林区桥梁测强曲线的编制

ESTABLISHMENT OF STRENGTH TEST CURVE ABOUT FOREST BRIDGE

为解决林区桥梁结构砼强度现场检测精度问题．按林区各地区常用原材料、配合比和工艺条件制备试块，并对其进行了回弹法、超声法试验研究，利用数理统计方法确立相关数学关系式Ｒ＝ｆ（Ｎ，Ｌ）、Ｒ＝ｆ（Ｖ，Ｎ），建立了林区桥梁测强曲线。

To solve the problem about the precision of concrete strength test in forest bridge. we made test examples under the definite conditions and tested and researched them by the methods of the rebound and synthesization. We used the method of maths and statistics to establish the relative formulae: R=f(N, L).R=f(N. V), and establish the strength test curve about forest bridge.
