Oil and gas pipelines, as vital arteries for energy transportation, play a crucial role in ensuring the supply of energy. However, under harsh geological conditions external forces, pipeline's anti-corrosion layer is susceptible to damage, particularly destruction caused by forces such rockfall. This study focuses on performance new type material-Fiber Reinforced Polymer (FRP) coating-under rockfall scratch, compares it with Polyethylene (3PE) coating. By establishing three-dimensional...
The spinning circular solar sail is a promising spacecraft for long-duration missions. This work reveals its structural dynamic and stability behavior under the periodically time-varying radiation pressure gravitational force. geometric stiffness generated by centrifugal force due to coupling effect between deformation are taken into account. von Kármán plate theory adopted neglecting high-frequency in-plane vibrations considering of internal on transverse vibration. partial differential...
In this paper, the finite element analysis method is used to extensively study response of rockfall impact on pipelines with different erosion resistant coating. Based numerical results, safety pipeline comprehensively evaluated. Firstly, through establishment detailed and models, materials speeds simulated. The results indicate that can cause significant stress concentration deformation in damage With increment speed, also increases significantly, exhibit varying conditions, it found...
摘要: 加固结构所的抗滑力常被简化为恒定值,不能反映其随时间的变化.为了更准确评估地震下桩-锚组合结构加固边坡的稳定性,引入非线性的模型,实现了抗滑力的实时更新.推导了安全系数和位移计算公式,讨论了结构系数对评估结果的影响.结果表明:(1)引入指数非线性模型后,抗滑桩和锚索力均表现出明显的时间效应.屈服加速度随结构的变形而增大.(2)地震初期抗滑桩无加固作用.随着边坡滑动,抗滑桩的力快速增长,最终起主导作用.(3)将结构的抗滑力等效为固定值虽然简化了计算,但是忽略了达到设计值所需的位移,这可能导致边坡的危险性被低估.在加固设计时,应该考虑抗滑力的变化. 关键词: 抗滑桩 / 锚索 组合结构 永久位移法 地震荷载 工程地质
In order to analyze the impact of near-fault pulse ground motions on slope, method seismic vulnerability analysis based IDA is introduced into stability evaluation. Taking slope reinforced by stabilizing piles as an example, a typical model established. The performance divided four stages: basically intact, partial damage, severe damage and overall instability. A large number calculations are used compare instability probability slopes with far-field motions. results show that: 1)...
