【Abstract】 s Stated the force-summing status of the buried pipeline under the action of landslide force, determined the location of maximum stress on the pipe section, analyzed the pipe wall stress impact in dependence on the landslide force value, action angle, length of the stressed section etc. An example of pipe wall stress calculation is given. The suggestion of accident prevention and countermeasure after accident is also given.更多还原
