In this paper, the limit load of buried pipe, that is used in Nanjing city nature gas using engineering, was studied by finite element analysis under various groundsill character, pedestal angle and ground pressure, and the risk assessment for this piping was performed. The limit load of buried pipe was measured by experiments. The research contents and results were as follows:(1) With FEA method, the effects of various groundsill character, pedestal angle and ground pressure on the limit load of buried pipe were studied.

And detailedly analyzing reasons including these problems, it is can be found that not thinking of the slope of pipeline and the friction in the process of production water hammer pressure functions, but thinking of the effect of the slope pipeline in the process of production the consequent water hammer calculative continuity function , which results in the inconsequent illogicality in the whole process of producing.

对这些问题存在的原因进行了详细分析，发现在当前推导水击压强公式的过程中没有考虑管道的倾斜度和摩擦阻力的影响，而在后面水击计算的连续性方程的推导过程中则考虑了管道的倾斜度，这就导致了在当前连续性方程的整个推导过程中前后矛盾的不合理现象。

Secondly, detailedly analyzing reasons inducing these problems, author finds it is that not thinking of the slope of pipeline and the friction in the process of producing water hammer pressure functions, but, thinking of the effect of the slope of pipeline in the process of producing the consequent water hammer calculative continuity function, which results in the inconsequent illogicality in the whole process of producing.

接着，对这些问题存在的原因进行了详细分析，发现在当前推导水击压强公式的过程中没有考虑管道的倾斜度和摩擦阻力的影响，而在后面水击计算的连续性方程的推导过程中则考虑了管道的倾斜度，这就导致了在当前连续性方程的整个推导过程中前后矛盾的不合理现象。
