Abstract According to geological characteristics of recently sedimentary layer in Huaibei plain，such as existence of different soil and calcareous concretions，a large number of dynamic plate loading tests are carried out relying on highways under construction. The range and variation of dynamic deformation modulus are analyzed for different soils，and distribution characteristics of are discussed for different geological area in Huaibei plain. On this basis，relationships between the and penetration resistance，bearing capacity of foundation are established through static cone penetration tests，screw plate tests and plate loading tests. Studies show that，dynamic plate loading test is a fast and convenient in situ test，and mechanics characteristics and regularity of foundation soil can be reflected well by ，which has good relativity with penetration resistance of value and bearing capacity of the foundation. can be used in highway engineering as a foundation bearing capacity determination index.

Key words： soil mechanics dynamic plate loading test dynamic deformation modulus bearing capacity of foundation correlation
