Abstract: In this paper, a three-dimensional finite element for the drilling rig foundation is built for studying the dynamic characteristics and design of the drilling rig foundation. Through analysis of its modes, the dynamic characteristics of the drilling rig foundation are discussed. On the basis of the analysis of the dynamic characteristics for the drilling rig foundation, the effect of basic frame on the dynamic characteristics of the drilling rig foundation is investigated. According to the conclusions drawn from the analysis, the dynamic design or modification of drilling rig foundation structures is made by optimization of frames. The method put forward by the paper can be used in the dynamic design or modification of drilling rig foundation structures.

Key words: drilling rig foundation, basic frame, finite element, dynamic feature, dynamic design
