浅谈人工挖孔桩设计、施工中的若干问题

Issues on the Design and Construction of Concrete Piles with Man-made Hole

人工挖孔桩具有受力明确、承载力高、持力层检查直观、桩身质量有保证、施工方便、无噪音、更适于狭窄场地上施工、造价低等优点。近年来,人工挖孔桩在湖北省武汉市尤其洪山区的多、高层建筑中得到广泛应用。根据国家相关的规程及规范,从挖孔桩的特点、设计计算、构造要求、施工要点等方面进行了较详细的论述。

The concrete piles with man-made hole have characters of definite load conditions, high bearing capacity, simple construction, no noise and low expenses, etc. It has been widely used in multi-story and high-rise buildings in Wuhan, especially in Hongshan district in recent years. Based on the national standards, this paper discusses the characters, designing calculation and construction of those piles.
