flexible pipe when buried, it is required that the pipe be more yielding than the embedment soil surrounding it.This is the source of flexible pipe\u2019s external-load-carrying capacity. Under soil load, the pipe tends to deflect. The vertical diameter is compressed and the horizontal diameter expands by approximately the same amount in both directions When the horizontal diameter expands, it engages the passive resistance of the soil support at the\nsides of the pipe. At the same time, the compression of the vertical diameter relieves the pipe of the major portion of the vertical soil load, which is then carried by the surrounding soil through the mechanism of an arching action over the pipeBy unibell
