Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering detection and testing, and in particular relates to an indoor simulation test method for fill foundation seepage and settlement deformation. Background technique [0002] The filling foundation is an artificial foundation formed by layering and compacting general fine-grained soil or coarse-grained soil to the target compaction degree (dry density) by various compaction methods. At present, two methods are mainly used to study the seepage problem of the fill foundation: one is to measure the permeability coefficient based on the indoor small-scale soil column seepage test and the soil-water characteristic curve, and use the seepage theory and numerical simulation method to analyze the saturation and unsaturation of the foundation However, due to the artificial disturbance and representativeness of small soil columns, the measured seepage parameters cannot accurately reflect the en...
