前言此次畢業設計是為了應用型本科人才的培養需要,是對應用型本科人才對所學知識的一個檢驗。本設計根據橋梁的地理環境和周圍的環境狀況,以及對于經濟方面的要求,最終選定的橋型為預應力連續梁橋。通過在預制場預制主梁,在橋位定位安裝。35312
預應力混凝土連續梁橋以結構受力性能好、變形小、行車平順舒適、造型簡潔美觀、養護費用少、抗震能力強等。預應力混凝土橋仍是最富有競爭力的主要橋型之一。我國的預應力混凝土結構起步雖然比較晚,但是由于隨著我國綜合國力的發展,近年來得到了飛速發展。現在,我國已然成為了世界上的橋梁大國,這也是我國的綜合實力的體現。預應力混凝土橋主要是受彎構件,即要承受足夠的彎矩,又要充分節省材料節省造價。
雖然預應力混凝土橋梁的發展還不到80年。但是,在橋梁結構中,隨著預應力理論的不斷成熟和實踐的不斷發展,預應力混凝土橋梁結構的運用必將越來越廣泛。
preface The graduation design is for the cultivation of applied undergraduate talents need, is the applied undergraduate talents with knowledge in a test.
    This design according to the geographical environment of the bridge and the surrounding environment, as well as to the requirement of the economy, eventually selected bridge for prestressed concrete continuous girder bridge. Through the prefabricated precast girder, installed in the bridge location.
Prestressed concrete continuous girder bridge with structure stress performance good, small deformation, driving smooth and comfortable, beautiful modelling concise, less maintenance costs, the seismic ability, etc. Prestressed concrete bridge is still the most competitive one of the main bridge.Although of prestressed concrete structures in China started relatively late, but as with the development of China's comprehensive national strength, obtained the rapid development in recent years. Now, our country has become the power of the bridge in the world, this also is the embodiment of the comprehensive strength of ourcountry.Prestressed concrete bridge is primarily a flexural member, that is, to the bending moment, enough to fully save material to save cost.                源¥自%六:維;論-文'網=www.aftnzs.live
Although the development of prestressed concrete bridge is less than 80. But, in the bridge structure, with the mature of the theory of prestressed and practice of development, the use of prestressed concrete bridge structure will be more and more widely.
