为提高矩形盾构隧道管片接缝的防水性能,本文依托某城市火车站矩形盾构隧道工程,利用
ABAQUS 有限元分析软件建立弹性密封垫模型并优选了密封垫截面型式,结果表明:(1)截面型式C、D、E 密
封垫在正常压缩工况与错位压缩工况下均能满足张开度7 mm、错位量12 mm 的防水要求,截面型式A、B 防
水性能较差;(2)正常压缩工况各截面型式密封垫防水性能总体上从高到低依次为C/E、D、B、A;错位压缩
工况各截面型式密封垫防水性能总体上从高到低依次为C/D、E、B、A。研究结果可为类似工程的管片接缝
防水设计提供参考。
- Abstract:
-
In order to improve the waterproofness of the joints between segments for rectangular shield tunnel,on the
basis of the railway station rectangular shield tunnel project in a city,we used the ABAQUS finite element analysis
software to establish the elastic gasket model and select the optimal gasket section type. The results show that:
(1)Sealing gaskets of section types C,D and E can meet the waterproof requirements of 7 mm opening and 12 mm
misalignment under normal compression conditions and misalignment compression conditions,while sealing gaskets of
section types A and B have poor waterproofness.(2)Under normal compression conditions,the overall waterproofness
of gaskets of different section types is C/E,D,B and A from good to poor. Under the misalignment compression
conditions,the overall waterproofness of gaskets of different section types is C/D,E,B and A from good to poor. The
research results can provide a reference for the waterproof design of segment joints in similar projects.
