| 摘 要： | 在深埋基础建筑的施工中,基础底面将经历回弹-再压缩-附加沉降的过程。本文通过对具体工程的变形观测,概述了其特点、实施过程中的难点,对现场采集到的数据进行统计、分析,总结出变形量的分布特点及一般规律。同时观测结果验证了对高层建筑部分地基进行加固处理的设计方案明显地改善具有高低差异建筑群的沉降分布状况,大大减少了差异沉降。

| Abstract: | during the period of the foundation pit excavation, the soil under the foundation will experience a procedure including rebound, recompression and additional settlement. This paper introduces the features and the difficulties encountered during the deformation monitoring of a specific project, analyzes the general characteristics and law of the foundation rebound and structural settlement based on the study on the measured data. The monitoring results reflect clearly that the ground improvement measures eff... |
