The gravel soil caused by slope and proluvial deposits has characteristics such as complex material composition

irregular structural distribution

and difficulty in collecting samples

which brings certain difficulties to the research of this type of soil.This article analyzes a large amount of in-situ testing and geotechnical test data conducted in the Bangguo Converter Station Project

and proposes the relationship between the bearing capacity of the foundation and the number of cone dynamic penetration tests.At the same time

the empirical formula of the horizontal push shear test was revised

and a suggestion for the value of shear resistance parameters was finally proposed.
