本文根据反射波理论时距曲线方程又推导出一种直接计算反射层位产状的公式,它更具有灵活性(锤击点可不位于排列中点)。同时介绍了利用这些计算式的 PC—1500计算机程序以及算例。
In this paper, we derive a formula to directly calculate the position of reflection layer according to the time-distance curve equation of reflection wave theory. It is more flexible (the hammer point can not be located at the midpoint of arrangement). At the same time, the PC-1500 computer program and the example which use these formulas are introduced.
