摘要/Abstract

摘要： 为进一步提升隧道智能建造水平，加快施工进度，以量化设计为前提，全过程质量控制标准为基础，提出隧道支护分序技术。以宜兴高铁隧道智能建造试验段为对象，对不同围岩的分序支护设计方案、施工期的安全性、进度提升效果等进行研究，得出以下结论： 1）在保证支护结构强度增长速度不低于围岩压力增长速度时，初期支护分序施工是可行的，可以保证施工安全。2）一序初期支护应充分发挥围岩的自承载作用，同时满足围岩压力增长和支护强度匹配要求，补强初期支护滞后距离在满足多工序作业循环所需施工设备排布空间要求的同时，尽可能缩短布置长度，以利于发挥初期支护的早承载功能。3）分序支护建立在量化设计和精细化施工基础上，因此需要严格控制隧道施工质量和支护时机。4）以宜兴铁路350 km/h单洞双线隧道智能化工区试验段为例，Ⅲa衬砌A型分序、B型分序，Ⅳa衬砌C型分序方案对应的施工进度可分别提高46.5%、14.7%、9.36%。

Abstract:

Sequential supporting technology is proposed based on the quantitative design and the quality control standard of the whole construction process, in order to further improve the intelligent construction level of the tunnel and accelerate the construction advance rates. With the intelligent construction of the trial sections of tunnels on YichangXingshan highspeed railway as the research object, the design of the sequential supporting for different surrounding rocks, the safety during the construction and the advance rate improvement effect are comprehensively studied, and the following conclusions are drawn: (1) When the growing rate of the strength of the supporting structure is not lower than that of the pressure of the surrounding rock, it is feasible to construct sequential primary supporting and the construction safety can be ensured. (2) Sequence I primary supporting shall give full play to the selfbearing function of the surrounding rock and meet the requirements of the matching between the surrounding rock pressure growing and the support strength. The lag distance of Sequence Ⅱ reinforcing primary supporting shall be as short as possible while meeting the requirements of the space required by the construction equipment needed for multiprocess operation cycles, so as to give full play to the early loadbearing function of the primary support. (3) Sequential supporting is based on quantitative design and precise construction, so it is necessary to strictly control the tunnel construction quality and the supporting opportunity. (4) Sequential supporting is applied in the trial sections of tunnels on YichangXingshan highspeed railway, and the construction advance rates of Ⅲa Type A, Ⅲa Type B, and Ⅳa Type C sequential supporting are increased by 46.5 %, 14.7 %, and 9.36 % respectively.
