文摘

Improved analytical models for lateral dynamic soil–pile interaction are presented. The soil is treated as a continuum using a more accurate Tajimi type solution. Detailed assessment of static and dynamic Winkler moduli in literature is performed. The performance of the Winkler model is checked against the accurate proposed model. A new simple expression for a dynamic Winkler modulus (spring, dashpot) is proposed.
