| 高速鐵路無砟道岔用道岔板設(shè)計(jì)研究(51 卷) |
| 英文標(biāo)題 |
| Design study on turnout slab of ballastless track turnout on high speed railway |
| 摘要 |
| 結(jié)合國產(chǎn)高速客運(yùn)專線道岔的具體情況，首次提出國產(chǎn)化客專道岔板的設(shè)計(jì)方案。采用梁—板—板有限元計(jì)算模型對(duì)我國高速客運(yùn)專線42號(hào)聯(lián)絡(luò)線道岔板進(jìn)行力學(xué)計(jì)算，分析了道岔板結(jié)構(gòu)在運(yùn)營、運(yùn)輸、施工以及在溫度荷載作用下的受力狀態(tài)，并對(duì)道岔板的承載能力以及裂縫控制水平進(jìn)行 |
