摘要
钢筋应力计是桩身内力测量的主要工具和手段,桩身内力测量是桩基试验的重要内容,但在实际工程中,由于各种复杂因素导致测量结果往往并不理想,列举了可能产生误差的因素,并通过消除引入物理常量、估测孔径和正确精心设置应力计位置等,对试验结果的误差进行分析和适当修正,最终得出客观的较为准确的桩身内力图。
The internal stress measurement of pile body is the key of pile foundation test. In practical engineering,due to various complicated factors,the measurement result is not ideal,and the factors that may cause error were enumerated,Through the elimination of the introduction of physical constants,determination of filling factor,and calibration of the exact position of the reinforcement,the error of the test results was analyzed and and appropriatly amendmented,objective more accurate pile internal force diagram was obtained finally.
