混凝土結構軟巖大巷斷裂過程非線性數值模擬

Nonlinear Numerical Simulation for the Concrete Zone of Fracture in the Process of the Developing Load at Soft-Rock Roadway

摘要: 引入斷裂力學原理,以某混凝土結構副大巷中復雜結構為研究對象,通過相似模擬實驗和現場觀測等手段對有關材料物理力學參數進行識別和修正,結合現場礦壓觀測結果和相似材料模擬試驗結果,對該巷道內部應力破壞敏感部位的內力和變形機理進行了系統的分析、模擬計算.研究結果對現場支護設計、維護加固和提高巖層穩定程度具有重要的意義.

Abstract: Inducting rupture mechanics principles, comprhensive research on the inside of stress distortion and its mechanism has been developed at auxiliary concrete structures roadway. Both situation result and resemble simulacruxn ending, the property parameters of support material have been identified. It is boortan to design, reinforce, enhance the strata cohesion in practical project.
