| 摘 要： | 万家寨引黄工程南干线隧洞, 利用双护盾TBM 施工隧洞, 具有隧洞长、埋深大、地质条件复杂等特点, 有较多不良地质构造, 对工程结构稳定不利, 处理也困难; 另外, 隧洞内豆砾石灌浆时, 如能设置止浆环, 对提高灌浆质量有重要意义。为解决这些问题, 提出了利用空腹管片衬砌技术方案, 针对断层、裂隙处理设置混凝土塞的措施, 对侧壁溶洞建立处理工作面的方法。用此方法还可以在Ⅰ～ Ⅱ围岩中临时安装空腹管片, 在完成对TBM 的支撑作用后拆除管片, 岩壁喷混凝土。

| Abstract: | The preliminary design for treatment of fault and improvement of grouting quality in TBM tunnel are presented. Using some hollow segments for support liner,the geological structure,such as fault,crack,or even karst cavity could be easily dealt with.Moreover,the presented method does not hamper TBM′s work. |
