摘 要: | 结合具体工程实例,利用有限元分析方法对邻近地铁隧道的基坑围护变形控制要求进行研究。分析结果表明:针对不同的围护结构变形控制标准,地铁隧道结构的位移量亦随之发生变化。当围护结构位移值达到40mm时,隧道结构的位移将达到甚至超过地铁隧道的变形控制限值;当围护结构的变形值达到20mm时,隧道结构的位移相对较小,可更为有效地保护隧道结构的安全。

Analysis on deformation control of deep foundation pit adjacent to metro tunnel |

Abstract: | Combined with practical engineering examples, the finite element analysis method is used to analyze on deformation control of deep foundation pit adjacent to metro tunnel.The results show that the displacement of metro tunnel structure changes with different deformation control standards of the foundation pit.When the displacement value reaches 40mm, the displacement of the tunnel structure will reach even more than the subway tunnel deformation control limit.When the retaining structure deformation reaches 20mm, the displacement of the tunnel structure is relatively small, can more effectively protect the safety of the tunnel structure. |
