| 摘 要： | 利用国内外关于地应力的实测资料,通过数值方法探讨我国岩体的重要力学参数——弹性模量沿地层埋深的变化规律：10km埋深以上基本是线性增加的,在10km埋深附近会急剧减小.以丹江口地区为例,依据其表层地应力和岩体弹性模量的试验数据,利用我国岩体弹性模量沿地层埋深的变化规律,反演该区几种主要岩石在不同埋深处的弹性模量.

| Abstract: | The changing rules along stratigraphic depth of young modulus of rock body in our country is explored by numerical simulation method,according to the mapping ground stress information in domestic and abroad： basically linear increasing above the depth 10km,and a sharp decreasing near depth 10km.To Danjiang Kou regional for example,the young modulus of several main rock body in different depth was derived,adopting the changing rules of young modulus of rock body in our country along stratigraphic depth and the surface ground stress measured and the test data of rock body young modulus in Danjiang Kou area. |
