| 橋梁平轉(zhuǎn)施工稱重試驗(yàn)及啟動牽引力計(jì)算探討(51 卷) |
| 英文標(biāo)題 |
| Discussion on weighed test and calculation of start tractive power in bridge swing |
| 摘要 |
| 結(jié)合濱德高速公路上跨京滬鐵路立交橋轉(zhuǎn)體施工項(xiàng)目，從試驗(yàn)原理入手，剖析了轉(zhuǎn)體稱重試驗(yàn)常規(guī)做法的不足之處，并探討了考慮實(shí)際支承情況的啟動牽引力計(jì)算方法。研究結(jié)果認(rèn)為：梁端壓重代替千斤頂頂升，能保證結(jié)構(gòu)安全，且更接近球面轉(zhuǎn)動的理想狀況；稱重試驗(yàn)測試轉(zhuǎn)體水平位移 |
