Soil Classification and Site Variability Analysis Based on CPT—A Case Study in the Yellow River Subaquatic Delta, China

The Yellow River Delta is located at the junction of and Bohai. impact function from river dynamics ocean tides make soil composition distribution in this area substantially complicated. In order to test variation layers Delta, were classified was calculated using cone penetration (CPT). following conclusions drawn: (1) measured mainly composed sensitive fine-grained soil, accounting for about 70% all types, content far-sea position higher than that offshore direction perpendicular coastline. (2) It has a high vertical variability index (VVI) near-shore location, above 45%, low far coast, generally below 20%. (3) horizontal (HVI) changes significantly near it remains 45% area.
