深基坑围护桩最大间距分析

ANALYSIS ON MAXIMUM SPACING OF ENCLOSING PILE OF DEEP FOUNDATION PIT

排桩式结构是目前基坑支护工程中应用最广泛的形式,合理选取桩距可节省支护工程造价。引用土拱概念分析基坑排桩支护结构,提出的悬臂式排桩支护结构桩净距的计算公式,通过工程实例进行验算,证明比较合理。

Rowed pile structure is most widely adopted in the supporting work of foundation pit currently and reasonable pile spacing can save the costs of the supporting work. Soil arch conception is introduced to the analysis of the rowed pile supporting structure, and a formula established for calculating the net space of the cantilever rowed pile structure. Engineering calculation case has proven its rationality.
