Analysis on Adaptability of Shield Machine in Xincheng Road Utility Tunnel Project

摘要:

盾构法作为城市综合管廊暗挖施工的重要方法,随着城市化的不断深入,所面临的施工现场条件也越来越复杂。本文通过新城路综合管廊工程的施工重点、难点与应对措施,论证土压平衡式盾构机在珠三角深厚软土层及各种现场工况下的适用性,为类似工程提供参考意义。

Abstract:

As an important method of underground excavation of urban utility tunnel, the shield method faces more and more complex construction site conditions with the deepening of urbanization. Through the construction essentials, difficulties and countermeasures of Xincheng Road Utility Tunnel Project, the applicability of earth pressure balance shield machine in deep soft soil layer and various field working conditions in the Pearl River Delta is demonstrated, which can provide the reference for similar projects.
