In order to study the dynamic response of pipe-piercing dike under seismic load, taking a dike-crossing project in Guangdong Province as the research object, considering the interaction between pipeline and soil, a three-dimensional numerical simulation model of pipeline-dike was established. The simulation of foundation boundary spring-damper was realized through secondary development. The results show that under the action of 0.1g seismic acceleration, the vertical displacement of the dike increases with the increase of the height of the dike and decreases along the axis of the dike. The maximum displacement at the top of the pipeline is greater than that at the left and right ends. The stress distribution law of the pipeline is consistent with displacement, and the maximum stress of the pipeline is proportional to the thickness of the soil cover layer. The Mises stress at each point of the midpoint section of the pipeline through the dike is the largest, and the seismic capacity of the middle section of the dike is relatively weak. The stress and displacement near the midpoint section of the pipeline in the dike should be monitored in the seismic design of the subsequent dike project. This study has important practical significance to ensure the safe and stable operation of the dike-crossing project.

以广东省某穿管堤防为例,考虑管道与土体间的相互作用,建立管道-堤防三维数值仿真模型,通过二次开发实现地基边界弹簧-阻尼器的模拟,探究地震作用下堤防与管道的动力响应规律。结果表明,在0.1g地震加速度作用下,堤防竖向位移沿堤防高度的增加而增大,沿轴线方向逐渐减小;管道顶部及底部位移最大值均大于左右两端;管道应力分布规律与位移变化相似,穿堤管道中部断面的各点Mises应力最大,管道应力最值与土体覆盖层厚度成正比,说明堤防和管道中间段位置抗震能力较薄弱,后续穿堤工程的抗震设计中应重点监测堤内管道中部断面附近应力和位移,为保障穿堤工程安全稳定运行有重要的现实意义。

以广东省某穿管堤防为例,考虑管道与土体间的相互作用,建立管道-堤防三维数值仿真模型,通过二次开发实现地基边界弹簧-阻尼器的模拟,探究地震作用下堤防与管道的动力响应规律。结果表明,在0.1g地震加速度作用下,堤防竖向位移沿堤防高度的增加而增大,沿轴线方向逐渐减小;管道顶部及底部位移最大值均大于左右两端;管道应力分布规律与位移变化相似,穿堤管道中部断面的各点Mises应力最大,管道应力最值与土体覆盖层厚度成正比,说明堤防和管道中间段位置抗震能力较薄弱,后续穿堤工程的抗震设计中应重点监测堤内管道中部断面附近应力和位移,为保障穿堤工程安全稳定运行有重要的现实意义。

In order to study the dynamic response of pipe-piercing dike under seismic load, taking a dike-crossing project in Guangdong Province as the research object, considering the interaction between pipeline and soil, a three-dimensional numerical simulation model of pipeline-dike was established. The simulation of foundation boundary spring-damper was realized through secondary development. The results show that under the action of 0.1g seismic acceleration, the vertical displacement of the dike increases with the increase of the height of the dike and decreases along the axis of the dike. The maximum displacement at the top of the pipeline is greater than that at the left and right ends. The stress distribution law of the pipeline is consistent with displacement, and the maximum stress of the pipeline is proportional to the thickness of the soil cover layer. The Mises stress at each point of the midpoint section of the pipeline through the dike is the largest, and the seismic capacity of the middle section of the dike is relatively weak. The stress and displacement near the midpoint section of the pipeline in the dike should be monitored in the seismic design of the subsequent dike project. This study has important practical significance to ensure the safe and stable operation of the dike-crossing project.
