Under the hostile submarine conditions,the dynamic characteristics of a submarine fluid conveying pipeline in a suspended span is quiet different from those of a pipeline on land,which was affected by the coupling effect of the flows inside and outside the pipeline.

Fundamental demand and treatment method for underground water delivery pipeline;

This paper introduces the actual operation situation of swift hydraulic pipeline and several energy dissipaters in the extended engineering of Tangjiawan Reservoir of Wutai County.

Stability of pipe conveying fluid under axial load;

Research on natural frequency of pinned-pinned pipe conveying fluid;

Based on the stress anylysis of element,the vibration differential equation of the pipe conveying fluid on elastic foundations is derived,the mode and the nature frequency of the pipe are calculaed by variable-separating method and numerical method.
