摘　　要：结合工程实例,对工程运行期4种不同荷载工况下管坝结合面应力情况和管道外包混凝土以及附近区域坝体混凝土开裂情况的计算分析,对施工期温度作用的影响进行了分析。坝后浅埋式压力钢管具有较高的结构安全度,从保证管道和坝体的安全整体性考虑,提出采用设置键槽或分缝处灌浆以及锚筋的方式加固坝体。Based on engineering examples,the stress situation of the joint surface between the pipe and the dam under four different load conditions during the operation of the project,as well as the cracking of the concrete surrounding the pipeline and the dam body in the nearby area,were calculated and analyzed.At the same time,the influence of temperature during the construction period was analyzed.The conclusion is drawn that the shallow buried pressure steel pipe behind the dam has a high degree of structural safety.From the perspective of ensuring the overall safety of the pipeline and the dam body,it is proposed to reinforce the dam body by setting keyways or grouting at joints and anchoring bars.
