A novel experimental program was undertaken to explore crack development inside an expansive soil column under cyclic Wetting and Drying (W-D) its influences on the Soil-Water Characteristic Curve (SWCC). Experimental investigations revealed that in first drying cycle, fine evenly distributed cracks developed from initial defects upper surface. In subsequent cycles, unhealed during wetting cycle further grow width, length depth while initiation zone of new limited. The characteristics within...
ABSTRACT Rigid pile composite foundation (RPCF) has been widely used in Yellow River Alluvial Plain (YRAP) due to remarkable reinforcement and economical effects. However, current design of RPCF this area are typically based on saturated soil mechanic principles assuming drained condition, despite the fact that is unsaturated condition. Due long time water scouring, silt YRAP generally exhibits high particle sphericity poor gradation. Even after standard compaction, it still a relatively...
Abstract Structural Health Monitoring (SHM) systems for mega‐bridges play a critical role in modal identification, damage detection, and safety assessment, providing essential information decision‐making. Despite significant advancements SHM technology mega‐bridges, monitoring these structures highly complex environments still requires continuous improvement. For the Moon Bay Bridge, which exists particularly environment, two primary focuses have been identified: real‐time GNSS...
Lateral swelling pressure (LSP) can pose significant threats to the safety and stability of geo-infrastructure. For this reason, it is necessary take into account influence LSP in design geo-infrastructure such as basement walls, retaining pile foundations, pipelines built within or adjacent expansive soils upon water infiltration. A relationship developed calculate free from vertical (VSP), which be measured conventional laboratory tests. This extended (1) lateral earth (LEP) behind a...
A comprehensive experimental program was performed in order to understand the mechanical behavior of model piles associated with water infiltration collapsible loess. Real-time measurements were recorded for pile head settlement, shaft friction, and base resistance, as well soil behavior, including volumetric content, suction. The results suggest that both settlement resistance increased infiltration. linear axial force distribution gradually changed a "D" shape, maximum occurring middle...
Pile foundations are widely designed extending principles of saturated soil mechanics assuming drained conditions (i.e. effective stress) even in expansive deposits despite the fact around pile is a state unsaturated condition. The mechanical behavior in-situ significantly influenced by suction changes associated with water infiltration. In this paper, single model variations an under service load were investigated. Experimental results suggest settlement increases due to Such phenomenon can...
Pile foundations are widely used in regions with expansive soils to transfer the loads from superstructures a rigid soil stratum, thereby alleviating stability and deformation problems. However, current design procedures for pile typically based on saturated mechanics principles assuming drained conditions, despite fact surrounding piles an unsaturated state. Volume changes of induced by matric suction upon seasonal wetting drying can significantly influence load-transfer mechanisms. In this...
Lateral swelling pressure (LSP) develops in expansive soil when the volume expansion associated with water infiltration is restrained horizontal direction due to a rigid infrastructure. Various types of testing techniques, used determine LSP from both laboratory and field studies, are critically reviewed by focusing on two key factors, namely, boundary conditions saturation path. Most techniques capable reasonably simulating stress state element behind retaining structure applying fixed...
Elevated levels of atmospheric CO2 (eCO2) promote rice growth and increase methane (CH4) emissions from paddies, because increased input plant photosynthate to soil stimulates methanogenic archae. However, temporal trends in the effects eCO2 on CH4 are still unclear. To investigate changes over time, we conducted a two-season pot experiment walk-in chamber. Positive leaf photosynthetic rate, biomass, grain yield were similar between growing seasons. decreased time. by 48%–101% first season,...
The rigid long-short-pile composite foundation has been increasingly used as an effective and low-cost reinforcement method. pile-soil interaction in this type is more complicated than that the equal-length pile foundation. In study, several physical model tests were conducted to investigate synergistic mechanism of A comparative analysis was static load test data single-pile long-short foundations assess load-bearing characteristics stiffness evolution unit. result indicated a positive...
Computer modelling of fire has become an attractive approach for the safety assessment proposed building structures. To devise and validate model, a general–purpose computational fluid dynamics (CFD) software package, CFX, been evaluated against test case in ventilated room. The room is 6.0 m long, 4.0 wide 4.5 high with exit opening 0.65 x m. A simple inert model used, which constant volumetric heat release introduced at location source to represent fire. Combustion chemical reactions are...
Pile foundations are widely used in all types of soils including expansive and collapsible that typically found nature a state unsaturated condition. Opposite trends volume change behavior observed when water infiltrates into soils. The design pile these is conventionally based on saturated soil mechanics assuming drained conditions ignoring the influence conditions. In this study, infiltration tests were performed two model piles; one piles was tested an other soil. focus study to determine...
Lateral swelling pressure (LSP) develops when expansive soil volume increment associated with water infiltration is restrained in a confined domain, for example, due to construction of civil infrastructure. In this paper, initially flowchart developed highlight various key factors that influence the LSP mobilization according lab and field studies collected from previous literature studies. Then extending unsaturated mechanics, theoretical framework proposed illustrating against retaining...
