Calculated versus measured static capacity for two pile types
(University of Missouri--Columbia, 2018)The Missouri Department of Transportation decided to replace two bridges in northeast New Madrid Country, Missouri. The bridges were in service for approximately 50 years and both were founded on driven piles. The bridge ... -
Determination of the scale of fluctuation of cone penetration test data obtained from an alluvial site in Missouri
(University of Missouri--Columbia, 2018)To account for uncertainty in geotechnical projects, knowledge of the uncertainties should be understood. Many sources of uncertainties can be reduced with increased sampling and good practices, but due to the nature of ... -
Determining the relative effects of volumetric water content and dry density on the dielectric constant of soils
(University of Missouri--Columbia, 2011)Non destructive subsurface investigation using electromagnetic (EM) waves is a growing technique in geotechnical engineering (Mohamed 2006). The ability to "see" under the Earth's surface without having to excavate is ... -
Estimating the rock mass modulus of Missouri shale using pressuremeter tests
(University of Missouri--Columbia, 2017)Rock mass modulus can be a useful property in the design of foundations. Rock mass modulus is defined as the stress strain response of a rock mass in-situ. The stress strain response of the rock mass can be estimated by ... -
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located ... -
Field performance of instrumentation for monitoring effects of timber harvesting on water quality
(University of Missouri--Columbia, 2006)Water samples from ephemeral streams and associated hillsides are being collected to quantitatively determine the impact of Regenerative Oak Clear Cutting (ROCC) on water quality and sediment and nutrient transport in ... -
Forecasted versus in situ dielectric constants for soil
(University of Missouri--Columbia, 2016)Some nondestructive testing (NDT) techniques in civil engineering applications employ electromagnetic (EM) wave methods. These techniques have proven to be effective for many applications including investigating and ... -
Geotextile separators for dust suppression on gravel roads
(University of Missouri--Columbia, 2006)Dust can be a health concern because of its potential to contain respirable particles. The US EPA and state environmental agencies developed and implemented a reporting system for the amount of particulate (PM10) derived ... -
Geotextile wrap-face wall using marginal backfill
(University of Missouri--Columbia, 2006)A concrete retaining wall was constructed during October/November 2005. The height of the wall was 9 feet with a stem width of 0.83 ft, while the width of the base was 1.83 ft. The backfill was a low plasticity clay (CL). ... -
LRFD for settlement analyses of shallow foundations and embankments-developed resistance factors for consolidation settlement analyses
(University of Missouri--Columbia, 2014) -
Performance observations of geosynthetic reinforced bridge abutments
(University of Missouri--Columbia, 2015)Geosynthetic Reinforced Soil - Integrated Bridge System (GRS-IBS) is a technology which has been around for almost 40 years in the United States but is now being pushed by the FHWA due to improved performance and promised ... -
Post-construction verification of hydraulic conductivity of soil in an earthen dam
(University of Missouri--Columbia, 2018)Earthen dams are used throughout the country to hold back flood waters from cities, towns, and farmlands, make reservoirs to supply drinking water, and create lakes for recreational purposes. The hydraulic conductivity of ... -
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to ... -
Predicting surface water profiles in sand
(University of Missouri--Columbia, 2015)Electromagnetic (EM) wave methods are used in many civil engineering applications for non-destructive investigations such as locating reinforcing steel and voids in concrete, sinkholes, buried utilities, the groundwater ... -
Reliability-based design (RBD) of shallow foundations on rock masses
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The reliability-based design (RBD) approach that separately accounts for variability and uncertainty in load(s) and resistance(s) can be incorporated ... -
Reliability-based versus allowable stress design of foundations for the Center for Missouri Studies building
(University of Missouri--Columbia, 2017)Uncertainty in design parameters is inherent to the field of geotechnical engineering. Allowable stress design has conventionally been used for foundation design and accounts for uncertainty in geotechnical parameters and ... -
Shear strength of flue gas desulfurization by-product
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Shear strength parameters of flue gas desulfurization (FGD) sludge were investigated by conducting a series of constant volume direct simple shear tests ... -
Shearing rate effects on drained shear strength of flue gas desulfurization (FGD) byproduct
(University of Missouri--Columbia, 2014) -
Uncertainty propagation and parameter sensitivity analyses of relative permittivity models for use in soils
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nondestructive subsurface investigations are becoming more popular in geotechnical engineering ranging from agricultural applications to environmental ...
