水可以存在于地壳中很深的部位。由于水的可压缩性很小,再加上毛细作用,水就在含水孔隙中造成流体压力,从而改变了岩体中的应力状态。而岩石的形变性质和流体的形变性质有明显的差别,所以流体压力所造成的应力场的改变以及流动的地下水的动态性质所造成的流体压力的连续变化,都对地质体系的形变特点起着不可忽视的影响。从油、气、水及地热资源的开发,地震的成因及控制,用土壤及岩石来支撑工程建筑,地壳对电波及机械波的响应,热液矿床的形成等许多方面来说,了解流体渗透的地质体系的形变特点显然都是重要的。各行业中的科学家和工程师都力求对支配
Water can exist deep in the earth’s crust. Due to the small compressibility of water, coupled with capillary action, water causes fluid pressure in the water-containing pores, changing the stress state in the rock mass. The deformation properties of rocks are obviously different from those of fluids. Therefore, the change of stress field caused by fluid pressure and the continuous change of fluid pressure caused by the dynamic nature of flowing groundwater all play important roles in the deformation characteristics of geological system Can not be ignored effect. From the development of oil, gas, water and geothermal resources, the causes and control of earthquakes, the support of engineering buildings with soils and rocks, the response of crust to radio waves and mechanical waves, the formation of hydrothermal deposits, etc., The deformation characteristics of the geological system are obviously important. Scientists and engineers in all industries are striving to dominate
