摘　　要：遭遇洪水冲刷而漂浮于河水中的管道对整条管道的安全运行存在很大的潜在威胁。对其进行沉管治理,对沉降管道进行力学分析,找出危险截面。在此基础上,针对沉管过程中管道受力复杂且难以控制从而导致管道破坏的问题,采用应力应变实时监控技术监测整个沉管过程中危险截面的实时应力应变情况,基于监测到的应力值提出相应的措施以控制沉管过程中管道危险截面的应力于许用范围之内。结果表明:在整个沉管过程中,应力应变监控技术为管道的安全沉降起到了指导作用。The pipeline floating in the river because of flood will produce a big potential threat to the safe operation of the entire pipeline. In this case, the dangerous sections of the sunken pipeline are found by mechanics analysis, and the stress and strain on the dangerous sections are monitored in the sinking process of the pipeline. Based on the monitored stress and strain values, some appropriate countermeasures are proposed to control the stress of the dangerous section within the allowable range in the sinking process of the pipeline. The application result shows that, the stress and strain monitoring technology plays a guiding rule for the safe sinking of the pipeline.
