大量试验证实盾构隧道开挖可引起管线与土体界面脱空和土体屈服现象。基于无拉力Winkler地基及管线地基承载力理论,将界面脱空和土体屈服判据条件引入管土线弹性相互作用分析;由此推导了考虑界面脱空和土体屈服影响的管土非线性相互作用计算方法,并与模型试验结果对比验证了其适用性。参数分析发现,界面脱空范围随管线抗弯刚度增大而拓宽;受管土分离和地基屈服影响,管线响应随地层损失呈非线性变化;在土体脱空和屈服范围较大时,其对管线响应影响显著,忽略该效应将导致计算管线挠度和弯矩过于保守。

随着碳青霉烯类抗菌药物的广泛使用,耐碳青霉烯肺炎克雷伯菌(carbapenem resistant klebsiella pneumoniae,CRKP)已成为全球公共卫生的“紧急”优先事项。CRKP所致的感染与高死亡率相关,是医院感染的重要病原体。CRKP主要的耐药机制是碳青霉烯酶的产生,临床可用的有效抗菌药物有限,目前部分新型抗菌药物对CRKP有较高的活性及安全性。本文对CRKP的耐药机制、新型抗菌药物的应用进行评述,以供临床参考与借鉴。

为系统研究盾构隧道开挖引起的土与管线相互作用问题,揭示盾构掘进过程中地层位移的复杂性及管土界面接触状态变化规律,采用缩尺物理模型试验方法,制作可监测管线沉降、管底脱空和管底土压的模型管线,通过拔管的方式来模拟盾构隧道掘进过程,依次开展盾构掘进引起砂土深层沉降试验、管线响应与管土脱空试验。试验结果表明:1)盾构隧道开挖引起的深层土体沉降仍符合高斯分布,沉降槽宽度参数与地层损失率均随地层埋深呈现非线性变化。2)试验证实了在较大的地层损失条件下容易出现管土脱空现象,隧道开挖引起的最大管线变形和管底脱空值均随管线埋深增大而增大,而管底脱空范围递减。3)当管线挠曲较小时,管线与土体保持紧密接触;随着盾构掘进,在开挖面距管线1.5倍隧道直径处其底部开始出现脱空现象,开挖面距离管线1倍隧道直径至离开管线1倍隧道直径是脱空的主要发展阶段。

To solve the flexible Job Shop scheduling order problem of dual-resource constraints , on the basis of considering the production capacity constraints of the workshop and operators, the mathematical description of the problem is given. An improved hybrid immune simulated annealing algorithm is proposed and applied to the scheduling order problem of dual-resource constraints. The global-searching ability is improved. Encoding method and activation decoding algorithm based on the process are used to ensure that any arrangement of chromosomes can produce a feasible solution, reduce the search region, and improve search efficiency. By changing the amount of resources to compare the simulation, the effect of the constraints of the total resources on scheduling order is better concluded. The experimental results show that it is feasible and effectual to solve the scheduling order problem of dual-resource constraints by the improved hybrid immune simulated annealing algorithm.
