摘要
广东珠海—中山天然气管道工程所经地段以海积冲积平原为主,软弱土的厚度为3.0～12.0m,管道完工后某些地段的管道有明显的上浮现象,文章根据软弱土灵敏度的大小,针对该管道上浮段和未上浮段分别提出了管道抗浮计算公式,对于软弱土地区管道抗浮设计及勘察具有参考价值。
Guangdong Zhuhai-Zhongshan natural gas pipeline passes mainly through the marine built alluvial plain with the soft soil depths of 3.0 ～12.0 m. Since the pipeline project was completed, obvious pipeline floating phenomena at some sites have occurred. In this paper, the floatage resistance calculation formulas for floated pipeline and for non-floated pipeline are respectively offered according to the soft soil sensitivities. It is helpful to floatage resistance design and survey of similar pipeline projects in soft soil areas.
