| 8. | Based on analysis of geologic foundation record about pingzhuang basin , a lot of sino - foreign geothermal geology record and investigation of field geology , measuring of ground temperature in person and geo - chemical analysis of ascension spring , gushing water of fault , the fact that the anomaly of geothermal gradient of pingzhuang basin , which is in region of low geothermal gradient , is caused by redistribution of conduction - oriented geothermal heat flow which is result from upheaval and depression of basin foundation bed is pointed out . after the field of ground temperature is simulated under the background of conduction - oriented geothermal heat flow by means of ansys , the characteristic of ground temperature distribution of top surface of basin foundation bed ( yixian team ) is revealed . the sound condition of transmissibility fault and feeding water source , which are imperative in formation of the low - medium temperature geothermal system of convective type , is possessed in pingzhuang basin 通过对平庄盆地基础地质资料、国内外大量地热地质资料的分析和野外地质调查、矿井实测地温以及上升泉、断层涌水的地球化学分析等工作基础上,指出地处低地温梯度背景区的平庄盆地地温梯度异常是由于盆地基底隆起和坳陷引起传导型大地热流再分配所致;运用州sys数值模拟了大地热流向地表传导背景下的盆地地温场,从而揭示了盆地基底(义县组)顶界面地温分布特征;阐明了盆地具有形成中低温对流型地热系统所必需的导水断裂、补给水源等的良好条件,中低温对流型地热系统是地热勘查的主要对象;圈定了平庄盆地北部朝阳沟?骆驼营子地热勘查远景区。 |
| 9. | Through the analysis we found that the effect will become more obviously with the increase of thickness or width of superstratum and the decrease of the coefficient of foundation bed ; ( 3 ) anisotropy and nonlinear elastic f . e . m . model has been established and the effect of stress dispersion in compound two - layer foundation was analyzed on the base of the model . from the analysis we can conclude that the coefficient of subsidiary stress dispersion will amplify with the increase of thickness or width or stiffness of back - up coat ; ( 4 ) the formula which can be used in conventional calculation has been deduced for calculating the coefficient of subsidiary stress dispersion and it also has been affirmed to be reasonable through the checking calculation ; the whole theory of compound two - layer foundation has been brought forward in this paper and it ' ll enrich the theory of composite foundation 针对以上问题本文做了以下一些工作并得到若干结论: ( 1 )提出了“复合双层地基”的概念,并通过工程实例证明此概念的提出有其合理性和必要性; ( 2 )用弹性地基梁理论证实了复合双层地基确有应力扩散效应,且扩散效应随上覆硬层厚度、刚度的增加而增大,随下卧层基床系数的增大而减小; ( 3 )建立了非线弹性、各向异性有限元模型,并以此为基础分析了复合双层地基的应力扩散效应,得到附加应力系数随加固层厚度、宽度、刚度的增加而增大的结论; ( 4 )推导了可用于常规计算的复合双层地基应力扩散系数公式,并代入工程实例进行了验证。 |
