A Three Dimensional Discretized Tire Model For Soft Soil Applications
… to the modeling due to the interaction with the soft soil. In such situations, one must account for the soil dynamics and its impact on the tire forces, in addition to those aspects considered for an on-road tire. The goal of this project is to develop an accurate and comprehensive, while also …

Systematic Tire Testing and Model Parameterization for Tire Traction on Soft Soil
Tire performance over soft soil influences the performance of off-road vehicles on soft soil, as the tire is the only force transmitting element between the off-road vehicles and soil during the vehicle operation. One aspect of the tire performance over soft soil is the tire tractive performance on …

Stability of Embankments Founded on Soft Soil Improved with Deep-Mixing-Method Columns
Foundations constructed by the deep mixing method have been used to successfully support embankments, structures, and excavations in Japan, Scandinavia, the U.S., and other countries. The current state of practice is that design is based on deterministic analyses of settlement and stability, even …

Soft Soil Stabilisation Using a Novel Blended Cementitious Binder Produced From Waste Fly Ashes
Soil stabilisation is one of the most common techniques used to mitigate the undesirable properties of soft soils such as low compressive strength and high compressibility. Cement is the most commonly used binder for soil improvement applications in the UK and worldwide due to its high strength …

Prediction of the off-road rigid-ring model parameters for truck tire and soft soil interactions
… tire and SPH (Smoothed Particle Hydrodynamics) soil interaction modeling techniques. The in-plane and out-of-plane off-road rigid-ring parameters are predicted for an RHD (Regional Haul Drive) truck tire at varying operating conditions. The tire model is validated through static and dynamic …

Characterization of soft soil using multi-channel analysis of surface waves (MASW) and electrical resistivity method (ERM)
This thesis demonstrates the research on the soft soil characteristics using geophysical methods. The need on non-intrusive, time efficient, economic and larger volume of investigation had increased the demand of using geophysical methods for geotechnical investigation. The research concentrates on …

The formation, properties and behaviour of coastal soft soil deposits at Perlis and other sites in peninsular Malaysia
Peninsular Malaysia coastal soft soil deposits have their own unique characteristics and properties which are quite different from other tropical and temperate soft soil deposits. This research study reviews the formation of coastal soft soil deposits with emphasis on the formation of Peninsular …

Impact of Curing Time and Curing Stress On the Mechanical Behavior of Cement-Improved and Cement-Fiber-Improved Soft Soil
… 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 …

Soil compaction of peat under the influence of electrokinetic stabilization (EKS) treatment
… Peat is considered as one of the problematic soil in construction projects all over the world, which covers about 4% land of the whole world while 8% of the total area of Malaysia and about (5.86%) of peat soil existing in Johor state. Low shear strength of peat may lead to massive loss of …

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 …

Three-Dimensional Analysis of Geogrid Reinforcement used in a Pile-Supported Embankment
… that is utilized when sites are limited by a soft soil or clay. In this system, an embankment is supported by a bridging layer, consisting of granular fill and one or multiple layers of geogrid reinforcement. The bridging layer transfers the load to piles that have been driven into the soft …

Application of rate dependent soil model, MIT-SR, for evaluation of long-term ground movements due to consolidation and creep
… predictions of settlements of compressible soil strata are based on results of laboratory element tests on small test specimens. Ladd et al. (1977) show that scaling of laboratory consolidation tests to field scale is strongly affected by assumed creep properties of the clay, leading to …
