| 標(biāo)題 |
| 軟土地基硬殼層對(duì)路堤工程特性影響的研究(50 卷) |
| 英文標(biāo)題 |
| Study about influence of stiff-shell-layer of soft subsoil on subgrade’s engineering performance |
| 摘要 |
| 對(duì)于修建在軟土地基硬殼層上的路堤，經(jīng)過(guò)硬殼層的應(yīng)力擴(kuò)散后，施加到軟土層頂面的附加應(yīng)力會(huì)大大減小。采用非線性有限元數(shù)值計(jì)算方法，研究了路堤荷載作用下硬殼層剛度、路堤高度以及軟基厚度對(duì)硬殼層軟土地基變形特征，以及硬殼層應(yīng)力擴(kuò)散效果的影響。 |
