The behaviour of modern flexible framed structures undergoing differential settlement
… load bearing walls and are less susceptible to differential settlement damage. The use of conventional guidelines for differential settlement on modern flexible framed structures may therefore be over-conservative. The literature review of the study highlights the factors producing differential …

Foundation settlements of English cathedrals
… geotechnical components that contribute to the settlement of English cathedrals are analyzed. The stress at the base of tower and nave piers was found and compared to the allowable bearing capacity. The expected settlement range of each cathedral's tower and nave piers was calculated by …

Modelling Transition Zones and Optimal Design Adjoining Tunnels and Bridges
… impact forces. As a result, there is a higher differential settlement, which can cause an abrupt change in the structural response of the track due to variations in stiffness and track damping. This can cause accelerated deterioration of track material and geometry, leading to reduced …

Controlled Low-Strength Material (CLSM) produced from limestone fines and other byproducts
… responsible for various issues related to differential settlement. Some of the most important causes of differential settlement are compression of poorly compacted embankment soils, poor material characteristics, non-homogeneity of embankment soils, and erosion of underlying soils. …

Optimization of the bottom plate of a ground-supported liquid storage tank
Several tanks have failed due to intolerable differential settlements, causing major problems in most cases. The objective of this study is to optimize the bottom plate of the tank so that the differential settlements are reduced to a minimum. Circular plates on an elastic half-space are …

Critical height and surface deformation of column-supported embankments
… can be used in soft ground conditions to reduce settlement by transferring the embankment load to the columns through stress redistribution above and below the foundation subgrade level. Column-supported embankments are typically used to accelerate construction and/or protect adjacent facilities …

Enhancing the engineering properties of expansive soil using bagasse ash, bagasse fibre and hydrated lime
… FRLTP could effectively reduce the total and differential settlements, and the lateral displacement of the embankment by 20%, 74% and 46%, respectively, when compared with the embankment without FRLTP. Subsequently, several series of extensive parametric studies on the influence of FRLTP …

DEM Study of a Single Stone Column in a Clayey Stratum
… the bearing capacity and reducing the total and differential settlement of foundations supported on compressible soils. The piers are composed of a series of vibrationally compacted aggregate lifts from a desired depth up to the finished foundation level. The shear strength of the coarse-grained …

Water intrusion in underground structures
… the surrounding environment (consolidation and differential settlement). Spalling is one of most common structural damages due to groundwater infiltration. The presence of water can cause unpleasant stains, resulting in erosion and corrosion over time. Formation of icicles, ice and water ponding …

Ground penetrating radar characterization of wood piles and the water table in Back Bay, Boston
… a structure's foundation and often result in differential settlement or cracking in walls or foundations. The current method of investigating suspected pile failure is to excavate a foundation and to physically inspect the piles, noting the elevation of the water table. In many cases, …

Track model for predicting dynamic responses of railroad bridge approaches
… model, study problems associated with differential settlement, hanging ties, impact loads and various lack of support conditions, select mitigation methods for existing deficiencies, and as a result, formulate improved bridge approach designs. The first task in this PhD study involved …

Integrated computational and experimental framework for the assessment of railroad ballast life-cycle behavior
… through field testing efforts; ballast settlement trends computed from the full-scale track numerical simulations were compared with the actual ballast settlements measured in the Transportation Technology Center (TTC) High Tonnage Loop (HTL) field tests. An application of this …

Bridge approach slab analysis and design incorporating elastic soil support
The development of equations necessary for the analysis of finite bridge approach slabs (BAS) on elastic soil support is reported in this thesis. Results are compared for moments and shear forces governing the design for a wide range of values of soil elastic modulus ranging from dense sand to very …

Evaluation of seismic Vulnerability and Strengthening of heritage Buildings. Case Study: The Giralda of Seville
… activities. To do so, first, the historical settlements of the tower has been assessed. A detailed characterisation of the foundation and its geotechnical model has been carried out. Both 2D and 3D Finite Elements Model (FEM) has been developed to analyse the settlements, considering the …

Analyses and modeling of track transition site responses from instrumented bridge approaches
… are caused by stiffness variation and inevitable differential settlement accumulation between a railroad bridge and track. Although many studies have investigated this bridge approach problem, a permanent effective solution is yet to be agreed upon among researchers. This Ph.D. dissertation aims …

Foundation response to ground movements induced by tunnel excavation
… Rail Link project. The development of surface settlement, transient subsurface heave and additional settlement due to the cessation of tail-skin grouting were considered in the analysis. It was found that realistic stress paths and induced axial forces consistent with field measurements could …

Static and Dynamic Performance of Biochar Enhanced Cement Stabilised Peat
… as they significantly increase the risk of large differential settlement. In countries like Malaysia and Indonesia where peat covers about 8 and 14% of the land areas, it is not always possible to avoid construction on peaty regions. Geotechnical engineers have developed several techniques to …
