研究成果
1、提出了帶裂隙脆性材料在壓縮載荷下的破壞準則,即:
其中f 是裂紋表面摩擦係數, 是裂紋傾角, 是含裂紋材料的單軸抗壓強度, 和 是主應力。經簡化該準則可轉化為最大剪應力準則,在無裂隙時該準則轉化為著名的庫倫摩爾準則;
2、首次成功將AUTODYN軟體開發套用於岩石動態破壞的數值模擬研究中,成功模擬了岩石、混凝土等脆性材料的動態破壞過程,給出了其破壞機理。在該方面發表的論文多次被引用,其中兩篇論文在國際岩石力學期刊中為Most Cited Paper;
3、給出了地球上部岩體中應力大小的範圍,並成功解釋了如下地球物理現象:即在地殼表面附近,水平應力與垂直應力比值 ()分布在一個較廣範圍內,但在深部區域,卻分布在豎直線 周圍一個狹小範圍內。
4、成功地利用數值模擬方法給出了岩體開挖後出現分區破裂化的機理,及出現的條件。岩體開挖後出現分區破裂化現象是困擾地下岩體工程界多年的重大難題。
5、提出了新的任意四邊形的有限差分法。
6、提出了岩石等脆性材料在爆炸載荷下動態斷裂韌度測試新方法。
