| 4 | 帕劳国预应力连续箱梁长期下挠分析显示文摘帕劳共和国科罗尔岛-巴伦尔图阿普岛桥(简称KB桥)为主跨241 m的预应力混凝土箱梁,通车后KB桥发生长期下挠,严重影响其正常运营,最后垮塌,其教训值得反思。该桥于1977竣工,运营18年后挠度达到1.61 m,1996年对该桥进行了体外预应力加固,却在加固后3个月发生垮塌。挠度分析结果表明:传统的梁理论与三维空间分析相比,误差高达20%,且宽跨比越大,误差越大。三维有限元空间分析采用多种徐变收缩计算模型:美国ACI模型、日本JSCE模型、CEB-FIP模型和GL模型,其挠度计算值要比(18年后)实测值低50%~70%,预测的变形也与实测不符;预应力损失计算值为22%~24%,远低于实测值50%。唯一基于理论的B3模型,采用经验值参数计算得到预应力损失40%,18年后挠度计算值比实测值低42%。如果根据长期实测值调整输入参数,结果可与实际更符合。对于早期挠度及其预测,B3模型能够合理地考虑因截面厚度差异产生的收缩和干燥徐变的速率差异。此外,B3模型还可考虑温度差异和顶板可能发生的开裂。 | 叶华文 王力武 曲浩博 Bazant Z P Yu Q Li G H | 2017 | 中外公路2017,37,5: | 5 |

| 6 | Influence of Fe Addition on Products of Self-Propagating High-Temperature Synthesis Reaction in 3Ti-Si-2C System显示文摘Influence of Fe addition on products of self-propagating high-temperature synthesis (SHS) reaction in 3Ti-Si-2C system was investigated in the present study. Without Fe addition, Ti5Si3 and TiC are the dominant phases along with a small amount of Ti3SiC2 phase and unreacted C left in the final products. As Fe content ranges from 10% to 30%, the products consist of TiC, Ti5Si3, Fe2Ti and unreacted C, but no trace of Ti3SiC2 phase is detected. Furthermore, the amounts of both Fe2Ti and C phases increase with Fe content increasing. Addition of Fe has a great effect on the reaction route and significantly restrains the formation of Ti3SiC2 during the combustion synthesis process, and therefore, the SHS is not an effective fabrication technique to synthesize the ternary Ti3SiC2 ceramic in either 3Ti-Si-2C or Fe-3Ti-Si-2C system. Besides, without Fe addition, Ti5Si3 presents as the coarse irregular appearance with an obviously sintered morphology. In contrast, the shape of Ti5Si3 exhibits more and more spherical (cobblestone-like) and the surface becomes increasingly smooth, because the amount of liquids formed during the SHS reaction increases with the increase of Fe content. On the other hand, with Fe content increasing from 0 to 30 wt.%, the particulate size of TiC decreases from more than 5 μm to 1 μm or less, mainly due to the fact that the combustion temperature decreases with the increase of Fe content in the preforms. | Guan Q L Wang H Y Li S L Si W P Jiang Q C | 2009 | 稀有金属材料与工程2009,38,A03: | 2 |
