Analysis of the influence of pile embedded cap depth on horizontal bearing capacity of PHC pipe pile group with cap

Abstract

This paper is based on the background of the field experiment of the closed renovation project of the coal yard of Shanxi Zhangshan Power Generation Co., Ltd., and the horizontal bearing capacity experiment of the three-pile cap foundation of the in-line PHC pipe piles to be carried out on the site is used as the prototype. ABAQUS establishes an analysis model to analyze the influence of pile embedded cap depth on the horizontal bearing capacity of pile cap foundation. The results show that the maximum bending moment the pile can withstand increases as the depth of the pile embedded cap increases. Therefore, increasing the depth of the embedded cap can increase the horizontal bearing capacity of the three-pill.
