| Abstract: | Three conditions for the hole wall stabilization of large diameter bored pile-static balance, geological seepage flow and time factor are presented based on theoretical analysis and practical experience. Measures preventing and handling hole caving are given based upon analyzing various factors that influence hole wall stability including objective, technological, environmental and artificial factors. |
