Zhang, J; Zhou, Q and Zhang, S (2022) Case study of field application of prefabricated anchoring frame beam structure in slope supporting projects. Journal of Construction Engineering and Management, 148(9): 05022008, ISSN 0733-9364
Abstract
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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
