The results show that at sea level, coolant flow rate affects the plug pressure, heat flux and temperature; at design operating condition, coolant flow rate has no effect on pressure and heat flux on the plug wall. With the same coolant flow rate, plug temperature at sea level is higher than that at design operating condition; under the same operating condition, ramp temperature is higher than the plug base temperature.

Based on the analysis of the factors caused land subsidence, the internal mechanism and development process of land subsidence caused by two mainly factors of dewatering and underground mining have been studyed in this thesis. The random medium model and methods have been established to calculate the land subsidence and deformation caused by dewatering or underground minging and both of them. The prediction problem of land subsidence and deformation caused by single factor and many factors has been solved.

For each strategy, a corresponding exploitation plan of groundwater was designed. Then each designed exploitation plan (except scheme 3) was put into the model for calculation and simulation. The analysis on the forecasting results every plan indicates that:(1) Shuting down the self-provided wells is the most direct and effective method, playing an important role in the land subsidence prevention.(2) The resumption of compressed soil by groundwater artificial recharge is limited. So the artificial recharge can\'t provide essential effect for the resumption of land subsidence, unless the artificial recharge is much more than the groundwater withdrawal.(3) The method of "adjusting the exploitation stratum of groundwater to the shallow" has an obvious effect on the land subsidence prevention.(4)"Sand wells" can increase the leakage recharge for confined aquifer, and thus can slow and prevent the development of the land subsidence.(5) For the groundwater exploitation in Xi\'an, emergency self-provided wells should be managed according to the well spacing of 1600m, 2000m and 1600m, respectively, in the river terrace area, alluvial-proluvial fan area and loess tableland area to exploit the first confined groundwater. Corresponding individual well yield can be set as 2500m~3/d, 1500 m~3/d and 200 m~3/d. Make emergency self-provided wells pump in the dry year and stop pumping groundwater to restore and conserve underground water sources in average years and wet years. In this way, groundwater withdrawal of 162000m~3/d can be obtained to provide for the supplement of water supply in Xi\'an. As a result, the water supply stress can be released in dry years. The groundwater depression formed in the exploiting year can resume in 3-4 years. At the same time, this exploitation manner will not lead to obvious land subsidence.
