摘要
中俄原油管道漠大线工程是中国四大原油进口战略通道之一,该工程也是我国首条通过多年冻土区、林区的大口径原油管道。文章结合该工程,在不同温度条件下,对施工现场的2根桩基础进行了竖向承载力自平衡试验研究。试验得到了不同温度下桩基础的竖向极限承载力、桩身轴力、土层摩阻力分布规律等成果,并对不同温度下桩基础的承载性能进行了对比分析。
Mo-Da line is one of the import strategy channels in Chinese four crude oil channels.This project is also the first large-diameter curde oil pipeline in frozen ground area in China. In this paper, combined with the project, 2 piles were tested by the self-balanced load test method under the condition of different temperatures in the construction site. The vertical ultimate bearing capacity of piles, axial force of piles, soil friction distribution regularity was given. The bearing capacity of pile foundation under the condition of different temperatures was analyzed.
