| 新建地鐵車站上穿既有地鐵隧道結(jié)構(gòu)上浮變形預(yù)測(51 卷) |
| 英文標(biāo)題 |
| Prediction of lifting and deformation of existing metro tunnel induced by newly-built metro station located above it |
| 摘要 |
| 依托北京地鐵4號線西單車站上穿既有1號線區(qū)間隧道工程，分析了地鐵上穿工程中所面臨的風(fēng)險點，建立FLAC3D數(shù)值計算模型，對既有線的上浮變形規(guī)律進(jìn)行了研究，并預(yù)測了既有線隧道結(jié)構(gòu)的最大上浮變形值為2.9 mm。預(yù)測值與現(xiàn)場監(jiān)控量測結(jié)果2.3 mm比較接近，且縱向變形曲線形態(tài)相 |
