| 采動(dòng)區(qū)框架橋抗變形優(yōu)化研究(52卷) |
| 英文標(biāo)題 |
| Optimum study on anti-deformation of framed bridge in mining subsidence area |
| 摘要 |
| 根據(jù)采動(dòng)區(qū)地表沉陷變形規(guī)律和框架橋結(jié)構(gòu)特征,建立了合理的數(shù)值計(jì)算模型,研究了地下開采引起的地表移動(dòng)變形對原橋體結(jié)構(gòu)和優(yōu)化結(jié)構(gòu)產(chǎn)生的附加內(nèi)力的變化規(guī)律,以及基底附加應(yīng)力變化和位移變化規(guī)律。本項(xiàng)研究為采動(dòng)區(qū)建筑物的優(yōu)化設(shè)計(jì)提供了依據(jù)。 |
