摘要:

: 盾构选型是盾构隧道施工的关键技术,合理的选型能为后续顺利施工奠定基础。以特拉维夫红线轻轨工程为背景,通过对土层进行试验分析,在充分考虑富水库卡地层土层特性和隧道线形设计的基础上,对盾构刀盘结构、刀具布置、铰接设计、转矩配置等关键问题进行详细研究。结果表明: 1)采用布置有43.18 cm双刃滚刀、开口率为38%的面板式刀盘的土压平衡盾构施工,能顺利完成隧道的掘进; 2)盾体采用主动铰接和被动铰接结合的双铰接设计,能有效解决190 m小半径曲线掘进问题; 3)通过增加驱动电机等措施解决在库卡地层中施工转矩值大的问题,可为今后该地层盾构选型提供参考。

Abstract:

The shield type selection is the key to shield tunneling. Hence, the cutterhead structure, cutter arrangement, hinge design and torque configuration of the shield are studied in detail by analyzing the soil quality of the red line light rail project in Tel Aviv and considering the soil characteristics and the design of tunnel alignment. The study results show that: (1) The tunnel is successfully accomplished by using the EPB shield with a 43.18 cm doubleedged hob and a paneltype cutterhead with an opening rate of 38%. (2) The double hinge design of active and passive hinge is used, which has effectively solved the problem of 190 m small radius curve tunneling. (3) The problem of large construction torque in Kurkar stratum has been solved by adding driving motor, which can provide reference for the type selection of shield in Kurkar stratum in the future.

Key words: Kurkar stratum, small radius curve, shield type selection, torque configuration
