UNIVERSITY OF TRANSPORT AND COMMUNICATIONS INTERNATIONAL EDUCATION FACULTY ---------------- GRADUATION THESIS Supervisor : Assoc. Do Anh Tu Examiner : Student : Class : R&B Engineering K58 DONG QUANG PHUC R&B ENGINEERING K58 Ha Noi – 2022 2 DONG QUANG PHUC R&B ENGINEERING K58 PREFACE In the era of country development, we need to build more and more structures to serve the demand of human life. In which, Transportation is one of the most important fields that considered with large investment and concern of society. We need to get much more skillful engineers to update modern technologies of the world and build for us many modern structures with high quality and aesthetic.
Transportation is one of the most important sectors that contribute to the development of a nation. Constructing structures such as bridges, tunnel, or highway helps to connect all the areas, improves the development of socio-eco, politics, and defense. The future of transportation sector is not only the increasing of transport systems, transportation infrastructure… but also the education for new engineer generation. By take into account in education for future generation, we will have a sustainable development in human resource.
That is the first condition for the development of transportation sector in the future. After 5 year learnt in the University of Transport and Communications, with the willing of myself and the whole-heart teaching of my teachers, I have been grant many experiences with help me in the future. This graduation project is the result of 5 years studied in this University. It is the summary of my studying process.
My special thanks to my supervisor Assoc. Do Anh Tu and also to PhD. Nguyen Van Hau, who helped me a lot to finish my graduation thesis. During the process to finish my graduation project, because of the time and my limited knowledge, so there will be some mistakes.
I hope I can get the advice of our lecturers to make my graduation project finished. Thank you for all Hanoi, June 2022 1 DONG QUANG PHUC R&B ENGINEERING K58 Dong Quang Phuc COMMENT OF SUPERVISOR 1. EVALUATION OF CONTENT AND QUALITY OF REPORT:. EVALUATION OF WORKING ATTITUDE OF STUDENT:.

History Among many construction technologies of reinforced concrete bridges, cantilever construction technology emerges with many advantages and has been widely applied all over the world as well as in Vietnam. Since 1977 cantilever and cantilever methods have been used. applied to construct a number of bridges in Vietnam such as: Rao, Niem, An Duong bridges in Hai Phong (cantilevered), T-beam-frame bridges worn according to the multi-span static scheme at Binh bridge construction site in Quang Ninh, Nong Tien Bridge in Tuyen Quang, Phu Luong Bridge on National Highway 5, recently Bar Tri Bridge and Vinh Tuy Bridge crossing the Red River in Hanoi, etc.
