Analysis on factors affecting stress distribution in rock wall under blasting loads
摘要
Abstract
FEM analyzing models are established for various factors affecting the dynamic stress distribution in rock wall. These factors include widths of rock wall,mechanical parameters,and the excavating order of rock wall. The stress distribution in the rock wall is calculated and analyzed under the blasting loads with FEM software ANSYS5.5.2. The magnifying effect of velocity along the height of rock wall are also discussed. The results show that widths of rock wall,mechanical parameters,and the excavating order of rock wall all have great effects on the dynamic stress distribution in rock wall. These factors must be strictly controlled for the safety and stability of rock wall in the construction.关键词
