Abstract For the design of a deep foundation, piles are presumed to transfer axial and lateral loads into ground. However, effects combined generally ignored in engineering practice since there uncertainties precise definition soil–pile interactions. Hence, for technical discussions interactions due dynamic loads, three-dimensional finite element model was developed evaluate soil pile performan...

In the recent years, non-connected piled raft foundation has been considered as an economical and practical deep foundation in the situation that high shear and concentrated loads may occur at the connection of the raft and pile head. This paper was presented an experimental study of a square foundation on the effects of parameters such as S/D, L/D and etc. in two cases of connected or non-conn...

In order to guarantee perpendicularity of rotary cast-in-place pile in Karst areas, filling, like sand, etc., is commonly used between the inner steel casing and outer sleeve; while sleeve pulled out or a vertical load applied on top pile, sand will move, contact, push against each other, which leads recrushing; therefore, shear characteristics secondary breakage are meaningful problem study wi...

Retrofitting works are immensely essential for deteriorated and damaged structures in Engineering and Medical fields, in order to keep, or return to, the originality for safe guarding the structures and consumers. In this paper, different types of methods of retrofitting review notes are given based on the experimental, numerical and analytical methods results on strengthening the Reinforced ce...

The construction of offshore wind power pile foundations on artificial islands is a challenging task due to soil consolidation and additional loads that result in negative skin friction (NSF). In this study, comprehensive pile–soil interaction model established investigate the development NSF under action self-weight fill surcharge load. one-dimensional theory an ideal elastoplastic load transf...

in soft soil areas, equal-length piles are often adopted in the retaining system. a decrease in the bending moment value borne by the retaining structure along the pile depth (below the excavation bottom), leads to an inadequate use of the pile bending capacity near the pile bottom. this paper presents retaining systems with long and short pile combinations, in which the long piles ensure integ...

The underground energy geostructure represented by the pile is one of key paths for cooperative development space and geothermal energy. Because its advantages low cost, high efficiency no extra occupation space, it has become a feasible alternative to borehole heat exchanger. change in temperature field surrounding ground not only affects geological environment but also influences thermomechan...

Pile foundation systems are used in India many projects such as metro and railways, flyovers, multi-story buildings. The pile transfers superstructure load to the substructure, i.e. rock layers by means of skin resistance end-bearing resistance. In this study, an attempt is made observe performance socketed piles soft rock. A series small-scale model laboratory studies have been conducted using...
