The affected factors to the whisht intensity of pipeline is analysed in two aspects: defectiveness and non. In the non-defectiveness aspect, the tranversing pipeline is considered as thin-wall container, and the annulus stress emerged from inner pressure as main stress on base of stress influence colligated with temperature and inner pressure, then amends it with the axis orientation stress, with the 4th intensity theory, we can calculate the whisht intensity of river tranversing oil pipeline.

从有缺陷和无缺陷两个方面对管道静强度的影响因素进行了分析，在无缺陷穿越管道的静强度分析中，是将穿越管道视为薄壁容器，并在综合考虑温度和内压对管道的应力影响的基础上，把由内压引起的环向应力当作主要应力，再用轴向应力加以修正，根据强度理论计算相当应力，从而实现了穿越河流输油管道的静强度计算。
