摘要
根据非特征线应力边界条件的显示解析表达式 ,明确给出了岩土材料滑移线场理论中应力间断线上的应力条件、应力间断值及其位置 ,使得锐角楔体极限荷载等问题的求解更简单。
The problem about stress discontinuity often exists when the limit load is solved using the slip line method or the lower boundary method of limit analysis.The stress discontinuity is expressed using the stress discontinuity line in the slip line field.The stress discontinuity line is not stress character line based on the characters of stress character line.Therefore, the stress condition, stress discontinuity value & position of the stress discontinuity line on the slip line field theory for geo-technical materials is clearly given in this paper based on the analytical expression of non-characteristic line stress boundary condition.Thus,the solving such as the limit load of acute wedge becomes simpler and more convenient.
