A case study of strut-free excavation retaining system
https://orcid.org/http://orcid.org/0000-0001-8225-4861
This paper presents a successful design of a strut-free excavation retaining system, namely the TPKE project. The TPKE excavation project was 13.2 m deep, covering approximately 127 × 105 m which is considered as a large excavation. Considering the cost saving and construction period shortening, the configurations of the diaphragm walls, buttress walls, cross walls, and the capping slab were used to design a strut-free excavation retaining system. This is feasible through the three-dimensional finite element analysis. This project was successfully completed with the maximum diaphragm wall deflection to the excavation depth ratio of 0.25%. A set of parametric studies was conducted to investigate the mechanism of this retaining system. For reducing wall deflections, it can be concluded that increasing the number of cross walls and increasing the length of the buttress walls was more effective than increasing the number of buttress walls. Moreover, increasing the depth of buttress walls below the excavation level was insignificant to reduce wall deflections.
