| 摘 要： | 通过简要介绍火山区不同压力源模型引起的垂直形变与水平形变特征,总结不同模型引起的最大水平位移与最大垂直位移的比值R,得到膨胀模型产生的地表形变多以中心为对称,R小于0.5;腔状模型产生的地表形变多为轴对称,可得到更高的R比值;这些结论为模拟分析火山区压力源参数选用模型时提供依据.最后利用所得结果,分析了长白山天池火山可...

| Abstract: | The characteristics of the vertical and horizontal deformation caused by different pressure source models are introduced.Then the ratio R for different models of maximum horizontal to maximum vertical displacement is summarized.The results show the surface deformations of the dilatational models are centrosymmetric and R is less than 0.5;However the surface deformations of the cavity models are axisymmetric and R is larger.The conclusions provide the basis for choosing appropriate models when we simulate th... |
