| 摘 要： | 一般认为地应力的形成主要与地球的各种动力运动有关，且构造应力场与重力场是地应力的主要组成部分。以某黄金矿山为例，以地球物理学的基本观点及地球重力场理论为指导，得出重力所致竖向地应力和水平地应力的表达式；认为地下应力产生的最根本原因在于重力(地心引力)，重力不仅可以产生竖向地应力，而且还可以产生水平地应力。计算证明黄金矿山(地下工程)水平地应力远大于竖向地应力。地壳内黄金矿山采掘巷道所受的各种压力均来源于地心对岩土(石)的引力。 |

| Abstract: | Generally speaking, the forming of crustal stress mainly related to the different dynamic actions, and the tectonic stress field and gravity field are the main component part of the crustal stress. Taking a gold mine for example, according to the basic theories of geophysical and the earth gravity field, the express equation of the vertical crustal stress and the horizontal crustal stress that caused by gravity was point out. The primary reasons for causing the crustal stress in gold mine is the gravity(the terrestrial gravity). The gravity not only can result in vertical crustal stress, but also result in the horizontal crustal stress. By the calculation, it was proved that the horizontal crustal stress was far stronger than the vertical crustal stress in gold mine(underground tennel). In the crust, all the presses in the digging gallery of a gold mine come from the gravity. |
