摘要
在特定砂卵石地层中有关深基坑侧向变形时空演化特征的研究还不多见。以成都某地铁车站深基坑为例,通过变形监测数据分析基坑各代表性围护桩单体的侧向变形过程及其在平面和竖向上的空间差异,总结成都深基坑变形的时空演化特征和规律,并给出其设计和安全施工要点。
The study on deformation of pit excavation in pebbly sand is seldom researched. The deep-foundation pit of a subway station of Chendu Metro was selected as a case to analyse its deforming process during excavation and the deformation difference on horizontal outline and on vertical direction along the typical retaining piles on the base of the deformation monitoring data, and finally summarize the time-space evolution disciplines of the deep-foundation pit in Chcngdu and give some valuable advices for the pit retaining structure design and the safety construction.
