique of half-inverted construction on circular deep foundation excavation was introduced under complex geological conditions, such as soft clay, confined water and complex circumjacent condition, and so on. Base on the results of construction supervision during excavation, the informative supervision of retaining structure transformation and the deep well point operation was emphasized, The mechanical performance and construction technique, were analyzed and much useful experience was obtained.
