The existing Beijing Pingguoyuan Subway Station was extended through a extension project. excavation for the located directly above station. Complex interactions exist between structure and retaining pile wall of excavation. Based on this project, three-dimensional finite element models were established to investigate mechanical characteristics embedded non-embedded walls. A parametric analysis performed both types stress deformation walls structures analyzed. results show that when bottom...
Microbially induced carbonate precipitation (MICP) has been utilized as a new method to improve loess soil strength. In this study, we investigated the influence of main parameters on shear strength MICP-treated specimens. Initially, culture media with different formulas and pH values were examined identify most efficient medium for soil. To explore behavior under general stress levels, unconfined compressive (UCS) tests triaxial relevant compression vertical loads performed calcium sources,...
Saline soil is characterized by high concentrations of soluble salts, which can pose hazards such as frost heaving, uneven thaw settlement, and concrete erosion, especially subjected to freeze-thaw (F-T) cycles in the seasonal frozen regions. This study aims at investigating cement micro-silica treatments effect on changes microstructure, strength property durability compacted saline soil, evaluating suitability potential industrial waste materials for altering mechanical behaviors...
Regarding a novel and low-carbon composite pile, the MgO-carbonated pile (MCP) is formed by pervious concrete (inner core) at center of deep magnesia (MgO) mixing column (outer subjected to forced carbonation. The shaft resistance MCP primarily governed interface concrete–carbonated soil. Understanding interface's shear behavior strength crucial for design safety assessment MCP. In this paper, series direct tests were conducted analyze behaviors soil interface. aim was evaluate impact key...
Red clay with features of high liquid (plastic) limit, low permeability, medium-low compressibility and strength is widely used in anti-seepage projects including roadbed, earth dam, tailings landfill cover. This study investigates the hydraulic conductivity propagation desiccation cracks compacted red Dalian, China, considering effect freeze-thaw (F-T) cycles saline intrusion. A series specimens were subjected to different F-T at various controlled salt concentration 0.2% 4%. The surface...
This study presents a novel construction pre-supporting system for large underground space excavation with shallow depth, Steel Tube Slab (STS), in which adjacent steel pipes are connected by couple of flanges, bolts and concrete flexural capacity lateral stiffness the whole structure. The STS method is employed first time ultra-shallow buried span subway station China, during ground settlement structural deformation monitored. A numerical model established reliability verified monitored...
Experimental studies about the flexural performance of channel steel tube slab (CSTS) structure subjected to concentrated loads were carried out, with considering various spacing adjacent tubes, longitudinal between and missing tensile steel. A self-designed device equipped particle image velocimetry (PIV) technology was used monitor continuous deformation concrete cracking characteristics. In this study, mechanism CSTS serving in underground engineering analyzed, a theoretical model for...
Recent advancements in text-to-image generation have been propelled by the development of diffusion models and multi-modality learning. However, since text is typically represented sequentially these models, it often falls short providing accurate contextualization structural control. So generated images do not consistently align with human expectations, especially complex scenarios involving multiple objects relationships. In this paper, we introduce Scene Graph Adapter(SG-Adapter),...
Carbonation technology using MgO and CO2 has been considered a rapid, effective, environmentally friendly method for improving weak soils, mainly applied in shallow foundation treatments. This study introduced novel MgO-carbonated composite pile (MCP) technique developed by injecting through gas-permeable pipe into MgO-mixing column carbonation solidification its applications subgrade Several field tests were carried out to the characteristics of MCP as well performance MCP-reinforced...
As the composite pile, precast concrete piles reinforced with cement-treated soil (PCCS) is formed by driving cement (PC) pile into deep mixing (DM) column, which has been successfully and widely utilized to support buildings embankments over soft soil. To increase spacing give full play economic merits of PCCS, a reinforcement scheme, involves combined use rigid flexible columns, employing penetrated PCCSs floating DM columns proposed for ground treatment. However, there lack feasible...
