深厚软土地区基坑大变形机理与控制对策研究
摘要:针对软土地区深基坑工程“时空效应”显著的特点，结合南京河西地区某深基坑工程案例，分析深厚软土条件下基坑产生大变形的机理，通过采取支撑加固、限载、卸载、隔离桩、配筋垫层、底板先行施工等综合控制措施，有效控制了基坑变形速率，保证基坑施工得以安全顺利实施。
Abstract:Considering the "time and space effect" of deep excavations in soft soil area is significant,based on excavations case in Hexi area,Nanjing,the mechanism of large deformation of excavations under deep soft soil is analyzed.Comprehensive control measures such as supporting reinforcement,load limiting,unloading,isolation piles,reinforcement and thickening cushion,and floor construction are adopted,the deformation rate of excavations is effective controlled,which guarantees the evcavations to be carried out safely and smoothly.It provides reference for deformation control of excavations engineering in similar soft soil area.
