基于流固耦合的临江深基坑开挖变形规律分析

DEFORMATION REGULARITY ANALYSIS BASED ON FLUID-STRUCTURE INTERACTION FOR A RIVERSIDE DEEP FOUNDATION PIT’S EXCAVATION

江深基坑的主要影响因素为基坑与江堤的距离、江水高度和土体性质。基于流固耦合的分析方法,分析3种因素对临江深基坑开挖变形的影响规律。对比3种因素对临江深基坑开挖变形的影响,分析其对临江深基坑开挖变形的敏感性程度。

According to the characteristics of riverside deep foundation pit, the riverside deep foundation pifs main influencing factors are summarized as follows: the distance between the foundation pit and the embankment, the height of the river water and the nature of the soil. Based on the fluid-structure interaction, method three factors have been analyzed to reveal how the deep foundation pit changes its shape when the excavation goes on. Comparing three factors' difference working on deep foundation pit's excavation, reveal the deep foundation pit's sensitivity to three factors.
