Soil Mix Cutoff Wall Materials with Microcapsule-Based Self-Healing Grout
(ASCE, 11/1/2021)Over the last three decades, cutoff walls using soil mix technology have been developed and deployed to deliver in situ containment of contaminated sites. The aggressive contaminated soil environment imposes significant ... -
Validating the Generality of a Closed-Form Equation for Soil Water Isotherm
(ASCE, 12/1/2021)Total soil water potential ψt is conventionally defined as the sum of matric potential ψm and osmotic potential ψo, i.e., ψt=ψm+ψo, when gravitational potential is ignored. Soil water isotherm (SWI) is the constitutive ... -
Multipoint Traveling Wave Decomposition Method and Its Application in Extended Pile Shaft Integrity Test
(ASCE, 11/1/2021)Existing nondestructive pile integrity test (PIT) methods have certain limitations in the interpretation of test results for extended pile shafts supporting an existing structure. A novel multipoint traveling wave decomposition ... -
A Temperature-Dependent Model for Ultimate Bearing Capacity of Energy Piles in Unsaturated Fine-Grained Soils
(ASCE, 11/1/2021)This study presents an analytical framework to estimate the change in ultimate bearing capacity of energy piles in unsaturated fine-grained soils under drained mechanical loading conditions after drained heating. The ... -
Probabilistic Design Framework for Granular Filters
(ASCE, 11/1/2021)A granular filter is required to satisfy two requirements of retention and hydraulic conductivity. The current design approaches are based on the representative grain sizes for retention and hydraulic conductivity requirements. ... -
Uplift Behavior of Pipes and Strip Plate Anchors in Sand
(ASCE, 11/1/2021)This paper presents an experimental study on the uplift behaviour of both pipes and strip plate anchors buried in sand. A total of 24 plane-strain uplift tests were performed using an image-based deformation measurement ... -
Probabilistic Seismic Displacement Hazard Assessment of Earth Slopes Incorporating Spatially Random Soil Parameters
(ASCE, 11/1/2021)Permanent sliding displacement is a parameter that is used widely to evaluate the seismic performance of earthen slopes, and the inherent variability of soil strength parameters is considered simply using a logic tree in ... -
Uplift Resistance of Pipelines Buried in Compacted and Uncompacted Sands Using Field Tests
(ASCE, 11/1/2021)Upheaval buckling (UHB) is a common design issue for buried pipelines when the out-of-straightness of the pipeline combined with the high axial compressive forces induced by the extreme operating conditions causes the ... -
Geotechnical Analysis of a Mat Foundation Supporting a Wellhead Platform
(ASCE, 11/1/2021)China National Offshore Oil Corporation (CNOOC) currently is developing a mat-supported wellhead production platform concept as an alternative solution to conventional jacket platforms in shallow-water oil fields. The ... -
Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance
(ASCE, 11/1/2021)Preliminary estimations of shaft resistance of rock-socketed piles are usually conducted using empirical formulations that relate to the uniaxial compressive strength (σc) of the weaker material involved (intact rock or ... -
The Role of Liquefaction on the Seismic Response of Quay Walls during the 2014 Cephalonia, Greece, Earthquakes
(ASCE, 12/1/2021)Following the Cephalonia, Greece, 2014 earthquake sequence (Mw=6.1 and Mw=6.0), liquefaction of gravelly earthfill materials at the ports of Lixouri and Argostoli resulted in the manifestation of ground cracking and ... -
General Thermal Conductivity Function for Unsaturated Soils Considering Effects of Water Content, Temperature, and Confining Pressure
(ASCE, 11/1/2021)The thermal conductivity function (TCF) is an important constitutive function establishing the thermal conductivity–water content relationship in unsaturated soils. The existing TCFs do not account for the effects of ... -
Assessment of Existing SPT–CPT Correlations Using a New Zealand Database
(ASCE, 11/1/2021)Using a database of approximately 900 data pairs from 230 sites of co-located cone penetration test (CPT) soundings and boreholes with standard penetration tests (SPT) in the South Island of New Zealand, this paper assesses ... -
Experimental Investigation of a Load-Transfer Material for Foundations Reinforced by Rigid Inclusions
(ASCE, 10/1/2021)The rigid inclusion technique has been used worldwide to reinforce soft soil for road and railway embankments and deep building foundations. This technique is studied through field tests and physical and numerical models. ... -
Water Vapor Sorption Behavior of Wildfire-Burnt Soil
(ASCE, 11/1/2021)Wildfires and associated wetting-induced slope stability issues (i.e., erosion, shallow landslides, and debris flows) are common problems all around the world. The water-retention mechanism of the burnt soil after a ... -
Mitigating Lateral Spreading Forces on Large Foundations Using Ground Deflection Walls
