【Abstract】 There are two problems in elastic multilayered pavement with the transfer matrix calculation. One is the problem of inverse of matrix, the other is how to set height of half space part. Through research the paper provides a simple method to simplify the inverse process. And a method is gained in this paper so that the final answer has nothing to do with the height of half space part. The corresponding formulas are listed. The calculation results are in good agreement with the correct answer.更多还原
