摘要
本文提出了三种估算RQD指标的方法:Farmer节理密度估算法;体积节理计数估算法;精测线估算法。实践证明,这三种方法简单、经济且具足够的精度。
Three methods for estimating rock quality designation(RQD) are presented in the paper, i, e., parmer, s method by estimating joint density,estimation method by volume-joint counting, and estimation method through precise measuring line,These methods have been proved through practice to be simple, economical and with sufficient precision.
