初始应力对水闸混凝土加固的影响研究

Study on impacts from initial stresses on concrete strengthening for sluice

结合淮安地区某老水闸的加固工程,通过有限元分析水闸加固前后的应力应变状态,研究初始应力对加固结构的影响,得出考虑老结构的初始应力所得的计算结果偏于安全,成果可为病险水闸加固工程提供较好的参考。

In accordance with the strengthening project of an old sluice in Huai＇ an District, the impacts from the initial stresses on the strengthened structures are studied herein through the analysis made on the stress-strain state before and after the strength- ening of the sluice and then the calculation result obtained under the consideration of the initial stresses of the old structures is partial to safety, which can provide a better reference for the defective and dangerous sluice concerned.
