畢 業(yè) 論 文 論文題目: 淺析世紀大道軟基處理的方法 系 部: 路 橋 工 程 系 專業(yè)名稱: 高等級公路維護與管理 南京交通職業(yè)技術(shù)學(xué)院畢業(yè)論文 淺析世紀大道軟基處理的方法 【摘要】 本論文在綜合分析工程地質(zhì)情況和工程造價等因素的基礎(chǔ)上,通過分析比較軟基處理的施工工藝和適應(yīng)軟基的范圍,最終選用 CFG 樁來處理本段道路軟土地基。根據(jù)現(xiàn)場實際施工效果來看,使用 CFG 樁這種方法處理本路段上的軟基,完全可以達到設(shè)計強度和 質(zhì)量的要求。本論文敘述從施工準備到最終軟基處理檢測合格的各個環(huán)節(jié),充分表明采用 CFG 樁在該路段軟基處理中的優(yōu)越性。 關(guān)鍵詞: CFG樁 ;軟土地基;危害;工程質(zhì)量;壓實度 On Century Boulevard soft ground treatment methods Abstract : The paper on the basis of prehensive analysis of engineering geology and engineering cost and other factors, by analyzing and paring the construction of several other soft ground treatment process and to meet the range of soft ground, the final selection the CFG pile to deal with this section of the road soft ground. According to the actual construction results using this method of CFG pile on the road soft ground, can achieve the design strength and quality requirements. This paper describes the construction preparation to final soft ground treatment tested and fully demonstrates the superiority of CFG pile in soft ground treatment of the road. Keywords : CFG pile; soft ground; hazards; the quality of the project。degree of paction 南京交通職業(yè)技術(shù)學(xué)院畢業(yè)論文 目 錄 前 言 ??????????????????????????????????? 1 ????????????????????????????? 1 ?????????????????????? ??????? 1 剪切拉裂 ?????????????????????????????? 1 浸水沉陷 ?????????????????????????????? 1 ???????????????????????????? 1 該路段軟基土層分布 ????????????????????????? 2 設(shè)計勘察院處理意見 ????????????????????????? 3 處理軟土地基的工程實 ???????????????????????? 3 施工準備情況 ???????????????????????????? 4 樁位放線 ??????????????????????????????? 5 樁基就位調(diào)平 ????????????????????????????? 5 鉆孔至設(shè)計標高 ??????????????????????????? 5 泵送混合料 ?????????????????????????????? 5 拔管 ?????????????????????????????? ??? 6 轉(zhuǎn)機 ????????????????????????????????? 6 清理樁間土 ? ?????????? ????????????????? 6 澆筑樁帽和鋪設(shè)褥墊層 ?? ?????????????????????? 7 樁質(zhì)量檢測項目 ??????????????????????????? 7 ???????????????????????????? 7 樁施工中的問題原因分析與防止措施 ????????????????? 9 樁頭變形 ??????????????????????????????? 9 樁頭空芯 ??????????????????????????????? 9 縮徑 ????????????????????????????????? 9 擴徑 ????????????????????????????????? 10 離析 ????????????????????????????????? 10 斷樁 ????????????????????????????????? 10 ???????????????????????? 10 南京交通職業(yè)技術(shù)學(xué)院畢業(yè)論文 ??????????? ??????????????????????? 11 致謝 ???????????????????????????????????? 13 參考
