Abstract

With the human activities gradually into the ocean, especially the implementation of the strategy of the Belt and Road, engineering construction will be more and more involved in the coral sand foundation, and the survey of foundation design specification, has not yet listed coral reef types of geotechnical, field test research on characteristics of coral sand foundation scholars both at home and abroad. However, after the coral reefs are artificially disturbed and blown into the land area, the mixed land foundation with coarse and fine grained soil is formed. In this paper, the characteristics of non-uniform and weak interbedded coral soil are obtained by dynamic field touchdown, pit exploration, particle analysis and Rayleigh wave method. Through triaxial shear tests with different porosity ratios, the results show that the shear strength index of coral sand is higher than that of natural silt sand and silt, and the coralline sand has certain cohesion. Through field loading plate test and dynamic contrast analysis, the reasonable loading plate impact depth, dynamic agent number and coral hybrid bearing capacity of soil foundation has good correlation, and through the analysis of dynamic agent number and the foundation bearing capacity, dynamic agent number and the experience formula of the modulus of deformation, and research has certain reference value to similar projects.
