| 路涵過渡段涵洞豎向壓力現(xiàn)場(chǎng)試驗(yàn)研究(51 卷) |
| 英文標(biāo)題 |
| In situ test study on vertical pressure of culvert at road-culvert transition zone |
| 摘要 |
| 路堤填方作用下涵洞豎向壓力與路堤填土高度和涵洞寬度之比H/D有直接關(guān)系。針對(duì)涵頂路基填方作用于上埋式剛性涵洞的土壓力問題，在兩個(gè)不同填土高度(5 m、3 m)的涵洞頂和過渡段路基內(nèi)埋設(shè)土壓力傳感器，測(cè)試分析涵洞和過渡段路基的豎向壓力在填筑過程中的變化特性。本工點(diǎn)試驗(yàn) |
