摘要：传统、新型岩土工程问题诸如压缩空气含水层储能、充气截排水技术、二氧化碳地质封存、油气地下储备工程等均涉及气水两相流与应力耦合.针对这一工程实际,根据非饱和土气水两相渗流-应力弱耦合理论,开发了基于TOUGH2与FLAC3D的气水两相渗流-应力耦合计算搭接程序.该计算程序能够较为真实地模拟气水两相渗流问题,能够探讨流动过程中气水的相互作用及其对过程的影响.程序考虑了气水两相渗流与土体骨架变形直接的相互作用,反映了这一过程中孔隙度、渗透率、毛管压力和土体物理力学参数的变化,实现了更为完善的气水两相渗流与应力弱耦合分析.通过与经典的排水试验和模型试验对比,验证了该程序可以较为准确地模拟气水两相流-应力之间的相互作用.

摘要：电弧等离子体与气体之间的相互作用机理研究一直在低温等离子领域受到关注。为了获得比较均匀的大面积直流电弧等离子流,设计了一种利用外磁场驱动电弧旋转的等离子发生器。利用高速摄影技术研究了大气压条件下氩电弧等离子体在弧室中的运动情况,得到了典型的螺旋型电弧照片,分析了外部磁场对电弧运动形状、电弧电压的影响和弧根附近的气流扰动情况,认为磁场分布的不均匀性是导致电弧形状多样性和不稳定性的主要原因,而阴极烧蚀引起了弧根区气流扰动的不对称性。

摘要：通过Revit进行3D虚拟建造获得了单体建筑的建筑模型、结构模型和项目的室外道路、边坡模型,在此基础上,链接所有模型到同一模型中检查了不同专业间存在的冲突,得到了以下结论:通过虚拟建造能很好帮助发现和解决传统2维施工图纸存在的问题,从而提高施工图纸的质量。通过将图纸问题分为4类进行统计分析发现,还未出图的施工图纸质量较差,若发现和解决不及时会对施工进度和成本造成较大影响。
