| 標(biāo)題 |
| 水泥攪拌樁復(fù)合地基樁土應(yīng)力比的現(xiàn)場(chǎng)試驗(yàn)分析(50 卷) |
| 英文標(biāo)題 |
| In site test analysis on stress ratio of pile to soil in composite foundation with cement mixing piles |
| 摘要 |
| 樁土應(yīng)力比是攪拌樁復(fù)合地基設(shè)計(jì)、施工時(shí)的重要控制參數(shù)。根據(jù)公路路基現(xiàn)場(chǎng)試驗(yàn)的實(shí)測(cè)數(shù)據(jù)，分析帶格柵褥墊層不同位置處攪拌樁樁頂及樁間土的應(yīng)力變化、樁頂和樁間土的沉降規(guī)律，總結(jié)了路堤施工過程荷載的傳遞規(guī)律，對(duì)水泥攪拌樁復(fù)合地基的設(shè)計(jì)和施工提出了具體建議。 |
