style="text-indent:25px">纜索懸吊法懸索橋的施工,通常是先架設(shè)纜索,用纜索上臨時加設(shè)的走行吊架，將加勁梁的梁段逐漸提升，懸掛在纜索垂下的吊桿上，調(diào)整位置后拼裝成整跨的加勁梁。施工時加勁梁梁段的自重，由纜索承受。美國的金門、韋拉扎諾海峽及英國的亨伯等不錯的懸索橋（見彩圖），均用這種方法施工。瑞典阿斯克勒峽灣(Asker Fjord)鋼管拱橋（1960年）,利用同一原理提升跨度278米的管拱節(jié)段，懸吊在臨時施工的纜索下，調(diào)整位置后拼鉚成拱，整體降落到支座上。拱、梁組合結(jié)構(gòu)，也可采用此法安裝架設(shè),如日本天草二號橋（1966年）的156.8米朗格爾桁架梁，就是這樣施工的。</p><p style="text-indent:25px">在進(jìn)行結(jié)構(gòu)設(shè)計的過程中，首先是選擇經(jīng)濟(jì)合理的結(jié)構(gòu)方案，其次是結(jié)構(gòu)分析設(shè)計，當(dāng)然，規(guī)范制定了安全系數(shù)和指標(biāo)以確保結(jié)構(gòu)的安全性。按照程序或公式進(jìn)行計算即可。因此就在這個環(huán)節(jié)上忽視了對現(xiàn)階段的施工和管理水平、材料耐久性、結(jié)構(gòu)的后期改造、加寬、維護(hù)以及施工過程中可能造成的人為失誤等問題的充分考慮。即沒有采用適當(dāng)?shù)陌踩?、缺乏?xì)部結(jié)構(gòu)設(shè)計等主動型的設(shè)計方法來確保橋梁使用性能的充分體現(xiàn)。因此，不少橋梁、雖然滿足了現(xiàn)有設(shè)計規(guī)范的強(qiáng)度要求，但不出幾年就因為耐久性出了較大小小的問題，嚴(yán)重下去必然會影響到結(jié)構(gòu)安全。為解決這一問題，在設(shè)計和建造階段要挑戰(zhàn)傳統(tǒng)設(shè)計理念：對結(jié)構(gòu)設(shè)計時應(yīng)使結(jié)構(gòu)具有六大特性，即可檢性、可修性、可換性、可強(qiáng)性、可控性及可持續(xù)性。充分認(rèn)識到結(jié)構(gòu)在設(shè)計壽命期內(nèi)各個組成部件具有不同的耐久性極限，需要經(jīng)常維修，甚至更換或加固，才能保證結(jié)構(gòu)在設(shè)計壽命期內(nèi)的服務(wù)功能。南京三橋、蘇通大橋、昂船洲大橋的建造，表明在大跨徑鋼橋的優(yōu)勢越來越明顯。</p><div

style="text-indent:25px">鋼橋與鋼混凝土橋的不同之處：雖然鋼橋的強(qiáng)度大，但它抗腐蝕性較弱，所以不僅要細(xì)心選材，還需要經(jīng)常檢查和維修，費用較高。與鋼筋混凝土橋相比，鋼橋能降低自身梁高和減少自身重量=我們熟悉的武漢長江大橋、南京長江大橋、杭州灣大橋都是鋼橋。鋼筋混凝土橋形成于19世紀(jì)后半葉，雖然鋼筋混凝土橋出現(xiàn)較晚，但自出現(xiàn)以來不到200年時間就已經(jīng)被普遍建設(shè)，鋼筋混凝土橋的發(fā)展速度之快有目共睹。鋼筋混凝土橋的主要材料——鋼筋混凝土并非從一開始就被作為橋梁的重要建材使用，它初常用于修建水壩、管道和樓板，直至1875年，法國園藝師才主持建成了一座鋼筋混凝土橋，可惜的是該橋早已不存在了。假如需要架建中小型跨度的橋梁，鋼筋混凝土橋是不錯選擇。假如需要架建跨度較大的橋梁，則選擇鋼橋更合適。鋼橋發(fā)展取得了驕人的成績，南京三橋、蘇通大橋、昂船洲大橋的建造，表明在大跨徑鋼橋的優(yōu)勢越來越明顯。深圳鋼橋繪圖軟件公司哪家好</p><p
