Brief introduction of the special prize and first prize projects led by the design institute

"Key Technologies for Building Shield Tunnels in Complex Environments" project

In this project, a scale-down simulation test platform was developed for the impact of shield construction on adjacent pile foundations and fault dislocation on tunnels, and a prediction model of shield tunnel construction parameters was proposed to determine the design and construction parameters of shield tunneling. The dual-mode shield machine, shield machine refrigerated cutterhead and other equipment have been developed to enhance the adaptability of the shield machine to complex formations. For a variety of engineering scenarios, construction methods such as shield tunneling through sensitive structures and complex stratum environments have been developed, and a technical system for risk control of crossing engineering in complex environments has been formed.

The project has published 14 papers, published 2 monographs, authorized 14 invention patents, and approved 6 provincial construction methods, filling the gap in the key technologies of shield tunnel construction in complex environments, and the relevant research results have been successfully applied in Guangzhou, Foshan and other urban rail transit projects and intercity railway projects.

Research and Application of Key Technologies of New Large Space Steel Support System for Foundation Pits Based on the Dual Carbon Goal

In view of the problems existing in the traditional support system, this topic proposes a new large-space steel support system technology for foundation pits. Combined with the actual project in the Greater Bay Area, the application of the new steel support system was studied by means of theoretical calculation, on-site monitoring, numerical simulation and other methods, and the results were promoted and applied in the new steel support system in large space.

For the first time, a new truss-type steel composite support system was developed, and the simplified calculation theory of support was proposed. It is the first to create a series of steel pipe composite support system products and improve the calculation theory research; The multi-point linkage synchronous loading and holding system was developed to solve the problem of accurate and efficient loading of steel supports; Research and development of prefabricated support series products to solve the shortcomings of the traditional system and improve the quality of green foundation pits; Research and development of a new type of steel support system parametric software based on the enterprise, real-time linkage with the enterprise resource library, to achieve design, construction, resources three synchronous linkage optimization combination.

"Flexible high pier construction alignment under the effect of sunshine temperature

Key Technologies for Control and Quality Assessment".

For the first time, the virtual excitation method and the least squares method were used to analyze the influence of sunshine temperature on the temperature field gradient of flexible high piers. A new theory of constrained stiffness identification and quality assessment of flexible high piers was proposed, and the calculation and control method of pier alignment was innovated, which improved the accuracy of pier quality assessment and the efficiency of alignment correction. A set of intelligent information management system has been developed, and the Internet of Things technology has been integrated to realize the full-cycle intelligent monitoring and early warning of the alignment and quality of bridge pier construction.

The project achievements include 3 invention patents, 6 utility model patents, and 6 high-quality papers (3 SCI, 2 EI, 1 Chinese core). The above results have been applied in a number of engineering projects, effectively improving the construction quality and efficiency, shortening the construction period, reducing costs, and producing significant social and economic benefits.

This award is a full affirmation of the scientific and technological innovation ability of Guangzhou Metro Design and Research Institute. The design institute has always regarded scientific and technological innovation as the core driving force of enterprise development, and will continue to strengthen the core main position of enterprises in scientific and technological innovation in the future, comprehensively enhance scientific and technological innovation capabilities by increasing key core technology research efforts, undertaking major scientific and technological innovation projects, introducing and applying advanced technological achievements, and strengthening scientific research team building, so as to lead the technological innovation of urban construction and rail transit industry, and strive to become a leader in comprehensive scientific and technological services for urban construction and rail transit, and build a world-leading design consulting enterprise.
