既有钢筋混凝土构件中实际内力是反映结构安全状况的重要指标之一。但是在工程建设和使用过程中,结构中实际内力与按理想数值模型计算所得内力有一定的差距。在前文应力释放技术测试构件内力基本理论推导的基础上,介绍了开槽法识别钢筋混凝土构件内力的试验研究方法。试验结果与数值模拟结果吻合,证明了采用应力释放技术测试在役钢筋混凝土构件的内力值是可行的。
既有鋼觔混凝土構件中實際內力是反映結構安全狀況的重要指標之一。但是在工程建設和使用過程中,結構中實際內力與按理想數值模型計算所得內力有一定的差距。在前文應力釋放技術測試構件內力基本理論推導的基礎上,介紹瞭開槽法識彆鋼觔混凝土構件內力的試驗研究方法。試驗結果與數值模擬結果吻閤,證明瞭採用應力釋放技術測試在役鋼觔混凝土構件的內力值是可行的。

The working internal force of existing reinforced concrete members is one of the important indexes reflecting the safety condition of the structures.However,the actual internal force,during the construction and occupation,has certain distinction from the one calculated by the ideal numerical model.This paper intro-duces the experimental research on the internal forces identification of reinforced concrete members by grooving method,based on the basic theory of the internal forces measurement by stress-release method presented in the previous paper (I).The test results have a good accordance with the numerical simulation,which proves that internal forces measurement in working reinforced concrete members by stress-release method is feasible.
