泥水加压式盾构施工技术不仅可以实现水土循环利用,而且还加快了施工进度。因此,它作为一项环保施工技术,近来受到广泛应用。而泥水系统中泥膜的形成对盾构开挖面的稳定性起着极其重要的作用,尤其在均匀系数较小的砂层中,其对开挖面的稳定作用尤其显著。以广州———佛山城际快速轨道交通工程为背景,针对本工程地质特性,介绍了泥膜试验装置及试验过程,并通过该试验对泥膜参数敏感性进行相关分析,得出了一些对盾构施工工程有益的结论。
Slurry pressurized shield construction technology can not only achieve soil and water recycling, but also speed up the construction progress. Therefore, it has been widely used as an environmentally friendly construction technology recently. The formation of clay film in the muddy water system plays an important role in the stability of the excavation surface of the shield, especially in the sand layer with small uniform coefficient, especially for the stability of the excavation surface. Taking the Guangzhou-Foshan inter-city rapid rail transit project as a background, the mud film test device and the test process are introduced according to the geological characteristics of the project. Through the correlation analysis of the mud film parameter sensitivity, some pairs Shield construction project useful conclusions.
