Abstract

Abstract

Based on static load tests and rock foundation load tests conducted on four large-diameter rock-socketed piles in a Chongqing project, the influence of construction quality on the vertical compressive bearing capacity of rock-socketed piles in soft rock was discussed. The results indicated that the vertical compressive bearing capacity of rock-socketed piles was greatly affected by both the construction quality of pile foundation and the sediment thickness at the pile base. Based on design standards, if the vertical compressive bearing capacity of the embedded rock section of rock-socketed piles in soft rock needs to be significantly increased through experimental verification, the construction quality and acceptance criteria for the pile foundation must be clearly specified.
