摘要

为了解决城市地铁施工中复合式TBM刀盘结泥饼或刀盘被糊的问题，主要从渣土改良、复合式TBM掘进参数控制、刀盘冷却循环水温度等因素和工程地质因素进行分析刀盘结泥饼的原因。并采取了对渣土改良、调整复合式TBM掘进参数、降低外循环水温度等措施，确保了复合式TBM刀盘不结泥饼和刀盘在轻度结泥饼的状态下不影响复合式TBM推进。

Abstract

Muck conditioning, tunneling parameters control of composite TBM, temperature of cooling water for cutterhead and project geological condition are analyzed in this paper, in the interest of solving mud cake in cutterhead during composite TBM tunneling in urban metro. Then, a compositive system for ensuing smoothly TBM tunnellling without mud cake or with little mud cake is proposed, including muck conditioning, tunneling parameters adjustment of composite TBM and cooler circulated cooling water.

Key words： composite TBM; sandy mudstone; causes for mud cake in cutterhead; precautionary measures
