“…Yang et al [9] showed that when using a single prestressed anchor in foundation pit engineering, the closer the anchor rope's position is to the foundation pit's center, the greater the anchor stress. Through the field inspection, Shen et al [10] investigated the performance of a deep foundation pit supported by suspended piles in soil and rock strata for a subway station in Qingdao Metro Line 3 in China. Many site-measured data are analyzed to investigate the horizontal displacement of piles at different depths under different construction stages.…”

Modeling the surface element and support system in deep excavation pits and investigating the deformation mechanism is an important issue. In this study, alternative solution methods for an anchored bored pile model are compared and discussed, and it is aimed to contribute to the studies to be carried out in the deep excavation area. A numerical analysis of retaining wall design is analyzed in the case of the Sivas cultural center building's deep excavation using GGU-Retain and Plaxis 2D software. Measured field data and simulated results are discussed. As a result, the bending moment and lateral deformation reach a maximum when the foundation pit is excavated to the bottom. It can be said that the lateral deformation value found with Plaxis 2D is within the allowable limits, closer to the field data, and provides sufficient quality. The research results will provide theoretical and practical experience for the optimal design and construction of similar deep excavation pits.

“…Afterward, they are placed in a high-temperature oven (ranging from 1000 to 1250 degrees Celsius) [5]. According to some pertinent studies on fiber reinforced soils, the studied percentages of polyester fiber content are (0%, 0.05%, 0.1%, 0.2% by weight) of the parent soil [6], carpet waste fibers (0, 0.2, 0.4, and 0.6% by weight of the soil) as a reinforcement agent on the soil behavior [7,8], scrap tire rubber and synthetic fibers (1, 2, 3, 4 and 5% by weight of the soil) of the parent soil [9]. Balegh et al studied mixtures prepared by tuff with 10, 20, 25, and 50% of powder ceramic [10].…”

Dredged sediments are a valuable natural resource used in construction and public works, however some dredged sediments do not have the physical and chemical qualities necessary for reuse, necessitating the addition of complementary materials such as ceramic waste powder. The main objective of this study is to improve the technical quality of sediments by adding ceramic waste powder and cement in low content by strengthening its mechanical and geotechnical properties. The present paper reports the treatment and recovery of dredged sediments with varying percentages of ceramic powder (Cp) and cement. Various properties such as maximum dry density, optimum moisture content, and California Bearing Ratio (CBR) are analyzed, the obtained results are compared with limestone Tuff. Investigations are performed using percentages of ceramic powder (Cp) at 2.5%, 5%, 7.5%, 10% and cement 5%. The results showed that there was an appreciable increase in strength and CBR values by the addition of Cp and cement. The research proved the effectiveness of the proposed method for constructing roads and pavements with low thickness.
