“…The investigation carried out by Joshi et al on the effects of reverse fault rupture on buried pipelines showed that the capacity of buried pipeline to accommodate the reverse fault rupture could be increased if the pipe crossing angle with respect to fault line became near-parallel [7]. On the other hand, with current knowledge, it is not always possible to determine the precise place of fault and its path and therefore pipe crossing angle with respect to fault line (β).…”

“…On the other hand, with current knowledge, it is not always possible to determine the precise place of fault and its path and therefore pipe crossing angle with respect to fault line (β). Moreover, even the passage of buried pipeline parallel to fault line (figure 1a) which was recommended by joshi et al [7], can cause severe damages to buried pipelines in some critical conditions. In this research, by inspiring from researches of Fadaee et al [8], [9] with using a thick diaphragm-type soil bentonite wall (SBW) in a specific distance with buried pipelines which is parallel with fault line (figure 1a), SBW absorbs the deformation resulted from any possible reverse fault rupture and mitigates the damages caused to pipelines cross section (figure 2).…”

Buried pipelines influenced by coal mining subsidence will deform and generate additional stress during surface deformation. On the basis of the coordinating deformation relationship between buried pipeline and its surrounding soils, a stress analysis method of a buried pipeline induced by mining was proposed. e buried pipeline additional stresses were analyzed; meanwhile, a corresponding analysis process of the pipeline stresses was also presented during mining subsidence. Furthermore, based on the ground subsidence along the pipeline predicted in advance by the probability integral method, the additional stresses and Von Mises equivalent stresses and their distributions along the buried pipeline induced by the exploitation of a coal mining working face named 14101 were obtained. Meanwhile, a comparative analysis of additional stresses between simulation and analytical calculation was performed for the deep analysis and reliability of the results presented by the proposed methodology in this paper. e proposed method provides references for analysis of the additional stress and safety of buried pipelines under the influence of mining subsidence.

“…Local buckling is an ultimate state of pipelines under complex loading conditions caused by subsidence, earthquake and landslides, etc., in geological hazard zones (Han et al 2012;Shantanu et al 2011). Local gross deformation in wrinkled sections can do harm to loading-carrying capacity and even damage structure integrity of pipelines (Dama et al 2007).…”

Pipelines in geological disaster regions typically suffer the risk of local buckling failure because of slender structure and complex load. This paper is meant to reveal the local buckling behavior of buried pipelines with a large diameter and high strength, which are under different conditions, including pure bending and bending combined with internal pressure. Finite element analysis was built according to previous data to study local buckling behavior of pressurized and unpressurized pipes under bending conditions and their differences in local buckling failure modes. In parametric analysis, a series of parameters, including pipe geometrical dimension, pipe material properties and internal pressure, were selected to study their influences on the critical bending moment, critical compressive stress and critical compressive strain of pipes. Especially the hardening exponent of pipe material was introduced to the parameter analysis by using the Ramberg-Osgood constitutive model. Results showed that geometrical dimensions, material and internal pressure can exert similar effects on the critical bending moment and critical compressive stress, which have different, even reverse effects on the critical compressive strain. Based on these analyses, more accurate design models of critical bending moment and critical compressive stress have been proposed for high-strength pipelines under bending conditions, which provide theoretical methods for highstrength pipeline engineering.
