Study on Interaction Mechanism of Natural Gas Pipe-Landslide System Reinforced by Micropile Groups Based on Model Test

Abstract: Natural gas pipeline projects in mountainous areas are inevitably affected by geological disasters such as landslides, which pose a serious threat to the safe operation of pipelines along the routes crossing landslide areas. In this paper, based on a pipe-landslide project in a mountainous area in southwest China, the interaction mechanism and failure evolution process of the landslide-pipeline system reinforced by two kinds of micropiles are studied through indoor large-scale physical model tests, and some su… Show more

“…Gu studied the effects of lateral landslides on X80 PHGS with corrosion defects, and identified landslide displacement as the most sensitive factor [10]. Wu used large-scale model tests to analyze the interaction and synergistic deformation mechanism of landslides, micropiles, and pipelines under the action of external forces [11]. Zhu et al analyzed the effects of pipeline corrosion size, operating internal pressure, and corrosion location on the ultimate bearing capacity of buried pipelines with corrosion defects, and derived the ultimate load prediction formula [12].…”

“…Currently, the anti-slip mechanism and design of the MP have been studied and analyzed using model tests [5,6] and numerical simulations [7,8]. Numerical methods, such as the finite difference method (FLAC) and finite element method (ABAQUS, ANSYS) [9,10], are commonly used in the simulation of MPs, focusing on pile parameters, reinforcement position, soil arching effect, and other aspects.…”
