The Behavior of Pile Group Under Inclined Static Load With Different Angle of Inclination in Sandy Soil

Abstract

Pile is the form of deep foundation some time may be applying as a condition of inclined loading. There are limited experimental studies in existence on the performance of vertical piles exposed to inclined loads. In this paper, a static inclined load with four angles applied load varying (i.e., 0,15, 30, and 45 degrees) from the horizontal axis of the pile are used to the comparison of behavior for pile group as a three configurations 2x2, 2x3, and 3x2 in sandy soil. The experimental works include a soil tank and several of tools used to achieve the objective of this study. It can be seen that the pile group is influenced by the angle of inclination of applying load, furthermore the results displays that the increase in spacing between pile cause decrease lateral movement under the similar angle of inclination of load applied. The performing of each models better-quality using S/D=7, this is attributable to reduce the interface of pile-soil-pile for the group. Groups 2x3 showing resistance and have bearing capacity to the lateral displacement from other groups about 40% for group 2x2 and about 50% for group 3x2

Application of Internet of Things Technology in the Construction of Bored Pile Foundation in a High Altitude Environment

“…On the other hand, concrete is a material with poor thermal conductivity, under the action of cement hydration heat, the highest temperature rise often occurs in the center of the pile concrete, after the concrete is poured, the surface concrete in contact with the permafrost immediately inputs heat to the permafrost, which reduces its own temperature rapidly, which is likely to cause the temperature difference between the surface and the center of the pile foundation concrete to be too large, resulting in the formation of temperature cracks. At the same time, if the temperature of the concrete at the interface drops below 0 °C in the plastic state, the water in the concrete pores will freeze and the ice crystals will expand and cause the pore structure to coarsen and deteriorate; it will also affect the durability of bored pile concrete [2]. e bored cast-in-place piles are buried in the frozen soil, which is a hidden project and is difficult to maintain; the concrete strength of the pile body is insufficient or the pores are deteriorated, this will leave the pile body with permanent and difficult to remove hazards, resulting in insufficient bearing capacity of the pile foundation, excessive settlement, and ultimately jeopardizing the safe operation of the bridge.…”

Study of The Axial and Lateral Bearing Capacity of Bored Piles Affected by Liquefaction

“…According to Daher and Abbas (2021), when the axial load applied to a pile is increased, there is an associated increase in the lateral displacement of the pile head. This result indicates a decrease in the lateral bearing capacity of the pile [10].…”

Study on the Bearing Capacity of High‐Cap Inclined Pile Foundations

“…Increasing the pile spacing and pile diameter will increase the construction cost of the cap, and improvement of the horizontal bearing capacity of the foundation is limited by the pile diameter and pile spacing. To explore a more economical and e ective method for improving the horizontal bearing capacity of pile foundations, scholars worldwide have proposed setting inclined piles in pile group foundations to improve their horizontal bearing capacity [5,6].…”
