Flexural Behavior of Cold-Formed and Hot-Rolled Steel Sheet Piling Subjected to Simulated Soil Pressure
… the influence of transverse stresses from soil pressures on the longitudinal flexural strength. Four cross-sections with two pairs of equivalent sectional modulus were investigated. Sheet-piling specimens were subjected to simulated soil pressure from an air bladder loaded transversely to …

Einfluss der Bodenreaktionskraft beim Durchstanzen von Einzelfundamenten
… for different codes. The amount of the soil reaction to be deducted from the punching load differs from one code to another. The aim of the present investigation is to derive an advanced design model for the punching behaviour of footings taking into account the …

Numerical investigation of load transfer mechanisms in slopes reinforced with piles
… to use numerical analyses to evaluate the limit soil pressure on piles, to evaluate the load transfer mechanism, and to evaluate alternative means for estimating mobilized and limit loads on piles in piled-slope problems. It is found that limit forces predicted using 2-D, plane strain and 3-D …

Buried Pipe Life Prediction in Sewage Type Environments
… solution for transverse loading due to soil pressure in the case of buried pipe. The axial-symmetric stress analysis has been constructed taking into account the moisture content and the temperature of each ply of the laminate. The moisture diffusion model takes into account the geometry …

The influence of transplanting depth of head lettuce on size and shape of head
… of head was influenced by the added mechanical pressure of the soil around the plants. The compactness of head and conical shape of the deep transplanted plants appeared to be the result of soil pressure around the plant. Very compact heads, as observed on the deep treated plants, are …

Dynamic Testing of a Full-Scale Pile Cap with Dense Silty Sand Backfill
… developed under a no backfill condition. Passive soil pressure was measured using pressure cells and tactile sensors. It was concluded that the presence of the backfill significantly increased the lateral load resistance of the pile-cap system, with the resistance nearly doubling at a 50 mm …

Ground Improvement for Liquefaction Mitigation at Existing Highway Bridges
… behavior is influenced by excess pore water pressure migration, ground motion amplification, inertial force phasing, dynamic component of liquefied soil pressure, presence of a supported structure, and lateral spreading forces. Simplified, uncoupled analytical methods were unable to predict …

Distributed soil displacement and pressure associated with surface loading
Soil compaction is an inevitable result of agricultural practices. It alters physical properties of soil and tends to be undesirable as it adversely affects water and nutrient penetration. Furthermore, additional energy is spent to till the soil. Although a tremendous amount of research has been …

Predicting adverse geology and tunnel responses utilizing tunnel-ground interaction data with machine learning techniques
… tunneling practices mostly depend on limited subsoil investigation and monitoring data to deal with such uncertainties. In recent years, highly equipped tunnel boring machines (TBMs) have frequently collected machine-ground interaction data during excavation. The collected data can improve ground …

Guidelines for designing the overhead transmission tower foundations adjacent to cohesionless slopes
… response under combined loads and comprehensive soil characterization so as to attain experimental results and necessary soil parameters for numerical modeling; ii) developing, calibrating, and validating nonlinear three dimensional (3D) finite element models (FEMs) employing the results of …

Thermally-induced ratcheting behaviour of laterally-loaded reinforced concrete energy piles in sand
… changing the mechanical properties. In 1- soil-structure interaction tests, a model RC pile could serve as an effective heat exchanger for transferring heat from a heat-carrier fluid pipe embedded within the mortar to the surrounding sand. It exhibited accumulated and irreversible pile head …

Sustainable pavement applications utilizing quarry by-products and recycled/nontraditional aggregate materials
… aggregate subbase over soft subgrade soils; (3) using QB as a cement or fly ash-treated subbase (e.g., in inverted pavements); (4) using QB as a cement-treated base material; and (5) for base course applications, blending QB with coarse aggregate fractions of recycled materials and …
