地质体裂隙等间距性的理论研究

为了预测断裂可能发生的空间位置及其规律,断裂等间距性即要模拟材料的弹性性质又要模拟材料的断裂性质,决定了建立其定量理论的复杂性。对断裂等间距性进行了初步理论研究,采用非欧模型,建立断裂等间距的一维理论模型,通过对模型的求解,给出一维条件下应变不协调张量有解条件及相应单轴拉伸条件下的应力分布规律,并对方程中拟和系数影响进行了讨论。理论分析对相关的断裂等间距问题研究提供参考。

Study on spacing between fractures in a group

In order to forecast the space situation and the law of the fracture occurring,the complexity of the development of a quantitative theory of the phenomenon of uniform spacing fractures is determined by the need to simulate the behavior of a medium having the properties of elastic deformation in fracture.The paper studies uniform spacing fractures by theoretical method.At the same time,one dimension model is established.We describe the stress-field distribution and the conditions of strain-incompatibility of the spacing between fractures in a group by non-Euclidean mode and analyze the effect of non-euclideanness parameter on uniform spacing fractures.The theoretical analysis is valuable as a reference for the question of uniform spacing fractures.
