Based on the small deflection beam theory, bending equation with axial tension of suspended pipe partially buried in the linear elastic soil is established. And the corresponding boundary conditions are given according to the stress and deformation characteristics of suspended section and buried section. Then deflection equation for the suspended section is deduced. Afterwards, the stress and c...

Buried pipe leakage can lead to poor heat transfer performance and even system failure. Leakage analysis of buried tube greatly affects the operation condition diagnosis for exchange in tube. In this study, simulation software was applied analyzing process efficiency pipes under different conditions. Moreover, changes outlet temperature, water pressure flow rate were simulated at positions dive...

The mechanism of pipe–soil interaction under frost heaving is complicated due to many factors affecting the system. In order analyze sensitivity various influencing and highlight relationship between pipe’s mechanical characteristics during heaving, a model based on semi-infinite elastic frozen soil foundation developed. Besides, indices characterizing influence their change law are emphaticall...

In order to study the temperature change trend of surrounding geotechnical soil during operation and thermal recovery medium-deep geothermal buried pipe influence on operational stability vertical after recovery. Based data geological stratum in Guanzhong area actual engineering application heating system Xi’an New Area, law heat exchanger is simulated analyzed by FLUENT software. The results s...
