减小爆炸破坏的有效方法是在爆炸点与建筑物之间设置一道防爆墙。采用LS-DYNA软件借助已有文献推荐的方法建立数值分析模型。研究了不同药量爆炸荷载下钢筋混凝土防爆墙(RCBW)的破坏过程。提出了4种不同方案的钢板混凝土防爆墙并对其抗爆性能进行分析、排序。最后,利用RC框架作为防护对象,分析不同钢板混凝土防爆墙的防爆效果。结果表明:爆炸荷载下钢筋混凝土防爆墙的破坏过程分为3个阶段,处于第3阶段的钢筋混凝土防爆墙发生严重的破坏。相比较于钢筋混凝土防爆墙,4种不同方案的钢板混凝土防爆墙的抗爆性能均有明显的提高,其中双面钢板混凝土防爆墙的防爆效果最好。爆炸荷载下,经双面钢板混凝土防爆墙防护后的RC框架柱没有发生任何破坏,而经其他3种方案防护的框架柱均有一定程度的塑性损伤。

实现碳达峰碳中和目标既是应对气候变化的必由之路,也是中国彰显大国责任担当和推动构建人类命运共同体的迫切需要。中国目前碳封存选址大多都集中在陆地,并且主要以气态CO_(2)或者液态CO_(2)的方式进行碳封存。陆地的碳封存潜力不及海洋,而且前者对于储层的地质条件和作业条件要求均较高。海洋是地球上最大的活跃碳库,碳封存潜力巨大,目前中国已建成第一个海上碳封存项目——“恩平15-1”CO_(2)封存示范项目。为了加快推进CO_(2)海洋封存目标的实现,提出了CO_(2)水合物固态封存的新思路,探索了海洋碳封存的整体路径。研究结果表明:①基于甲烷水合物开发的逆向思维,以及CO_(2)水合物形成条件远不及甲烷水合物苛刻的特点,可以将CO_(2)注入海底形成CO_(2)水合物碳矿;②基于“固态流化”法的逆向原理及思维将液态CO_(2)直接注入甲烷水合物层及其下伏层的泥砂中,不仅可以利用CO_(2)置换开发甲烷水合物,而且还能在海底浅层形成CO_(2)水合物进而实现碳封存;③利用现有油气田开发平台和设备,选择有利于CO_(2)封存的地质构造和咸水层,有望实现油气田开发和海洋碳封存的协同发展。结论认为,该方法已经通过了实验室可行性验证,有望为未来碳捕集、利用与封存(CCUS)提供新的解决方案。

机器学习通常从数据中挖掘潜在的模式与规则,容易受到数据的影响而产生诸如过拟合、欠拟合等现象,进而影响学习模型的泛化与鲁棒性能。从对抗仿真测试的角度考察SVM可能存在的脆弱不稳定性,采用的对抗仿真策略是通过选择性地污染训练样本标签,模拟攻击SVM分类器使其性能退化,以测试其对训练样本的依赖性。为探究SVM分类器在不同样本组合攻击下的性能损失上限,设计了最小攻击代价-最大攻击成效这一对矛盾目标,构建了SVM仿真测试的多目标优化模型。该模型本质上是一种典型的多目标组合优化问题,可采用适当的多目标演化算法求解目标间的一组非支配解集,揭示分类器在不同样本组合攻击下的分类性能表现。在人工及真实数据集上的仿真对比实验结果表明:所提方法能够一次性生成不同攻击水平下的最优攻击样本组合,取得最大的分类性能损失,更能全面测试SVM分类器性能的稳定性。
