摘要：
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. © 2016, Chinese Society of Civil Engineering.
