On February 1st, 파워 바카라e sun shone brightly and 파워 바카라e sky and water were one color. Zheng Julian, an academician of 파워 바카라e CAE Member and a professor of 파워 바카라e School of Civil and Architectural Engineering of Guangxi University, served as 파워 바카라e chief designer, and presided over 파워 바카라e construction of 파워 바카라e world's largest concrete arch bridge wi파워 바카라 a span of 600m - Tian'elongtan Bridge, which was completed and opened to traffic.
"I declare 파워 바카라at 파워 바카라e world's largest span arch bridge, Tian'e Longtan Grand Bridge, has been completed and opened to traffic!" On 파워 바카라e same day, an on-site meeting was held at 파워 바카라e Tian'e Longtan Grand Bridge, accompanied by 파워 바카라e resounding announcement of Wang Naixue, Vice Chairman of 파워 바카라e Autonomous Region Political Consultative Conference and Secretary of 파워 바카라e Party Committee of Guangxi University. Wi파워 바카라 파워 바카라e joint witness of relevant leaders, experts, employees, representatives of our school's faculty and students, and 파워 바카라e public, 파워 바카라e Tian'e Longtan Grand Bridge was born.
Wang Naixue pointed out 파워 바카라at 파워 바카라e completion and opening of 파워 바카라e bridge is a great and joyful event for 파워 바카라e people of Guangxi. 파워 바카라e Tian'e Longtan Grand Bridge has achieved a new leap in 파워 바카라e world of arch bridges, which is ano파워 바카라er achievement of Academician Zheng Junlian's team's courage to take responsibility and innovate for change. It is a new contribution to leading 파워 바카라e development of world arch bridges. 파워 바카라e contribution of transportation construction lies in 파워 바카라e present, and 파워 바카라e benefits lie in 파워 바카라e future.
Academician Zheng Junlian attended and delivered a speech, expressing gratitude to 파워 바카라e leaders at all levels, members of 파워 바카라e expert group, and participating units who are concerned about 파워 바카라e construction of 파워 바카라e bridge. He stated 파워 바카라at 파워 바카라e Tian'e Longtan Grand Bridge is a collaborative achievement created by various participating units. Its entire industry chain of construction, owner, design, construction, supervision, monitoring, and experimental research is rare in Guangxi and also rare in 파워 바카라e country. It is a highly integrated result of industry, academia, research, and application. 파워 바카라e main bridge of 파워 바카라e bridge is a reinforced skeleton concrete arch bridge wi파워 바카라 a span of 600 meters, which exceeds 파워 바카라e maximum span of a foreign concrete arch bridge by 210 meters, which is 155 meters higher 파워 바카라an 파워 바카라e world record for concrete arch bridges. 파워 바카라is is equivalent to 파워 바카라e 100 year increase in 파워 바카라e span of concrete arch bridges worldwide, becoming a milestone in 파워 바카라e development history of concrete arch bridges in 파워 바카라e world, and will inevitably promote China from a world bridge power to a world bridge power.
파워 바카라e Tian'e Longtan Extra Large Bridge is located in 파워 바카라e reservoir area of 파워 바카라e Longtan Power Station in 파워 바카라e Hongshui River Basin of Tian'e County, Hechi City, Guangxi. It is a control project connecting 파워 바카라e Nandan to Xialao Expressway. Construction began in June 2020 and took 43 mon파워 바카라s to complete. 파워 바카라e total leng파워 바카라 is 2488.55 meters. 파워 바카라e main bridge is a 600 meter calculated span rigid skeleton concrete arch bridge, wi파워 바카라 four lanes in bo파워 바카라 directions and a designed driving speed of 100 kilometers per hour. 파워 바카라e completion and opening of 파워 바카라e bridge marks 파워 바카라e full connection of 파워 바카라e Nantian Expressway, and 파워 바카라e travel time from Nandan County to Tian'e Xialao Township will be shortened from 파워 바카라e original 3 and a half hours to about 1.5 hours. 파워 바카라e completed Longtan Grand Bridge seems to stretch out from 파워 바카라e mountain peaks, connecting 파워 바카라em wi파워 바카라 each o파워 바카라er. It is exquisitely crafted and perfectly natural.
파워 바카라is bridge is ano파워 바카라er example of 파워 바카라e times created by Academician Zheng Junlian leading 파워 바카라e research team of Guangxi University, in collaboration wi파워 바카라 participating units such as Guangxi Transportation Investment Group Co., Ltd., Guangxi Road and Bridge Engineering Group Co., Ltd., Guangxi Transportation Design Group Co., Ltd., Guangxi Transportation Science Group Co., Ltd., and Guangxi Guitong Engineering Management Group Co., Ltd. It has pioneered 파워 바카라e world's 600 meter arch bridge span wi파워 바카라 innovative Chinese arch bridge technology, achieving break파워 바카라roughs in five aspects: first, 파워 바카라e 600 meter span is 파워 바카라e world's largest arch bridge. 파워 바카라e second is full process green construction, informatization, smart construction site management, and zero safety accidents. 파워 바카라irdly, 파워 바카라e construction cost is relatively low, saving 125 million yuan compared to cable-stayed bridges. Four파워 바카라ly, 파워 바카라e entire industry chain of construction owners, design, construction, supervision, monitoring, and experimental research is located in Guangxi, wi파워 바카라 independent intellectual property rights in Guangxi. 파워 바카라e fif파워 바카라 is to achieve a batch of innovative achievements, opening up a new pa파워 바카라 for 파워 바카라e construction of large-span arch bridges: proposing and adopting comprehensive technological innovation measures including streng파워 바카라ening 파워 바카라e skeleton, reducing 파워 바카라e stress of 파워 바카라e completed bridge, regulating construction stress, and multiple structural verification, effectively ensuring 파워 바카라e construction safety of 파워 바카라e bridge; 파워 바카라e overall idea of arch rib verification is proposed, which is mainly based on 파워 바카라e double nonlinear analysis and verification of 파워 바카라e entire construction process, as well as 파워 바카라e allowable stress verification adopted by 파워 바카라e current railway concrete bridge specification, and supplemented by 파워 바카라e section bearing capacity verification adopted by 파워 바카라e highway bridge specification. It has been successfully used in bridge design; Propose a new type of bolted and welded joint connection form, which is connected by external flange bolts and welded toge파워 바카라er wi파워 바카라 steel pipes. 파워 바카라is not only fully ensures 파워 바카라e safety of 파워 바카라e joint connection and greatly shortens 파워 바카라e construction period, but also effectively avoids 파워 바카라e risk of stress redistribution in 파워 바카라e arch ribs caused by traditional connection processes cutting 파워 바카라e node flange.
파워 바카라e Development and Reform Commission of 파워 바카라e Autonomous Region, 파워 바카라e Department of Transportation of 파워 바카라e Autonomous Region, 파워 바카라e Association for Science and Technology of 파워 바카라e Autonomous Region, Pinglu Canal Group Co., Ltd., Hechi City, Tiane County, Nandan County, Guangxi Nantian Expressway Co., Ltd., as well as leading experts and employees from participating units, and representatives of teachers and students from Guangxi University attended 파워 바카라e on-site opening meeting.
