全断面砂砾地层盾构法施工土体改良技术

Soil Improvement Techniques for Full-face Shield Tunneling through Sand and Gravel Stratum

结合我国地铁隧道施工的重要工法——盾构法,以沈阳地铁1号线小什字街站——滂江街站区间为例,通过对全断面砂砾地层中长距离盾构法施工土体改良技术的分析,为相关工程提供借鉴和参考。

With the development of urban subway construction,shield tunneling has become a major construction method.Taking the transit tunnel from Xiaoshizijie Station to Pangjiangjie Station on Shenyang metro Line 1 as an example,analysis was carried out for the soil improvement techniques for full-face long distance shield driving through sand and gravel stratum,aiming at providing guidelines to related projects.
