ABSTRACT In order to study the thermally activated characteristics of plastic deformation and the effect of alloying element on the thermal activation of structural steels, the properties of plastic deformation for 20g and 13Ni3CrMoV steels have been examined in the temperature of 77—473K and strain rate of 〓. The experimental phenomena show that the effective stress of plastic deformation decreases with the increase of alloying elements content (namely solute solution softening) and the frequency factor deceases with the increase of effective stress.

The result shows: the material of glass reinforced plastic mortar pipe is brittle, the enlaced sample always destroyed along the interface of different layers, but the centrifugal sample destroyed along a breach; the capacity of bearing radial load of enlaced glass reinforced plastic mortar pipe is better than the centrifugal ones, the destroyed forms of them is also different. Secondly, the whole pipe and direct shear friction experiments between glass reinforced plastic mortar pipe and typical soil of Shanghai have been done.

结果表明：玻璃钢夹砂顶管管材属于脆性材料，缠绕式玻璃钢夹砂顶管的材质试样基本沿着层与层之间的分界面破坏，而离心浇铸式玻璃钢夹砂顶管材质试样的破坏是沿着某个滑裂面破坏；缠绕式玻璃钢夹砂顶管的抗径向荷载性能要优于离心浇铸式玻璃钢夹砂顶管，同时两者在径向荷载作用下的破坏形式明显不同。

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.
