“…Although the technology reduces both environmental impact and traffic disruption, the use of expensive temporary structures (lots of stayed cables and heightened segments of the pylon) increases onsite construction cost and time.

“…Self-anchored suspension bridges have found increasingly wide applications in urban bridge engineering as a landmark, due to its attractive architectural appearance and lightweight configuration [11][12][13]. Due to being anchored to the girder, the main cables could not be erected until the girder has been built on lots of temporary supports, which inevitably causes serious impacts on environment and traffic.…”

“…Due to being anchored to the girder, the main cables could not be erected until the girder has been built on lots of temporary supports, which inevitably causes serious impacts on environment and traffic. This issue has emerged during the erection of several typical self-anchored suspension bridges, such as the Yongjong Bridge in Korea [13], San Francisco-Oakland Bay Bridge in the States [14], and Qingdao Bay Bridge in China [15]. Several new technologies were developed on the basis of the concept of sustainable construction to solve these issues [16,17], such as temporary earth-anchor method [18], temporary stayed cables method [19,20], and temporary compressive strut method [21].…”

To promote sustainable development of civil infrastructures, minimizing environmental impact and mobility disruptions have been elevated to a higher priority during decision-making for bridge construction scheme. This study presents a novel temporary pylon-anchor (TPA) technology for construction of self-anchored suspension bridges by considering not only safety performance, but also environmental impacts. A practical assessment method and index of sustainability associated with bridge construction technology are established to facilitate the selection of construction schemes. The sustainability index takes the environmental impact, traffic disruption, onsite construction materials and equipment, onsite construction cost, and onsite construction risk into consideration. The sustainability index associated with both conventional and novel construction methods is assessed and compared in this paper. Specifically, a novel girder-pylon antithrust system (GPAS) is proposed, which is the crucial component of the TPA technology in engineering application. In addition, an analytical approach is developed, considering both global load-carrying capacity and local stress distribution within the design and construction of the GPAS. The applicability and rationality of the proposed construction technology are illustrated by the successful application in real-world engineering. The field tests and sustainability assessment during the construction stage reveal that the proposed sustainability assessment method and analytical approach can facilitate the implementation of sustainable construction for self-anchored suspension bridges by considering both construction safety and sustainability.

Accelerated Construction of Self-Anchored Suspension Bridge Using Novel Tower-Girder Anchorage Technique

et al. 2019

The traditional construction methods (e.g., erecting cable after girder) of self-anchored suspension bridge, can interrupt traffic during the construction stage due to the installation of temporary supports. That severely limits the wide application of this type of bridges. Thus, this study proposes a novel tower-girder anchorage (TGA) technique for accelerated construction of self-anchored suspension bridges. By using the proposed TGA technique, the mid-span girder segments are hoisted and connected to the hangers, which subsequently avoids the interruption of traffic during the construction period. The proposed TGA technique would reduce the construction cost, time of erection, and demolition of temporary scaffolds.To ensure structural safety and performance during the proposed construction process, the force transfer mechanism and construction process of TGA technique are assessed. To this end, the devices for TGA and system transformation are designed. The constructability of TGA technique on accelerated bridge construction is evaluated by a real-world application: Dongtiao River Bridge in China. A finite element model is established to analyze the construction process. Simulation analysis and field test data are compared. The comparison demonstrates that TGA technique can safely and economically achieve accelerated construction of self-anchored suspension bridges.
