| 摘 要： | 根据实际工程,运用FLAC-3D软件建立了深基坑工程的数值分析模型,就基坑坑底加固措施对基坑本身及其周边环境的影响进行了分析.建议坑底加固区的合理宽度为1倍基坑开挖深度左右,从而在较大程度上控制基坑坑壁的位移.

| Abstract: | In order to ensure the stability of deep excavation pit and the embankment near national railways,this paper has established a numerical analysis model for deep foundation engineering by FLAC-3D software.carried out a series of comparison and analysis on the impact of pit bottom reinforcement measures on pit itself and the environment based on the actual engineering,puts forward a reasonable bottom reinforced area which is 1 time the width of the excavating depth,to control more effectively the excavation p... |
