RISEffects of Clay Creep on Long-Term Load-Carrying Behaviors of Bored Piles: Aiming at Reusing Existing Bored Piles
Publisher: ASCE
Abstract: An analytical procedure is presented for assessing the long-term load-carrying behavior of bored piles in clay, where the plastic volumetric strain of surrounding clay caused by creep is estimated by an advanced ...
Analysis of Shaft Resistance Setup of Driven Piles in Soft Sensitive Clays Considering Soil Consolidation and Creep
Publisher: ASCE
Abstract: Soft sensitive clays around a pile shaft experience destructuration during pile installation, excess pore pressure (u) dissipation, and creep after pile installation, but their influence on pile shaft resistance is difficult ...
Influence of Exposure Temperature on Chloride Diffusion into RC Pipe Piles Exposed to Atmospheric Corrosion
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on the influence of exposure temperature (21, 30 and 50°C) on chloride diffusion into reinforced concrete (RC) pipe pile exposed to atmospheric corrosion. The governing equation of chloride diffusion ...

Performance of a Zoned Excavation by Bottom-Up Technique in Shanghai Soft Soils
Publisher: American Society of Civil Engineers
Abstract: This paper investigates a basement excavation adjacent to running metro tunnels and underground pipelines in Shanghai soft soil. The zoned excavation technique was adopted to control the deformations caused by excavation. ...
A Generic Analytical Elastic Solution for Excavation Responses of an Arbitrarily Shaped Deep Opening under Biaxial In Situ Stresses
Publisher: ASCE
Abstract: This paper presents a generic analytical solution for stresses and displacements developed around an arbitrarily shaped underground opening excavated in an elastic soil/rock mass with biaxial in situ stresses. A series of ...
Undrained Spherical Cavity Expansion in Unsaturated Soils: Semianalytical Solution Coupling Hydraulic and Mechanical Behaviors
Publisher: ASCE
Abstract: A coupled hydromechanical solution to undrained spherical cavity expansion problem in unsaturated soil is proposed with an elastoplastic model for unsaturated soil. The mechanical response and hydraulic behavior of soil ...
Analytical Solution to Cylindrical Cavity Expansion in Mohr–Coulomb Soils Subject to Biaxial Stress Condition
Publisher: ASCE
Abstract: In this paper, a semianalytical approach is presented to formulate an excavated cavity in Mohr–Coulomb soils subject to biaxial initial stresses. The response of cavity expansion within the plastic region was investigated ...
Investigation of the Load–Settlement Response of Piles in Sand Using an Interface Constitutive Model
Publisher: ASCE
Abstract: A semianalytical approach has been developed to investigate the nonlinear load–settlement behavior of bored single piles and pile groups embedded in sands. A more rigorous load-transfer function for the pile shaft, adopted ...
Effect of Soil Structure on Penetration Response of Jacked Piles: Model Tests in Structured Clays
Publisher: American Society of Civil Engineers
Abstract: Laboratory model tests were conducted on artificially structured clays using self-developed equipment to better understand the penetration mechanism of jacked piles in structured clays. Two artificially structured clays ...
