大湖口大桥基桩承载力试验与完整性检测的综合分析

Comprehensive Analysis of the Load and Integrity Tests of Pile in Dahukou Bridge

通过对大湖口大桥基桩承载力试验与完整性检测成果的综合分析,探讨地层实测摩阻力与工程地质勘测推荐的极限摩阻力的相差较大的原因,提出了试验桩完整性对地层实测摩阻力值的准确性有重要影响的观点,并对各地层极限摩阻力的取值提出了建议。

The author makes comprehensive analysis of load-bearing capacity and integrity test of pile in Dahukou bridge, researches the difference of the ultimate friction of actual measurement between testing pile and engineering geology investigation, probes the importance of pile integrity for the clay friction (testing) and proposes a method of determing the ultimate friction of stratum in this bridge pile.
