根据蒋明镜等所提出天然结构性砂土微观胶结模型及微观胶结试验结果,将该模型引入离散元商业软件PFC2D,进行能源土双轴试验离散元数值模拟分析,并同Masui等[6]能源土三轴试验结果进行对比分析,结果表明,蒋明镜等所提出胶结模型能够较好的模拟水合物的微观胶结力学行为,水合物胶结的存在对能源土强度具有一定的贡献。 According to the result of microscopic cementing experiment of natural structured sand made by Jiang Mingjing et al., This model was introduced into discrete element commercial software PFC2D to carry out the discrete element numerical simulation of biaxial energy soil test. In the same way as Masui et al. [6] Soil triaxial test results were compared and analyzed. The results show that the cementing model proposed by Jiang Mingjing et al. Can better simulate the micro-cementation behavior of hydrates, and the hydration cementation has a certain contribution to the strength of energy source soil.
