为提高隧道立拱质量和效率,解决人工立拱在隧道施工中存在的搭接部位不牢靠、错位以及劳动强度大等问题,基于新型多功能作业台车,结合装配式隧道及地下工程建造技术理念,设计一种适用于机械化装配的折叠式钢拱架。依托新乌鞘岭隧道进口段机械化装配施工,对折叠式钢拱架的装配性能进行现场试验并对其承载特性进行数值分析,结果表明: 1)折叠式钢拱架的装配性能可以满足隧道机械化装配的要求; 2)承载性能可以满足设计要求,且试验段隧道拱顶沉降为706 mm; 3)提高了钢拱架安装质量和效率,降低了工人的劳动强度。最后,总结折叠式钢拱架立拱关键技术要点。 相似文献

Feature Abstracting and Identification of Acoustic Target in the Battle Field Based on EMD 总被引:1,自引:0,他引:1
The method of empirical mode decomposition(EMD) was used for the signal processing and featureing of acoustic target of battle field. According to the signal's characteristics of different targets, some feature vectors in token of the target properties were constructed and abstracted. In the basis of feature abstracting and statistic analysis for large amount of sample signal of the targets, using the maximum subjection classification method based on the fuzzy synthesis judgment, the three typical acoustic target helicopter, tank and traffic vehicle were recognized. 相似文献
