Model test on filtration fabrics of drainage board in reinforcement of soft soil foundation

  • 摘要: 排水板外起过滤作用的滤膜种类多,性能差别大,为探究不同排水板滤膜在真空加固软基过程中的性能差别,设计室内单井模型试验,对3种排水板滤膜进行研究,研究表明:①等效孔径较大的排水板滤膜抗淤堵能力强,加固效果好;②纤维强度较高的排水板滤膜抵抗受力变形能力强,抗淤堵性能好;③加固过程中,竖向排水体附近土粒发生流失,滤膜孔径越大、距离滤膜越近土粒流失越多;④实际工程中,在满足保土性要求前提下,建议优先考虑纤维力学强度高、等效孔径较大的滤膜。
    Abstract: Filter fabrics are not unified. To explore the influence of different filter fabrics on vacuum preloading, model tests on single well are performed to study three kind of filter fabrics. The results show: (1) The filter fabrics with large aperture have strong ability to resist siltation, so the effect of disposing soft soil is better. (2) The filter fabrics with strong fibers can resist mechanical deformation, and soft foundation is improved well. (3) During the tests, the soil next to the vertical drainage channel runs away, and the larger the aperture and the shorter, the distance the greater the loss of soil. (4) In practical engineering, under the premise that the soil requirements are satisfied, it is suggested, that the membrane filter with fiber with high mechanical strength and large equivalent aperture should be used.
