Abstract

Today, buried pipes can be considered one of the main substantial infrastructures which has significant role with human life. Such projects serve purposes, including, drain lines, water mains, sewage lines, telephone and electrical conduits, highway and railway culverts, gas and liquid-petroleum lines, coal slurry lines, subway tunnels and various other special functions. This paper focuses on reviewing, describing and understanding the static and dynamic behavior of underground pipes during earthquake events and at rest condition involving seismic vulnerability causes, failure modes of pipelines and loads subjected on pipes. A quick glance on the assisting factors that reduce the pipes breakage due to earthquakes is presented. Also, this paper reviews some previous studies about performance of underground pipes under seismic loads. It was concluded that the soil density has a significant impact on the displacements corresponding to the maximum force. For shallow pipes to obtain the minimum lateral displacement value, it is recommended to use soil density medium to dense state. It was observed also there is a relationship between the spacing of pipes and its displacement so; to obtain the minimum displacement the spacing between the pipes must be at least equal to the pipe diameter.

Highlights

To raise the human lifestyle due to increasing of the population, pipelines below ground surface were utilized many decades ago
Days underground surface pipelines provide in extensive extent of request like drinking water pipes, sewer/drain lines, electrical/telephone services, lines of oil, channel, lines of coal slurry, as well as newly lines of heat distribution, tunnels of subway [1]
The findings revealed that increasing height of backfill or maximum acceleration ground significantly improves the buried pipe's earthquake response

Summary

Introduction

To raise the human lifestyle due to increasing of the population, pipelines below ground surface were utilized many decades ago. Days underground surface pipelines provide in extensive extent of request like drinking water pipes, sewer/drain lines, electrical/telephone services, lines of oil, channel, lines of coal slurry, as well as newly lines of heat distribution, tunnels of subway [1]. The protection of pipes as a goal cannot be achieved unless their actual performance is well known and taken into account [2]. This paper focuses on reviewing the basic information about the dynamic performance and response of underground pipelines.
