Microbial Mineralization and Carbonation Consolidation of Dredger Fill and Its Mechanical Properties
Publisher: ASCE
Abstract: Streptomyces-induced calcite precipitation (SICP) was used to bind loose dredger fill into soil columns. The composition, microstructure, strength, and permeability of the soil columns were studied. The X-ray diffraction ...
Uncertainty Analysis in Predicting Differential Settlement at the Interface between Bridge Deck and Subgrade
Publisher: ASCE
Abstract: This work involved an uncertainty analysis of a case study of a bridge in the Wenzhou area of China. A pile–slab composite foundation was used to mitigate the bump at the end of the bridge. The uncertainty analysis was ...
Compressibility Evaluation of Reconstituted Clays with Various Initial Water Contents
Publisher: American Society of Civil Engineers
Abstract: Understanding the compressive behavior of reconstituted clays plays the central role for many infrastructures, particularly for those built in coastal areas. This paper presents an enhanced approach for the determination ...
Experimental Study on Strength and Microstructure of Cemented Soil with Different Suctions
Publisher: American Society of Civil Engineers
Abstract: The use of cement as curing agent to increase the strength of soft ground and reduce the deformation of soft soils has been widely adopted in soft soil engineering. The cemented soil is eventually exposed to the air, and ...

Publisher: American Society of Civil Engineers
Abstract: The use of cement as curing agent to increase the strength of soft ground and reduce the deformation of soft soils has been widely adopted in soft soil engineering. The cemented soil is eventually exposed to the air, and ...
Strength Characteristics and Micropore Structures of Residual Soil with Different Suctions
Publisher: ASCE
Abstract: This paper presents micro–macro behaviors of unsaturated residual soils within high suctions. A series of unsaturated soil specimens was prepared using the saturated-saline-solution-based vapor equilibrium technique, ...
Analytical Solution for Pollutant Diffusion in Soils with Time-Dependent Dispersion Coefficient
Publisher: American Society of Civil Engineers
Abstract: According to the characteristics of the time-dependent dispersion coefficient of pollutant migration in soils, a one-dimensional pollutant migration model considering solute decay is established in the finite thickness ...
