Abstract: This paper analyzed the cause of circumferential crack of embedded pipe below dam and gave a calculation method on its expansion crack distance and axial crack resistance in the situation of varying temperature and earth pressure. Further more, correlative computation formula was advanced for reference.

摘要： 分析了坝下埋管运行后产生环向裂缝的原因,建立了考虑变温和土压力联合作用下的埋管伸缩缝间距与轴向抗裂验算的计算方法,并给出了相应计算公式,方法可供设计人员参考?
