弄清顶进管道的受力状态是管道设计的前提。本文以顶管实践为依据,结合现场量测分析成果,提出管道在顶进中不直接承受土压力作用的结论,为项管设计的荷载组合提供了新观点。
To ascertain the force of the top pipe into the pipeline design is the prerequisite. In this paper, based on the practice of pipe jacking, combined with the results of field measurement and analysis, the conclusion that pipe jacking does not directly receive earth pressure is proposed, which provides a new perspective for the load combination of pipe jacking design.
