【摘要】：近二十年對橋墩柱性能的研究一直是一個熱點問題�，F(xiàn)有的大量已建城市橋梁由于早期設(shè)計規(guī)范不合理、結(jié)構(gòu)使用功能改變、施工缺陷以及長期使用過程中的損傷、老化造成抗震性能不良、承載力不足等諸多影響其安全和使用功能的問題非常普遍，繼續(xù)使用就必須采用切實有效的加固改造方法進行加固。通過維修加固城市橋梁，可以預(yù)防和避免城市橋梁的坍塌造成經(jīng)濟損失和人員的傷亡，，城市橋梁維修加固后，不但可以延長現(xiàn)有城市橋梁的使用壽命，用盡量少的資金投入，恢復(fù)城市橋梁的通行要求，還可以延緩城市橋梁建設(shè)投資的集中性，為國家?guī)砭薮蟮慕?jīng)濟效益和社會效益。 本文對現(xiàn)有各種方法進行了簡單介紹，結(jié)合華南路三期永泰立交主跨T構(gòu)墩柱加固工程，對集中常用的加固方法進行了比選，綜合運用了多項加固技術(shù)，在實施過程中，對加固過程中技術(shù)、質(zhì)量、安全、文明、環(huán)保、進度等措施進行了詳細介紹。 舊橋的加固工程是一項繁雜的專業(yè)、系統(tǒng)工程，急需制定相應(yīng)的城市橋梁加固的規(guī)范，而且應(yīng)成立專業(yè)的維修加固公司，專門從事城市舊橋維修加固工程的管理、設(shè)計和施工。隨著各種新型材料的發(fā)展，新施工工藝和新材料的運用，使得橋梁的維修加固對象更廣泛，施工更加方便快速。通過華南路三期永泰立交主跨T構(gòu)墩柱加固工程的實施，解決了工程中遇到的實際難題，并且經(jīng)濟效益和社會效益可觀，具有較大的推廣價值。
[Abstract]:Study on the performance of piers for nearly twenty years has been a hot issue. A large number of existing bridges have been built in the city since the early design is not reasonable, change the structure of the use function, construction defects and long-term use in the process of injury caused by aging, seismic performance is bad, lack of capacity and many other effects on the safety and use function. Very common, continue to use must adopt the effective reinforcement method for reinforcement. Through the maintenance and reinforcement of Bridge City, can prevent and avoid the city bridge collapse caused economic losses and personnel casualties, city bridge maintenance and reinforcement, it can not only prolong the service life of the bridge the existing city, with less capital investment, access for the restoration of city bridge, concentration could also slow the city bridge construction investment, bring huge economic benefits and social benefits for the country.
The existing various methods were introduced, combined with the Southern China road three Yongtai overpass T main span pier column reinforcement project, focus on the common reinforcement method were compared and selected, with many reinforcement technology, in the implementation process, the process of strengthening technology, quality, safety, environmental protection, the progress of civilization. Such measures are introduced in detail.
The old bridge reinforcement project is a complicated system engineering, professional, need to develop appropriate city bridge strengthening norms, and should set up a professional repair company, specializing in city bridge maintenance and strengthening project management, design and construction. With the development of a variety of new materials, the use of new construction technology and new materials so, the bridge maintenance and reinforcement of the object is more extensive, more convenient and fast construction. By three Southern China road Yongtai overpass T main span pier column reinforcement project implementation, to solve the practical problems encountered in engineering, and has considerable economic benefit and social benefit, has great popularization value.
