Abstract

Through field test, physical and mechanical properties, mechanical composition, characteristics and compaction properties of the Yellow River alluvial silt soil were analyzed. The result shows that silt inside air compaction was difficult to discharge due to the influence of soil particle composition and low content of clay. As a result, the uneven settlement deformation of subgrade is obvious and the stability of silty soil water is not enough. The rainfall is frequent. Moisture content of soil is too high. It is difficult to dry field soil. The construction period is short. In order to speed up the pace of construction, we proposed the over-wet silt optimal multiple water control technology.
