| 盾構(gòu)隧道管片上浮機(jī)理及控制技術(shù)(49 卷) |
| 英文標(biāo)題 |
| Mechanism concerning floating up of segmental lining of shield-driven tunnel and its control |
| 摘要 |
| 基于Maag球面擴(kuò)散公式，通過引入等效孔隙率替代土體本身的孔隙率，對盾構(gòu)隧道壁后注漿的滲透范圍及對管片造成的上浮力進(jìn)行了理論推導(dǎo)，并從注漿方法、漿液選擇、注漿參數(shù)控制、管片上覆土及盾構(gòu)姿態(tài)等多方面提出了控制隧道管片上浮的針對性措施。 |
