Available in PDF, EPUB and Kindle. Book excerpt: With this fact established, a hypothesis of the action of such a culvert under an actual earth embankment was devised and each loaded pipe was analyzed to determine its horizontal and vertical deflections, its bending moments, and its tangential thrusts. The hypothesis assumes a uniformly distributed vertical load and vertical reaction, and a passive pressure against the sides of the pipe distributed approximately parabolically over the middle 100 degrees of the pipe sides. The passive pressure is postulated to be proportional in magnitude to the lateral movement of the sides of the pipe. Extensive full-scale experiments on flexible culverts ranging from 36 to 60 in. in diameter were conducted. The pipes were loaded by embankments of several kinds of soil 15 and 16 ft. high, without traffic loads, and the loads, deflections, radial pressures, settlements and other pertinent data were observed. These experiments amply verify the design formula developed from the load hypothesis.
