Recently a number of researches about mechanical splice have been studied to apply with a large diameter reinforcing bars of spliced sleeves. In this study the structural performance of large diameter reinforcing bars with spliced sleeves in low temperature was evaluated. For the application of nuclear power plant structures, two different types of existing splices with #11, 14 rebars were fabricated and static and dynamic test were performed on the basis of ASME SEC III DIV.2 CC-4330.

The temperature of subsea pipeline, approximately as high as 100℃, is significantly higher than the temperature of surrounding sea water and sediment. In this reason, heat can be lost from the subsea pipeline to cause serious operation problem. Therefore it is important that the subsea pipeline must be designed to ensure that heat loss is small enough. Heat loss of unburied pipeline is higher than buried pipeline. For that purpose, trenching and backfilling system is a commonly used method for maintaining flow assurance in subsea pipeline installation. For this commonly used method, knowing thermal conductivity of backfill is essential to protect a heat loss of pipeline. This paper presents thermal conductivity of backfill soil using laboratory model test and numerical analysis for various backfill. In conclusion, it can be seen that higher the sand content of the man-made backfill sample, the higher the thermal conductivity. On the other hand, as the water content increases, the thermal conductivity becomes smaller.
