39、p>　　對土木工程的發(fā)展起關鍵作用的，首先是作為工程物質基礎的土木建筑材料，其次是隨之發(fā)展起來的設計理論和施工技術。每當出現(xiàn)新的優(yōu)良的建筑材料時，土木工程就 會有飛躍式的發(fā)展。 </p><p>　　人們在早期只能依靠泥土、木料及其它天然材料從事營造活動，后來出現(xiàn)了磚和瓦這種人工建筑材料，使人類第一次沖破了天然建筑材料的束縛。中國在公元前十一世紀 的西周初期制造出瓦。最早的磚出現(xiàn)在公元前五世紀至公元前三世紀

40、戰(zhàn)國時的墓室中。磚和瓦具有比土更優(yōu)越的力學性能，可以就地取材，而又易于加工制作。 </p><p>　　磚和瓦的出現(xiàn)使人們開始廣泛地、大量地修建房屋和城防工程等。由此土木工程技術得到了飛速的發(fā)展。直至18～19世紀，在長達兩千多年時間里，磚和瓦一直是土木工程的重要建筑材料，為人類文明作出了偉大的貢獻，甚至在目前還被廣泛采用。 </p><p>　　鋼材的大量應用是土木工程的第二次飛躍。 十

41、七世紀70年代開始使用生鐵、十九世紀初開始使用熟鐵建造橋梁和房屋，這是鋼結構出現(xiàn)的前奏。 </p><p>　　從十九世紀中葉開始，冶金業(yè)冶煉并軋制出抗拉和抗壓強度都很高、延性好、質量均勻的建筑鋼材，隨后又生產出高強度鋼絲、鋼索 。于是適應發(fā)展需要的鋼結構得到蓬勃發(fā)展。除應用原有的粱、拱結構外，新興的桁架、框架、網架結構、懸索結構逐漸推廣，出現(xiàn)了結構形式百花爭艷的局面。 </p><p>

42、　　建筑物跨徑從磚結構、石結構、木結構的幾米、幾十米發(fā)展到鋼結構的百米、幾百米，直到現(xiàn)代的千米以上。于是在大江、海峽上架起大橋，在地面上建造起摩天大樓和高聳鐵塔，甚至在地面下鋪設鐵路，創(chuàng)造出前所未有的奇跡。 </p><p>　　為適應鋼結構工程發(fā)展的需要，在牛頓力學的基礎上，材料力學、結構力學、工程結構設計理論等就應運而生。施工機械、施工技術和施工組織設計的理論也隨之發(fā)展，土木工程從經驗上升成為科學，在工程實踐

43、和基礎理論方面都面貌一新，從而促成了土木工程更迅速的發(fā)展。 </p><p>　　十九世紀20年代，波特蘭水泥制成后，混凝土問世了。混凝土骨料可以就地取材，混凝土構件易于成型，但混凝土的抗拉強度很小，用途受到限制。 十九世紀中葉以后，鋼鐵產量激增，隨之出現(xiàn)了鋼筋混凝土這種新型的復合建筑材料，其中鋼筋承擔拉力，混凝土承擔壓力，發(fā)揮了各自的優(yōu)點。 二十世紀初以來，鋼筋混凝土廣泛應用于土木工程的各個領域。 </p

44、><p>　　從三十年代開始，出現(xiàn)了預應力混凝土。預應力混凝土結構的抗裂性能、剛度和承載能力，大大高于鋼筋混凝土結構，因而用途更為廣闊。土木工程進入了鋼筋混凝土和預應力混凝土占統(tǒng)治地位的歷史時期?；炷恋某霈F(xiàn)給建筑物帶來了新的經濟、美觀的工程結構形式，使土木工程產生了新的施工技術和工程結構設計理論。這是土木工程的又一次飛躍發(fā)展。 </p><p>　　建造一項工程設施一般要經過勘察、設計和施工

45、三個階段，需要運用工程地質勘察、水文地質勘察、工程測量、土力學、工程力學、工程設計、建筑材料、建筑設備、工程機械、建筑經濟等學科和施工技術、施工組織等領域的知識 ，以及電子計算機和力學測試等技術。因而土木工程是一門范圍廣闊的綜合性學科。隨著科學技術的進步和工程實踐的發(fā)展，土木工程這個學科也已發(fā)展成為內涵廣泛、門類眾多、結構復雜的綜合體系。 </p><p>　　土木工程是伴隨著人類社會的發(fā)展而發(fā)展起來的。它所建造

46、的工程設施反映出各個歷史時期社會經濟、文化、科學、技術發(fā)展的面貌，因而土木工程也就成為社會歷史發(fā)展的見證之一。 </p><p>　　遠古時代，人們就開始修筑簡陋的房舍、道路、橋梁和溝澶，以滿足簡單的生活和生產需要。后來，人們?yōu)榱诉m應戰(zhàn)爭、生產和生活以及宗教傳播的需要，興建了城池、運河、宮殿、寺廟以及其他各種建筑物。 </p><p>　　許多著名的工程設施顯示出人類在這個歷史時期的創(chuàng)造力

47、。例如，中國的長城、都江堰、大運河、趙州橋、應縣木塔，埃及的金字塔，希臘的巴臺農神廟，羅馬的給水工程、科洛西姆圓形競技場(羅馬大斗獸場)，以及其他許多著名的教堂、宮殿等。 </p><p>　　產業(yè)革命以后，特別是到了20世紀，一方面社會向土木工程提出了新的需求；另一方面，社會各個領域為土木工程的前進創(chuàng)造了良好的條件。因而這個時期的土木工程得到突飛猛進的發(fā)展。在世界各地出現(xiàn)了現(xiàn)代化規(guī)模宏大的工業(yè)廠房、摩天大廈，核

48、電站、高速公路和鐵路、大跨橋梁、大直徑運輸管道長隧道、大運河、大堤壩、大飛機場、大海港以及海洋工程等等?，F(xiàn)代土木工程不斷地為人類社會創(chuàng)造嶄新的物質環(huán)境，成為人類社會現(xiàn)代文明的重要組成部分。 </p><p>　　土木工程是具有很強的實踐性的學科。在早期，土木工程是通過工程實踐，總結成功的經驗，尤其是吸取失敗的教訓發(fā)展起來的。從17世紀開始，以伽利略和牛頓為先導的近代力學同土木工程實踐結合起來，逐漸形成材料力學、結

49、構力學、流體力學、巖體力學，作為土木工程的基礎理論的學科。這樣土木工程才逐漸從經驗發(fā)展成為科學。 </p><p>　　在土木工程的發(fā)展過程中，工程實踐經驗常先行于理論，工程事故常顯示出未能預見的新因素，觸發(fā)新理論的研究和發(fā)展。至今不少工程問題的處理，在很大程度上仍然依靠實踐經驗。 </p><p>　　土木工程技術的發(fā)展之所以主要憑借工程實踐而不是憑借科學試驗和理論研究，有兩個原因：一是

50、有些客觀情況過于復雜，難以如實地進行室內實驗或現(xiàn)場測試和理論分析。例如，地基基礎、隧道及地下工程的受力和變形的狀態(tài)及其隨時間的變化，至今還需要參考工程經驗進行分析判斷。二是只有進行新的工程實踐，才能揭示新的問題。例如，建造了高層建筑、高聳塔桅和大跨橋梁等，工程的抗風和抗震問題突出了，才能發(fā)展出這方面的新理論和技術。 </p><p>　　在土木工程的長期實踐中，人們不僅對房屋建筑藝術給予很大注意，取得了卓越的成就
