Abstract
In order to improve the construction quality of super deep foundation pit in soft soil area,this paper takes a building project as an example to analyze the surrounding environmental data,horizontal displacement data,vertical displacement data and supporting axial force data of its supporting structure.The results show that with the progress of construction,the building settlement increases rapidly at first,then slowly and then rapidly.The road settlement shows a change law of rapid increase at first and then a slow increase.The maximum building settlement is 24 mm,and the maximum surrounding road settlement is 24.5 mm.The maximum horizontal displacement of the top of the foundation pit support is 46.6 mm,and the maximum vertical displacement of the top of the foundation pit support is 22.5 mm.The groundwater level shows a law of continuous decline,and the maximum variation of the water level reaches 717 mm.All the monitoring data are within the range of de-sign requirements,indicating that the supporting structure and dewatering measures adopted in this project have certain safety and rationality,and have achieved the expected effect of design.关键词
