Finite element study of geosynthetic encased stone columns in sensitive soft clay
Some normally consolidated soft soils manifest strength sensitivity, ie these soil manifest strain softening when shear in an undrained mode. These soils, referred to as sensitive soft soils, have the typical features of strain hardening in drained shearing and strain softening in undrained …

Putting Place Back Into Displacement: Reevaluating Diaspora In the Contemporary Literature of Migration
… order to improve the engineering properties of soft soils, materials, such as cement and fiber, can be introduced to the soil mass. Currently, design criterion for a cement-soil mixture requires only the measurement of unconfined compressive strength. This simple measurement may not be adequate …

An investigation of the effect of dynamic and static loading to geosynthetic reinforced pavements overlying a soft subgrade
Construction of roads over soft soils can lead to design and construction related problems linked to the soil's compressibility characteristics and low strength. Failure, in terms of bearing capacity can occur when pavements are constructed over such soft soils. When road pavements, which are …

The sticky property of Ypresian clays
… with the underlying soil, and excavating in soft soils is one of them. One major issue when managing soft soils is clogging, which occurs because cohesive soils tend to adhere to the cutting head of tunnel boring machines or to the cutting wheel of hydromills. This thesis focuses on Ypresian …

Development of instrumented oedometer incorporated with bender element and electrical conductivity
Soft soils are normally associated with high moisture content and fine-grained particles possessing poor geotechnical properties such as low shear strength and high compressibility. Solidification, using hydraulic binders could be adopted to improve these poor properties. The compressibility of …

A case study on the performance of embankments on treated soft ground
… involves construction of embankments overlying soft clay and peat deposits with very stringent requirements on the time frame of construction and allowable settlements. A field program of instrumented test embankments, referred to as No-Recess, has compared the performance of five schemes for …

Guidelines for the Use of Expanded Polystyrene (eps)-Block Geofoam for the Function of Lightweight Fill in Road Embankment Projects
… alternative for construction of embankments over soft ground. The ultimate benefit of this is an optimization of both the technical performance as well as cost of EPS-block geofoam embankments. The research has confirmed that EPS-block geofoam can provide a safe and economical solution to problems …

Development of truck tire-terrain finite element analysis models.
… and minimizing fuel consumption, particularly on soft soils. Recent advances in finite element analysis and computational efficiency have opened doors to highperformance, highly complex simulations which were not possible just a few years ago. This research aims to model two tires using non-linear …
