| Abstract: | In this paper, a three-dimensional finite ele-
ment 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 characteris-
tics for the drilling rig foundation, the effect of basic frame
on the dynamic characteristics of the drilling rig founda-
tion 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. |
