Abstract

Abstract

In order to understand the engineering properties of cohesive clay in the foundation of Sutong highway large bridge in the lower reaches of Yangtze River, the deformation and strength parameters were studied based on a large number of geotechnical tests and regression analysis method.Study result shows that the variation coefficients of deformation and strength parameters for cohesive clay are larger than those of physical parameters; there is good exponential correlativity between compression module and three physical parameters that are natural pore-solid ratio, natural water content and dry density, the correlativity coefficients are more than 0.87;there is linear correlativity between compression coefficient and three physical parameters, the correlativity coefficients are more than 0.91;there is better exponential correlativity between cohesion and three physical parameters, their correlativity coefficients are more than 0.84;while the correlativity between internal friction angle and three physical parameters is bad, their linear correlativity coefficients are less than 0.41.
