摘要
针对软土地区基坑工程中存在“时空效应”的特点,结合轨道交通6号线某明挖区间基坑工程实例,对基坑变形实测数据进行了分析探讨,并在此基础上考虑开挖过程的时间和空间影响因素,采用杆系有限元方法对该基坑进行了计算。经过和实测数据的比较,进一步证实了在软土地区基坑设计计算中考虑时空效应的必要性。希望对软土地区类似的基坑工程提供有益的借鉴。
Based on the time-space effect characteristics of the pit foundation in soft soils, combining a practical engineering example of metro line 6, a lot of field data were gathered and analyzed. And the time-space effect was taken into account, an usual plane finite bar element method was used to calculate the pit deformation. Comparison between the test results and the field data indicates that the time-space effect is essential to the design and calculation of the pit foundation in soft soils. This work is significant to the study of pit foundation in soft soils.
