Abstract: This paper presents a case study of the application of HP piles in the excavation support of drainage pipe construction in the coastal area of Tianjin City. The progress of the excavation was simulated with the finite element software Plaxis. The stability of the deep excavation as well stress and strain distributions within the supporting structures and soil mass are analyzed.
