摘要
以野外实测地质剖面在DGSInfo系统剖面库中的岩层真厚度计算结果出现负值及0值进行探讨,并与以列昂托夫斯基公式为厚度计算公式的结果进行对比分析,且对DGSInfo系统剖面库及列昂托夫斯基公式中岩层倾向与坡向的关系进行探讨,在此基础上,确认岩层厚度计算中负厚度识别及负号的应用,并厘定较为合理的岩层厚度计算公式和在计算岩层总厚度时较为科学的负值处理方法,进而对出现负厚度及0值厚度的原因进行分析,且对岩层负厚度所代表的地质意义作了较为详细地解释。
According to the comparison of analysis about the negative thickness and the zero value of the calculation of the true thickness of strata appearing at the Digital Section System and the result calculating from Leon tibor scitovsky formula in a geological section,and the knowledge of mankind all clearly indicate the importance and difficulty in recognition and using of the negative sign about the calculation of the true thickness of strata. The paper detailedly analyses the value of ＂sign＂ from the Digital Section System and the Leon tibor scitovsky formula,in which ＂1＂ stands for the tendency of rock stratum is contrary to the slope,and ＂-1＂ stands for the tendency of rock stratum is same to the slope.Based on the above analyses,the paper formulates the reasonable calculation formulas and the scientific handling methods in negative thickness,analyses the geological meaning of the negative thickness.
