工字钢桩在天津滨海地区排水管道基坑支护中的应用

Application of HP Piles in the Drainage Pipe Construction Excavation Supports

结合天津滨海地区某排水管道基坑工程,运用有限元计算软件plaxis模拟工字钢桩支护的施工开挖过程,分析基坑的稳定性、支护结构与土体应力、应变的分布特点,指出工字钢桩应用时应注意的问题。

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 ana lyzed.
