Some conclusions are drawn from the calculating results: when buried pipes cross fault, pipe's embedded depth should be shallow, and big pipe diameter and thick wall should be selected. Avoid the site where fault moves severe, and select suitable pipe-fault angle. Bigger pipe-soil friction coefficient is helpful for buried pipe crossing fault. Under dynamic loading, buried pipe would first damaged in compressive region of bilateral fault, so special treatment should be done to pipe in bilateral fault region.

依据计算结果分析了各因素对地下管道破坏的影响，并得出几点结论：管土摩擦系数较大情况下，管道破坏较轻；地下管道在穿越断层时，管道宜浅埋，并选取大管径、壁厚的管道；应尽量避开断层错动较大的位置，并选取合适的管道穿越断层角度；在受动荷载作用时，管道在断层两侧受压区先破坏，故在断层两侧要进行特殊处理进行防护。
