在用试验 meaning in English

in-service testing

With the development of high faced rockfill dams , more attention is being paid to the rheology deformation characteristics of the dam body . for the importance of determing rheological parameters and with a fairly difficult in the rheological characteristics of faced rockfill dams , in this paper aims to solve some rheology deformation problems concerning rheological characteristics of faced rockfill dams in practice engineering by developing experimental methods , perfecting theoretical analysis and improving numerical simulation
在对面板堆石坝流变特性研究这一领域中，确定流变参数既重要又具有一定的难度，因此，本文的主要研究工作力求在用试验方法求流变参数上有所发展，在理论分析上有所完善，在数值模拟方法上有所改进，期望能在实际工程中解决面板堆石坝出现的一些关于流变变形问题。
