Abstract Pipeline transportation is the mode of transport for oil and natural gas existing in the safest, most economic, environmental damage is minimized. However, the underground pipeline design and protection methods still lack, Of buried pipeline, the mechanical characteristics of the analysis has been calculated accurately. A number of buried pipeline in the use frequently damaged, resulting in leakage of spend a lot of manpower and resources to maintenance, Clearly this state of affairs and prospects for the development of underground pipeline is incompatible. Therefore, this article on long-distance pipeline buried in the structure of the force and deformation are analyzed. In this paper, I use the elasticity approach to long-distance pipeline buried by the role of internal pressure of the mechanical properties were discussed. Solving a long-distance pipeline buried in the internal pressure of the stress components, deformation and displacement of the weight component. The fourth strength theory and the use of long-distance pipeline buried in the risk of internal pressure when the intensity of checking points. Papers use MATLAB7.0 software applications of the results obtained by the numerical analysis. And the use of the GUIDE tools MATLAB7.0 produced a calculation of long-distance pipeline buried the stress components as well as the danger point calibration applications. This paper presents the research methods and results, buried for the strength of long-distance pipeline design to provide a theoretical basis and a practical calculation software.
