Compression Deformation and Settlement Analysis of Bored Pile Foundation of Super High-rise Building
In order to improve the safety of pile foundations in super high-rise buildings,this article takes a certain high-rise building as an example and uses experimental testing methods to analyze the compression deformation and settlement of drilled pile foundations in super high-rise buildings.The results show that the integrity of the bored pile body is good,with a compressive strength of 56.8 kPa and a wave velocity of 4 420-4 550 m/s,meeting the quality requirements of the design scheme;The Q-s curves of the test piles and engineering piles are both in a slowly changing form and have not reached the limit state.The variation in settlement of all types of piles is relatively small;The average lat-eral resistance range of test piles and engineering piles is110.4-121.3 kPa.The research results can provide reference for the rational design and construction process determination of drilled pile foundations in super high-rise buildings.
