| 摘 要： | 通过在混凝土中直接埋设应力计和在量测区包裹橡皮泥后埋设应力计的对比试验,研究了振弦式钢筋应力计的侧限条件对混凝土应力测量结果的影响.试验结果表明:基于各截面上混凝土与应力计量测区钢筒的应变一致假定,振弦式应力计能较准确地测量混凝土的应力,但其测量值偏小；采用橡皮泥包裹应力计量测区的柔性侧向约束条件与应力计标定时的自由边...

| Abstract: | Through the comparison tests of embedding vibrating string stress meter in concrete,which is wrapped with and without plasticine at the measuring area,the confine conditions' influence on the outcomes of the stress meter was studied when it's measuring the stress of concrete.The results showed that: based on the assumption that on any cross section the strain of concrete and stress meter are the same,vibrating string stress meter can relatively accurately measure the stress of concrete,but the measured valu... |
