A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.

本文主要在气液两相流作用条件下，通过室内自制装置，对管材钢J55做了系列冲刷-腐蚀试验，结果表明，气液两相流对钢管内表面冲刷－腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀，生成腐蚀产物，同时钢管金属表面不断被具有高流速的气液相交替地冲击，不断地从金属表面脱去保护膜或腐蚀产物，裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后，再被两相流冲掉，如此反复，造成管内金属表面膜的连续破坏，使腐蚀加剧，最终导致钢铁表面的冲刷腐蚀失效。

Comparison results show that heat pipe work is not continuous but fluctuant in one work cycle about five months,its actual working time is two-thirds of one work cycle,the cooling effect of heat pipe subgrade in winter is obvious,which is good for the contained cool increase of soil body and improves subgrade heat stabilization,there is a decrease for its cooling strength with the increase of horizontal distance,its effective operating radius is 2.25 m,its maximum cooling strength is in evaporation segment in depth direction,which low the thaw sensitivity of permafrost in the seasonal thaw layer about permafrost table.

研究发现，热棒在约为5个月的工作周期内并非连续工作而呈波动式，实际工作时间为工作周期的2/3；热棒路基冬季降温效果明显，有利于路基土体冷储量增加，提高路基热稳定性；热棒在路基中的降温强度，水平方向随距离增大而衰减，有效作用半径为2.25 m，深度方向在热棒蒸发段最大，降低上限附近季节融化层冻土热融敏感性。
