Monitoring and analysis of soft foundation pit with braced structure of bored cast-in-place pile

2011 International Conference on Electrical and Control Engineering, 2011
The project is located in Changning District in Shanghai which is surrounded by lots of buildings. On the condition of silt clay, the retaining structure of foundation excavation is bored cast-in-place pile with interior bracing. The building settlement is related to the distance to foundation pit, the type of foundation, the soil parameter in ...

Field study on post-grouting effects of cast-in-place bored piles in extra-thick fine sand layers

Acta Geotechnica, 2018
The post-pressure grouting technique has proven to be an effective method to enhance axial resistance. In this paper, field tests were conducted to investigate the performances of large-diameter cast-in-place bored piles for six combined side-and-tip grouting piles and two side-grouting piles in extra-thick fine sand layers.

Monitoring and analysis of cast-in-place concrete bored piles adjacent to deep excavation by using BOTDA sensing technology

Journal of Modern Optics, 2019
ABSTRACTIn order to monitor the deflection of bored piles, BOTDA sensing technology is employed to measure the strain and temperature profiles along three bored piles adjacent to a deep excavation. Based on the measured strain, the deflections can be calculated according to the mechanics of materials.

Applicability evaluation of cast-in-place bored pile in permafrost regions based on a temperature-tracking concrete hydration model

Applied Thermal Engineering, 2019
Abstract In recent years, cast-in-place bored piles have been widely used in engineering constructions. However, the applicability of bored pile was constricted by the loss of concrete strength in the cold curing environment of permafrost. A temperature-tracking concrete hydration model was developed to clarify the refreezing process of the bored ...

Evaluating the Competitiveness of the Methods of Bored Cast-in-Place Piles Underreaming when Constructing the Foundations of Multistorey Buildings

Modern Trends in Construction, Urban and Territorial Planning
Introduction. The bored сast-in-place piles are the type of piles most adjusted to specifics of the multistorey building construction. The article studies the existing methods of underreaming such piles as the main tool to minimise their diameter, length, and quantity, thus optimise and reduce the cost of foundation design and its subsequent ...
