A New Strategy for Mitigating Pipeline Uplift in Liquefied Soils
Author(s) Luca Flessati, Pietro Marveggio, Claudio di Prisco, and Domenico De Sarno Abstract Seismic-induced liquefaction is one of the main hazards for pipelines buried in saturated granular materials. When soil is partially or completely fluidized, a...
Suitability of Various Ureolytic Microbes for Potential Soil Strengthening via Biocementation
Author(s) Surabhi Jain Abstract Biocementation or microbially induced calcium carbonate precipitation (MICP) is a feasible biochemical process in enhancing the behavior of geomaterial, that is, soil strengthening and/or remediation. This biochemical process...
Modelling Tunnel Squeezing Using Gene Expression Programming: A Case Study
Author(s) Mohammad Hossein Kadkhodaei Ebrahim Ghasemi Saeed Mahdavi Abstract Squeezing is a well-known geotechnical phenomenon in the excavation of underground spaces, especially tunnels. Squeezing occurs under different geotechnical conditions in weak rock...
Experimental and Numerical Study of the Dynamic Mechanical Behavior of Fully Grouted GFRP Rock Bolts
Author(s) Wenjie Wang Longzhe, Chaoshui Xu, Chao Liu, Hao Wang and Jingting Abstract Due to good corrosion resistance and high tensile strength, glass fiber–reinforced plastic (GFRP) bolts are widely used in mining operations. However, GFRP bolts are...
Environmental and Geotechnical Properties of Lightweight Aggregates Made of Reused Solid Wastes
Author(s) Daniela Dominica Porcino, PhD Giuseppe Tomasello, PhD Francesco Mauriello, PhD Angela Malara, PhD Abstract This paper presents the environmental and geotechnical characterisation of new synthetic lightweight aggregates (SLAs) composed of reused...
Effects of Fibre Additions on the Tensile Strength and Crack Behaviour of Unsaturated Clay
Author(s) Jianye Wang, PhD Paul N. Hughes, MSc, PhD Charles E. Augarde, BSc, MSc, DPhil, CEng, FICE Abstract Desiccation cracking in clay soils is a combined mechanical and hydraulic problem and such soils can be improved by various methods including...
Characteristics of Cyclic Undrained Model SANISAND-MSu and Their Effects on Response of Monopiles for Offshore Wind Structures
Author(s) Haoyuan Liu* Amir M. Kaynia† Abstract Optimised design is essential to reduce the cost of monopiles for offshore wind turbines. For this purpose, an in-depth understanding of the behaviour of monopile–soil interaction is required. As more wind farms...
Stabilisation of a Clay Soil by Injection of Cifferent Ions
Author(s) Ali R. Estabragh Amir Kazemi Akbar A. Javadi Mohammad Moghadas Abstract In this research study the effects of calcium and magnesium ions on stabilisation of a clay soil were studied by conducting a set of laboratory tests. A special apparatus was...
Lateral Load Response of Large-Diameter Monopiles in Sand
Author(s) Qian Hu*† Fei Han†‡ Monica Prezzi† Rodrigo Salgado† Minghua Zhao* Abstract Due to the increasing demand for renewable clean energy, there has been rapid growth in the development of offshore wind energy resources in recent years. The majority of...
