中文摘要：

通过对基坑隆起变形产生的原因、抗隆起稳定性、回弹量计算、基坑开挖的时空效应及基坑工程穿越既有建筑物造成的隆起变形等进行分析，指出了基坑隆起变形问题研究中存在的理论分析不够完善，且远落后于工程实践等不足，并对今后有待于开展的工作，如建立适应不同区域土性变化的回弹量计算公式、理论优化基于时空效应的开挖参数、系统化分析开挖对既有建筑物变形的影响等进行了展望．

英文摘要：

The causes for heave deformation of foundation pits, the heave stability, the calculation of rebound, the time- space effects during excavation of foundation pits as well as the heave deformation of the existing buildings intersected by pit excavation were analyzed. It was put forward that the existing theoretical analysis for the heave deformation of foundation pits was deficient and far behind the engineering practices. Some new ideas for further studies were proposed as follows： how to establish formulas for rebound of different soils, theoretical optimization based on excavation parameters of time-space effects, systematic analysis of the influences of excavation on the deformation of the existing structures, etc.
