在地质小构造研究中,对节理裂隙面的数据处理,包括地层复平后裂隙面变化产状计算、极密点的计算、各应力轴产状的计算、剪裂角计算等等的工作量都很大。因此,很有必要建立数学计算模式,使之能用电算或计算器来完成这一复杂的计算工作。这既可节省人力和时间,还可减少作图中的误差,确保工作质量。在《地质构造分析的赤平极射投影方法》一书中,虽已给出上述各项计算的数学模式,但对裂隙面产状随地层复平变化的计算方法却过于复杂费时费工。本文在此介绍一种简捷的计算方法以资完善。
In geologic small structure research, the data processing of joint fracture surface includes the calculation of fracture surface variation after occurrence of stratigraphy recovery, calculation of extremely dense points, calculation of each stress axis occurrence, calculation of shear angle, etc. It’s all great. Therefore, it is necessary to establish a mathematical calculation mode so that it can use computer or calculator to complete this complex calculation. This can save manpower and time, reduce errors in mapping, and ensure the quality of work. Although the mathematical models for the above calculations have been given in the book “Geological Structural Analysis of the Zeping Polar Projection Method”, the calculation method for fracture surface occurrence and stratigraphic recovery is too complex and time consuming. This article describes a simple calculation method to improve.
