THE PILE DRIVING PRESSURE AND THE ULTIMATE BEARING CAPACITY OF PILE DRIVING BY STATIC FORCE
-
摘要: 通过两个工程及266根不同桩径、不同桩长, 采用静力法沉桩的压桩力与极限承载力的对比分析, 探讨静力法沉桩中, 位于不同持力层中桩的终压力与极限承载力的关系及桩的恢复力与入土深度的关系, 并提出估算沉桩阻力的近似方法, 其结果将为静压桩设计及施工提供有益的参考。Abstract: Based on two projects and two hundred and sixty six static pressed piles with different section and different length,the relationship between the final driving force and the ultimate bearing capacity of pile and that between the recovering pressure and the driving depth of pile are discussed.Also, an approximation to estimating the pile driving resistance is put forward.
