Purpose In the pile-soil interaction system, the disturbed soil directly affects the safety of the
laterally loaded pile. The soil displacement field helps to evaluate the range and degree of …

This paper presents and discusses the measured responses of single and grouped helical
piles to strong ground motions during a large-scale shake table testing program. The effects …

This paper presents full-scale field tests of grouted steel pipe micropile embedded in marine
soft clay under compressive and tensile loads. The load-displacement responses, axial …

Screw micro-piles are becoming progressively popular for inherent advantages and
installation convenience. Their load-transfer technique and failure mechanism are complex …

Screw piles have been widely used as foundations for various types of structures. Drilling
velocity ratio, the ratio of rotational velocity to driven velocity, is a critical parameter that …

Steel screw piles may be a viable pile foundation type in the permafrost region of the
Canadian Arctic but the effects of climate change may accelerate the creep settlement rate of …

A screw micropile consists of a smooth shaft at the top, threaded shaft at the middle, and
tapered shaft at the bottom. Research is required to investigate the axial behavior and …

A number of buildings in the Canadian Arctic communities have failed or showed signs of
failure of pile foundations caused by climate-change-induced excessive settlements. Effects …

Research on the performance of continuous-flight piles for the use in permafrost is rare. In
the present laboratory research, continuous-flight pile segments with 89 mm diameter and …

Because of the scarcity of land for urbanization, multistoried construction projects are
becoming a preferred choice. Such projects more often require soil reinforcement or ground …
