亿万年来,地球经历了多次大的地质构造活动,造成了地壳应力状态的复杂性和多样性。人类进行采矿等工程活动,就要研究地壳应力活动特征及其规律性,地应力测量就是这一工作的基础。 地应力,也称原岩应力,是指岩体在天然状态下所具有的内在应力,包括由上覆岩体重力所 For hundreds of millions of years, the Earth has undergone many major geological tectonic activities, resulting in the complexity and diversity of crustal stress states. For mankind, mining and other engineering activities, it is necessary to study the crustal stress activity characteristics and regularity, geostress measurement is the basis of this work. Geostress, also known as the original rock stress, refers to the inherent stress of the rock mass in its natural state, including the overburden gravity
