ree of paction。軟基處理。壓實度。軟基處理有:砂墊層,置換填土,拋石擠淤法,加固土樁法,擠密砂樁,反壓護(hù)道法,塑料排水板法。該項目路基大致分為一般路基(良好路基)和特殊路基(軟土路基)。一條公路的建設(shè)是否能達(dá)到預(yù)期的建設(shè)目的,主要是取決于路基施工情況,而在路基施工當(dāng)中施工質(zhì)量無疑是其中核心。而路基作為道路結(jié)構(gòu)的重要組成部分,它既是道路的主體,又是路面的載體與基礎(chǔ),路基的質(zhì)量直接決定著道路的質(zhì)量。 畢 業(yè) 設(shè) 計題目: 太湖金港市政工程路基施工質(zhì)量控制 院 系: 路橋與港航工程學(xué)院 專業(yè)名稱: 港口與航道工程技術(shù) 班 級: 122092 學(xué)號: 12209236 姓 名: 李大杰 指導(dǎo)教師: 高奇浪 完成時間: 2015 年 5 月 15 日 摘要:隨著國家經(jīng)濟(jì)的迅猛增長,城市化日益加快。對于交通的需求也愈加提升,如何提高城市道路的施工質(zhì)量,已成為當(dāng)務(wù)之急。嚴(yán)格控制路基的施工,保證路基施工的質(zhì)量,對提高道路建設(shè)質(zhì)量起著重要作用。結(jié)合該項目的實際情況,本論文主要探討路基工程質(zhì)量以及對施工的控制。影響一般路基質(zhì)量的有:整體穩(wěn)定性,強(qiáng)度,水溫穩(wěn)定性,排水設(shè)施等多種因素。關(guān)鍵詞:路基。粒徑級配。灌砂法Abstract:With the rapid growth of national economy, the quickening of urbanization. For the traffic demand is increasingly, how to improve the quality of urban road construction, has bee the top priority. As an important part of road structure and roadbed, it is not only the body of the road, it is the carrier of pavement and foundation, the quality of the subgrade directly determines the quality of the road. Strict control of roadbed construction, guarantee the quality of roadbed construction, to improve the quality of road construction plays an important role. A highway construction can achieve the desired purpose, subgrade construction mainly depends on the situation, and in the construction quality of subgrade construction is the core. In bination with the practical situation of the project, this thesis mainly discusses the subgrade construction quality as well as to the construction of the control. The project roadbed subgrade bed of (good) roughly divided into general and special subgrade (soft soil subgrade). Affecting the quality of general subgrade are: the overall stability, strength, water stability, drainage facilities and other factors. Soft foundation treatment are: sand cushion layer, filling replacement, riprap crowded silting method, method of reinforcing soil pile, sand paction pile, back pressure to protect road, plastic drainage plate method.Keywords: subgrade 。 particle size distribution 。 sand filling method 目錄 1 1 1 1 1 2 3 3 3 3 3 3 4 4 4 5 5 5 6 6 6 6 7 7 7 7 7 8 8 8 9 9 10(最大干密度)和最佳含水量的確定方法 10 11 11 11 12 12 ………………………………………………………………………….12 …………………………………………………………….....12 ………………………………………………………………………….12結(jié)論 15參考文獻(xiàn) 16致謝 17 一般路基是指修筑在良好的地質(zhì)、水文、氣候條件下的路基。但高填方路堤,深挖方路塹須進(jìn)行個別論證和驗算。特殊路基主要有: (1)濕黏土路基、軟土地區(qū)路基、紅黏土地區(qū)路基、膨脹土地區(qū)路基、黃土地區(qū)路 基、鹽漬土地區(qū)路基、風(fēng)積沙及沙漠地區(qū)路基; (2)季節(jié)性凍土地區(qū)路基、多年凍土地區(qū)路基、涎流冰地區(qū)、雪害地區(qū)路基; (3)滑坡地段路基、崩塌與巖堆地段路基、泥石流地區(qū)路基; (4)巖溶地區(qū)路基、采空區(qū)路基;
