摘要
The method of onsite pouring is mostly adopted in current construction of traditional frame beam (TFB) structures, bringing adverse effects like poor supporting timeliness, low concrete quality, hard-coordinated deformation, complex working procedure, high construction risks, and so on. In order to solve these problems existing in the structure and construction of TFB, a new type of prefabricated frame beam (PFB) structure was given a brief introduction of its design and feasibility. Based on a slope supporting project in Guizhou Province, China, main points and techniques in the construction of PFB structure were summarized. Differences as well as pros and cons in the process of onsite construction of two kinds of supporting structure were discussed and analyzed. Results and monitoring data showed that the PFB structure has advantages over TFB structures in terms of the construction period, personnel and machinery, safety management, economic costs, CO2 emissions, supporting effects, and so on. The feasibility and stability of PFB structures in high slope supporting projects were verified, which lays a foundation for the popularization and application of prefabricated structures in similar slope supporting projects.
