In recent years, with the development of the national economy, large span bridges, docks,offshore platform and other construction develop quickly. SPC-RC mixing pile in thesestructures have been widely used. Therefore, it is necessary to research on SPC-RC pile. Inthis thesis, the rule of steel corrosion in the coupling of erosion environment and load areobtained by test. The seismic performance of offshore platform has been numerical analyzedby using Abaqus. The main content of this thesis are as follows:Firstly, the rule of steel corrosion in different load has been obtained by test.Secondly, the steel casing increase the shear bearing capacity of the pile by result ofnumerical simulation of static analysis to SPC-RC pile.Then, the seismic dynamic response of offshore platform are numerical modeled usingdifferent earthquake load by Abaqus, including acceleration, relative displacement, bendingmoment and shearing force of the SPC-RC pile. The top of the pile and pile at some rangeunder the ground surface line are the most dangerous position under the load of theearthquake by the result of numerical analysis. In addition, the steel casing increase theseismic capability of the pile.
