大口径急曲线钢筋混凝土顶管管节接缝张开量分析

Analysis of Splaying Amount of Joints of Segments of Large-diameter Large- curvature Reinforcement Concrete Pushing-pipe

大口径急曲线顶管工法在我国首次使用 ,在国际上也很少见。本文介绍管节接缝张开量的监测方法 ,并利用梁 -接头不连续模型对其进行模拟分析。实践证明 。

The construction method of large diameter large curvature pushing pipe is first used in China and has been used rarely in other countries.In this article,authors introduce the monitoring method of splaying amount of joints of segments and make simulative analysis with the beam joint non continuous model.It is proved that the beam joint non continuous model can to some extend simulate the true splaying states of joints of segments in the construction of pushing pipes.
