英文摘要	Structural damages due to frost jacking of a foundation depend on the adfreeze bond between the freezing soil and the structure. To reduce the adfreeze bond strength between the foundation surface and the frozen ground, a fiberglass reinforced plastic (FRP) cover was proposed for foundations along the Qinghai-Tibetan transmission line. Direct shear tests were carried out in the laboratory to assess the adfreeze strength between a frozen soil and FRP covers as well as concrete plates under varying conditions. The results show that the cohesive component of the adfreeze bond strength is controlled by the moisture content and temperature of the frozen soil. The frictional component has only a weak correlation with temperature, but is significantly affected by the moisture content. The FRP cover can significantly reduce the cohesive component of the bond strength but shows little effect on the frictional component. The tests further show that the FRP cover can also reduce both, the adfreeze bond strength and bond healing, especially for low-temperatures. The results indicate that a smooth FRP cover can be effective in reducing the adfreeze bond strength between a foundation and the frozen soil. Therefore, this new material is considered a powerful alternative for reducing damages caused by frost heave in cold regions. (C) 2016 Elsevier B.V. All rights reserved.
