| Study and application of gravity mortar-grouting in formation of bridge’s bearing on high-speed railway |
| 摘要 |
| 橋梁鋪架質(zhì)量是保證梁體受力均勻的重要環(huán)節(jié)。國內(nèi)梁體架設(shè)已逐步采用測力千斤頂作為臨時(shí)支點(diǎn)，在支承墊石與支座底面之間采用自流平砂漿材料灌入填實(shí)后再落梁就位的施工工藝。本文結(jié)合高速鐵路工程，對影響自流平砂漿性能的因素進(jìn)行了試驗(yàn)分析，研制出施工性能好，早期強(qiáng)度高 |
