摘要
Abstract
Due to the large north-south span in China,the temperature problem has to be controlled during the construction process of the pipe jacking method.Many on-site test results have shown that the temperature change of the pipeline can have an impact on itself and the surrounding soil.This problem was simulated using AbaqusCAE finite element numerical simulation software.The simulation results showed that the expansion amplitude of the steel top pipe joint and the surrounding soil was large in the horizontal direction and small in the vertical direction under low temperature conditions.Moreover,under the simulated physical conditions,it was concluded that the expansion amplitude in the horizontal direction was about 1.75 times that in the vertical direction.关键词
