一种适用于沿海地区的暗柱叠合装配式地下综合管廊研究

Design and performance research of superimposed assembly utility tunnel with dark column use for coastal areas

以福建沿海地区的地下综合管廊为工程背景,对国内目前常见的整体预制或者现场装配式管廊进行方案比选,提出了一种带暗柱叠合装配式的地下综合管廊设计方案。进行了理论计算分析和试验加载研究,指导完成了现场的试验段施工。通过研究表明,该暗柱叠合装配式管廊方案受力性能良好,在沿海软土地质区域的工程实践应用中是可行的。

This paper takes the utility tunnel in Fujian coastal area as the engineering background,compares and selects the schemes of integral prefabrication or field assembly utility tunnel that commonly used in China.Propose a design scheme of superimposed assembly utility tunnel with dark column.Conduct theoretical calculation and analysis and experimental loading research,than guide the construction of test section.It indicates that this programme is fine in mechanical performance.It’s feasible to use in soft soil of coastal areas.
