| 摘 要： | 地铁是对变形要求极为严格的建筑,在紧邻已运营的地铁处开挖的深基坑对地铁以及周围建筑产生的影响的分析预测显得尤为重要。通过理论计算结果和实际监测结果反分析对比得出针对本工程的沉降修正系数。选取不同工况,对基坑开挖结束后的大型工程桩降水开挖对地铁结构的影响进行了预测,提出了在工程的后续施工中应采取的措施。所述方法对本工程的施工和分析类似工程有参考价值。 |
| 关 键 词： | 深基坑降水 地铁结构 沉降预测 |

| Abstract: | Metro structure has a very strict requirement on the deformation,so it is very important to analyze and predict influence of deep foundation pit excavation on adjacent operation metro structure and surrounding constructions.By using back analysis based on theoretical calculation and actual monitoring results,the settlement correction coefficient in this project was obtained.With different working conditions,influence of large engineering pile dewatering and excavation in foundation pit on metro structure was predicted,and the follow-up countermeasures were proposed.This method is valuable for analysis of this project and similar constructions. |
| Keywords: | dewatering of foundation pit metro structure subsidence prediction |
