预制桩极限承载力的实测分析

THE MEASUREMENT ANALYSIS OF LOAD-BEARING CAPACITY IN DRIVING PREFABRICATED PILES

本文通过对预制桩打桩监测，介绍一种精确纪录锤桩撞击瞬时历程，进而分析确定单桩极限承载力的测试方法，并根据测试分析结果，对提高桩基础的技术经济效益和施工质量进行讨论。

n this paper,through the measurement of driving the prefabricated piles,a testing method is introduced by recording the instantaneous process of hammer-pile impact accurately and then,by analysing and predicting the load-bearing capacity of the pile. According to the results of the measurement,a discussion is made on improving economic benefits and construction quality of the pile foundations.
