地震环境下地下管廊动态响应及减震措施研究

地震作为一种常见的自然灾害,对地下管廊的安全运行具有较大影响。本文通过研究地震环境下地下管廊的动态响应和减震措施,旨在为提高地下管廊的抗震性能提供理论支持和实践指导。本文以兰州市七里河区马滩综合管廊为例,从地震环境下地下管廊动态响应分析了地震对地下管廊的影响,从结构设计、减震装置、柔性管道和连接方式、监测和维护等四个方面提出减震措施,可有效降低地震对地下管廊的影响,提高其安全性和稳定性。

Earthquakes,as a common natural disaster,have a significant impact on the safe operation of underground pipe galleries.This article studies the dynamic response and seismic reduction measures of underground pipe galleries in earthquake environments,and aims to provide theoretical support and practical guidance for improving the seismic performance of underground pipe galleries.The article takes the Matan comprehensive pipe gallery in Qilihe District,Lanzhou City as an example,analyzes the impact of earthquakes on underground pipe galleries from the dynamic response of underground pipe galleries in earthquake environments.Then,seismic reduction measures are proposed from four aspects:structural design,seismic reduction devices,flexible pipes and connection methods,as well as monitoring and maintenance,which can effectively reduce the impact of earthquakes on underground pipe galleries,and improve their safety and stability.
