“…The backfill soil's cohesion is 15 kPa, the friction angle is 15°, the elastic modulus is 20 MPa, the density is 1840 kg/m 3 , and Poisson's ratio is 0.3. The rockfall and stratum are the same material, which is limestone with a cohesion of 6.72 MPa, friction angle of 42°, elastic modulus of 28.5 GPa, density of 2090 kg/m 3 , and Poisson's ratio of 0.29 [9]. Dilation angle of the soil and rock is assumed to be zero for cases considered in this paper.…”

“…More recently, using FE models with shell elements and continuum solid soil elements, Kaya et al, simulated the failure behavior of a welded steel pipe at Kullar fault crossing [26]. Zhang et al discussed the collapse behavior of pipeline buried in rock under strike-slip fault movement and reverse fault displacements [27,28]. Vazouras conducted series of numerical models to investigate the failure behavior of pipeline under strike-slip fault movement in detail [29][30][31][32].…”

Abstract:As a typical hazard threat for buried pipelines, an active fault can induce large plastic deformation in a pipe, leading to rupture failure. The mechanical behavior of high-strength X80 pipeline subjected to strike-slip fault displacements was investigated in detail in the presented study with parametric analysis performed by the finite element model, which simulates pipe and soil constraints on pipe by shell and nonlinear spring elements respectively. Accuracy of the numerical model was validated by previous full-scale experimental results. Insight of local buckling response of high-strength pipe under compressive strike-slip fault was revealed. Effects of the pipe-fault intersection angle, pipe operation pressure, pipe wall thickness, soil parameters and pipe buried depth on critical section axial force in buckled area, critical fault displacement, critical compressive strain and post buckling response were elucidated comprehensively. In addition, feasibility of some common buckling failure criteria (i.e., the CSA Z662 model proposed by Canadian Standard association, the UOA model proposed by University of Alberta and the CRES-GB50470 model proposed by Center of Reliable Energy System) was discussed by comparing with numerical results. This study can be referenced for performance-based design and assessment of buried high-strength pipe in geo-hazard areas.

“…Xie et al [11,12] conducted a comprehensive numerical modeling of buried HDPE pipelines subjected to normal and strike-slip faulting. Zhang et al [13] investigated Bulking behavior of buried gas pipeline under strike-slip fault displacement by finite element method, studying the effects of internal pressure, radius to thickness ratio and fault displacement on buckling mode. Rahman and Taniyama [14] employed DEM and finite element method (FEM) to investigate the force-displacement relation between pipes and particles in the axial and vertical directions for fault movement.…”

Buried pipelines, transporting fuels, inevitably face active faults when they pass through various seismic regions. These faults may damage the pipelines severely; hence numerous analytical, physical and numerical studies have been conducted with their own pros and cons to investigate the pipeline response due to the faulting. In the present study, an innovative combination of centrifuge and numerical modeling methods has been employed to overcome the geometrical limitation of the small scale physical modeling. Then, it is applied for investigation of buried pipelines response due to reverse faulting. Initially, two centrifuge tests with the fixed end pipelines have been conducted and employed as the benchmarks for the verification of a numerical model. Then, the calibrated numerical model has been used to develop the novel pipeline spring-like end connection system which is supposed to represent the response of the omitted pipeline parts. Eventually, a centrifuge test was conducted, employing the novel end connection system which verified the proper performance of the system. Then, the model is employed for investigation of buried pipelines response due to reverse faulting and the results are also presented.
