SOIL PRESSURE AROUND BURIED PIPES

THE DISTRIBUTION OF PRESSURE IS EXAMINED AROUND A BURIED PIPE. IT SUGGESTS THAT PRESENT METHODS DANGEROUSLY UNDERESTIMATE THE PRESSURE INVOLVED. IN THE INITIAL PERIOD OF THE LIFE OF THE PIPELINE, IT IS CONTENDED THAT THE PRESSURES ON ITS SIDES CAN REACH VALUES APPROACHING THE PASSIVE LEVEL AND THOSE OVER ITS CROWN WILL BE HIGHER THAN THOSE DUE TO THE SIMPLE OVERBURDEN. IT IS FURTHER SUGGESTED THAT AS TIME PROGRESSES, THE LATERAL PRESSURES ARE REDUCED TO VALUES COMMENSURATE WITH THE EARTH PRESSURE IN THE "AT-REST" CONDITION, WHILE THE VERTICAL PRESSURES TEND TOWARD THE SIMPLE OVERBURDEN LEVEL. /RRL/A/
