Abstract
Numerical results for strike-slip (horizontal) fault crossings are presented, using advanced three-dimensional finite element models. The model consists of a soil prism and employs shell elements for the pipeline and “brick” continuum elements for the soil. Appropriate boundary conditions are imposed, so that continuity of the pipeline outside the prism is taken into account. Some indicative mitigation measures are also proposed. In the final part of the chapter, the important issue of buried pipeline bends (elbows) is treated. Individual bends with axial tension are analyzed first, to examine their mechanical behavior and to establish a load-displacement relationship. Subsequently, using those load-displacement relationships, a strike-slip fault crossing case is analyzed, for the purpose of examining the effect of bends on pipeline response. It is concluded that, the proper use of bends at a distance from the fault line, may be beneficial for the pipeline, reducing the strain developed in the pipeline wall.
