Bridge and elevated structure
SYSTRA can provide the technical services for all aspects of bridge construction:
● Feasibility study
● Concept design
● Preliminary/detailed design
● Construction design
● Compilation of tendering documents
● Construction drawings design review
● Choice of construction method
● Construction supervision
● Upgrade and renovation design
● Technical transfer
In the course of providing technical services, SYSTRA experts always try their best to meet the requirements of the owners:
● Harmonize with the urban landscape (both suburban and urban)
● Esthetic structure design
● Reasonable construction method and tight construction planning
● Cooperate closely with other technical departments of SYSTRA to ensure that the functional requirements of the structure are met
● Optimization of construction cost
SYSTRA’s experts can carry out thematic research according to the special needs of the project, for example, in the high speed railway projects:
● Vibration analysis
● Rail-structure interaction analysis
● Thematic research on passenger comfort
The bridge structures designed by SYSTRA adopt a wide range of construction technology:
● Reinforced concrete bridge structure
● Prefabricated concrete bridge structure
● Steel bridge structure
● Steel-concrete composite bridge structure
SYSTRA participated in the design of various forms of road bridges or railway bridges:
● Simply supported beam structure
● Segment prefabrication structure
● Full span prefabrication elevated structure
● Truss bridge
● Arc bridge
● Frame structure
● Cable-stayed bridge
● Suspension bridge
Tunnel and underground works
Comprehensive project design
● Integral design of transport system
● Design of multi-modal transfer hub
● Design of tunnel cross-section
Line insertion of difficult sections
When studying the insertion of transport line, especially when the line needs to go through dense urban areas, SYSTRA experts need to consider not only the harmony between engineering and the overall urban environment, but also need to take into account a variety of restrictions and risks that may occur during the construction.
The construction method shall conform to the design requirements and construction conditions. Whether the construction method is reasonable or not will directly affect the investment of the project and the success of the project. In terms of tunnel construction methods, SYSTRA experts have accumulated rich practical experience:
● Cut-cover excavation method
● Traditional construction method of tunnel sections and stations
● TBM method (Compressed-air, mud-water or soil-pressure balanced shield)
● Special construction method
● Immersed pipe, pile foundation replacement, soil treatment
