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

Journal of Control Science and Engineering, 2022
In order to solve the problem that the current geophysical method is difficult to locate in the mud of bored piles, the problem of effective exploration of karst caves at the bottom of piles, the author puts forward the application of Internet of Things ...

Investigation into the effect of uncertainty of CPT-based soil type estimation on the accuracy of CPT-based pile bearing capacity analysis [PDF]

, 2016
Cone Penetration Test (CPT or CPTu) is commonly used for estimating soil types and also for the geotechnical design of pile foundation. However, the level of agreement between the CPT-based soil types and the traditional identification of soil types ...

Analysis of a rapid load test on an instrumented bored pile in clay [PDF]

, 2006
Rapid load testing methods for piled foundations are generally easier and quicker to mobilise than classic static tests, and are less complex to analyse than dynamic load tests.

Risk Management of Bored Piling Construction on Sandy Soils with Real-Time Cost Control

Infrastructures, 2021
In a global society, in which geotechnical projects are increasingly designed in a country other than the one where construction takes place, geotechnical risk management must be extended to cover infrastructure works, which are smaller than dams and ...

Stability Investigation of Contiguous Replacement Piles.

Zanco Journal of Pure and Applied Sciences, 2023
Urbanization leads to increase lands cost which resulted in the construction of high towering vertically toward the sky and use underground for construction. Foundations of these structures need deep excavation. Anti-slide piles are a suitable option for

Numerical investigation into the failure of a micropile retaining wall [PDF]

, 2017
The paper presents a numerical investigation on the failure of a micropile wall that collapsed while excavating the adjacent ground. The main objectives are: to estimate the strength parameters of the ground; to perform a sensitivity analysis on the back

Study on Disturbance Mechanism of Squeezed and Non-Squeezed Soil Piles on Soft Soil Foundation

Applied Sciences, 2023
The construction process of pile foundations can significantly disrupt the soil. Therefore, it is necessary to limit the degree of soil disturbance caused by pile foundation construction to an acceptable level. This paper examines the disturbance effects

CHD pile performance, Part I:Physical modelling [PDF]

, 2016
The Continuous Helical Displacement (CHD) pile is an auger displacement pile developed by Roger Bullivant Ltd in the UK. It has performance characteristics of both displacement and non-displacement piles due to the nature in which it is installed.
