Experimental investigations of bearing capacity of bored-cast-in-place tapered piles
Soil Mechanics and Foundation Engineering, 19901. The investigated types of bored-cast-in-place tapered piles with a taper angle of 1°20′, 2°, and 2°40′ have a specific bearing capacity which exceeds by 20–30% the specific bearing capacity of cylindrical piles having the same length.

The bearing capacity property of large-diameter bored cast-in-situ deep and post-grouting pile is analyzed on the basis of measuring data of static load test and axial stress measure data. The study indicates that the large-diameter bored cast-in-situ deep and post-grouting pile show the characteristics of the friction when the bearing course at pile ...

Field study on post-grouting effects of cast-in-place bored piles in extra-thick fine sand layers
Acta Geotechnica, 2018The 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.

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.

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 ...
