超长输水隧洞衬砌混凝土测强曲线的建立与应用

Establishment and application of strength test curve about ultra-long water tunnel with lining concrete

本文通过对大伙房水库输水工程D&B1,D&B2标段衬砌混凝土强度数据分析,建立了针对本工程的两种测强曲线方程。该曲线方程应用到工程中,可以便捷、准确、无损坏地测得衬砌混凝土的实际强度,为工程施工提供准确的数据依据,对于评定衬砌构造物的混凝土质量起到重要作用。

In this paper,based on the data analysis of the strength of concrete lining section D&B1 and D&B2 in Dahuofang Reservoir water transfer project,it has established two strength test curves.These equations can be applied and can conveniently and correctly test the natural strength of concrete lining section without damage.On the basis of these equations the accurate data for the construction can be provided.The curve also plays an important role in quality assessment of the concrete in lining structures.
