Aiming at overcoming the low accuracy of traditional slope modeling, a new multi-constraint DSI fitting modeling module was established by introducing multi-constraint discrete smooth interpolation (DSI) algorithm in improving the self-developed 3D numerical analysis system GeoSMA-3D. F...
摘要:隧道周围的断层对隧道的稳定性有很大的影响,应用数值方法分析断层的影响机理,对于隧道工程具有重要的意义。首先,针对隧道岩体的非连续性问题,应用自主开发的GeoSMA-3D系统,采用非连续面网络图模拟真实岩体的几何特征,建立非连续岩体隧道的三维分析模型,根据建立的三维模型确定岩体内部结构面的分步特征;然后,将数值模...

问:一直吃着伊可新的ad钙和迪巧的钙剂没事吧,听别人说这种东西不能常吃(男,8个月) 答:如果没有明显的缺钙表现,钙剂就不要服了,这不是缺钙的表现,这种情况就吃鱼肝油可以了,其他的都不用吃,不要在吃钙了,就口服维生素ad滴剂可以了,睡前不要逗他就可以了。
Using the rock masses of rock discontinuities III and IV as research objects, and utilizing the block cutting and key block identification modules in the GeoSMA-3D (geotechnical structure and model analysis-3D) system, the sliding mass is set as a geometric polyhedron. The...
