NEW METHOD FOR ESTIMATING TRACE LENGTH OF DISCONTINUITIES AND ITS ENGINEERING APPLICATION
一种估计结构面迹长的新方法及其工程应用

According to geometrical relationship between discontinuities and measuring window and referring to H-H method for trace length estimation,a new expression is proposed to express probability relationship between trace length of discontinuity and its orientation. Base on Laslett method for trace length estimation, generalized the H-H method for trace length estimation is put forwad,which overcomes some disadvantages of H-H method and extends its area of applications. Using this method,an application example of rock engineering is analyzed.
