| 摘 要： | 与钻爆法开挖地下工程相比,TBM法具有其独特的优势,然而TBM对各种不良地质条件的适应能力却不如钻爆法那样全面,结合TBM施工的工程实践,在深入分析多种不良地质条件对双护盾TBM施工的严重影响后,论述了不良地质条件中的相关工程地质问题,总结了应对不良地质条件的对策,阐明TBM法施工的成败与前期地质勘察精度有直接的和重要的关系。分析结果对今后类似地下工程在选择TBM施工时具有一定的参考意义。

| Abstract: | Compared with drilling ＆ bursting method,TBM method has a lot of particular advantages for excavation underground engineering. TBM can not fit with all kinds of adverse geological conditions just like drilling ＆ bursting method. Based on TBM excavation engineering practice, some problems existed in adverse geological conditions are expounded after in-depth analysis of the effect of adverse geological conditions on double shield TBM. The countermeasures are also summarized facing adverse geological conditions. The success of TBM construction is of direct and important connection with the geological exploration precision. The result has great reference to TBM construction of the similar underground projects. |
