摘要
位于软粘土地基中的预应力钢筋混凝土压力管，由于管道设计的不合理以及地基处理的严重质量问题，致使地基土产生严重不均匀沉降，最终导致管道断裂。本文论术了管道产生断裂的原因，并介绍了该管道的修补方法。
located in the soft clay foundation prestressed concrete pressure pipe, due to the irrational and the pipeline design of the foundation to deal with serious quality problems, resulting in serious soil uneven settlement, and ultimately lead to a fracture caused by pipeline. This article on the operation of the pipeline have a fracture of the reasons for, and introduced the method of pipeline repair.
