“…According to the research of Zhang 39 and Liu et al, 40 the rubber gasket has obvious nonlinear elastic behavior. The constitutive response of rubber in the 3D finite element method (FEM) model is represented by the Mooney–Rivlin model, 41 which is widely used in engineering, and its strain energy function equation is as follows:

U goodbreak= C_{10} ((), I_{1} goodbreak- 3) goodbreak+ C_{01} ((), I_{2} goodbreak- 3) goodbreak+ \frac{1}{D_{1}} {(J - 1)}^{2},

where U is the strain energy, I 1 and I 2 are the invariants of the deformation tensor of the rubber material, J is the compression coefficient of the rubber material, C 10 and C 01 are material parameters of the Mooney–Rivlin model, and D 1 is a constant parameter.…”

Buried pipelines inevitably pass through complicated geological areas because of their wide coverage. A three‐dimensional numerical model subjected to normal fault considering the geometrical and mechanical properties of the bell–spigot joint in Prestressed Concrete Cylinder Pipe (PCCP) is proposed to analyze the effects of location, displacement, and dip angle of fault on the rotation angle and axial translation of bell–spigot joints as well as the effects on the deformation of pipe bodies. At a dip angle of 90°, the maximum joint rotation angle and pipe deformation are larger when the relative location of fault and joints is under the odd configuration than under the even configuration. The kinematic characteristics of joints and the mechanical characteristics of pipe bodies on the moving side are opposite to those on the stationary side. The amount of offset has a significant impact on the longitudinal response of the pipeline. The rotation angle and axial translation of the joints on both sides of the fault increase with increasing fault displacement. When the offset reaches 270 mm, the joint rotation angle is 1.05°, which exceeds the specification limit of 1°. On the basis of numerical results, the simplified estimate of the maximum rotation angle is improved, and the error is reduced to 3%. With the increase of fault dip angle, the affected area gradually moves left to the fixed part. When the dip angle is 75°–90°, the pipeline longitudinal response is large, which is unfavorable to the pipeline safety.

Prestressed concrete cylinder pipe (PCCP) is widely used in hydraulic engineering. The bell-and-spigot joint is a weak point along a PCCP pipeline, since damage of joint can affect the operation of the whole pipeline. In this paper, a threedimensional numerical model of buried PCCP, considering the simulation of rubber gasket in bell-and-spigot joint is established. The fluid-structure coupling of PCCP is accomplished using the Mesh-based parallel Code Coupling Interface (MpCCI), where the pipe and the surrounding soil are characterized in the software ABAQUS, and the pressurized water is modeled in the software FLUENT. The force and rotation angle at joints of PCCP under different conditions, including surcharge load, loading location, cover depth, and internal pressure, are analyzed. It is shown that the rotation angle of joint exceeds the allowable value, when the surcharge load is greater than 180 kPa. Compared with the effect of surcharge load, the offset distance (i.e., distance between the loading position and the pipe axis) has a greater influence on the development of horizontal displacement and rotation angle. As the offset distance increases, both the horizontal displacement and rotation angle at joints increase first, and they decrease after the peak.

The discussion will then be published in print, along with the authors' closure, if any, approximately nine months after the print publication.
