粘土卵石层中的土压盾构施工技术

On geostatic shield construction technology of clay gravel layer

结合以往盾构施工经验,针对粘土卵石层中盾构掘进施工中存在的磨损严重、易"泥饼"等问题,通过工程实例介绍了土压盾构穿过粘土卵石层的一些施工经验和技术措施,以指导实践。

Combining with the shield construction experience,aiming at the problems in the shield tunneling construction of the clay gravel layer,including the serious abrasion and common sludge cakes,the paper according to the engineering examples,introduces some construction experience and technical measures in the shield tunneling through the clay gravel layer,so as to direct the practice.
