工程岩体不连续面几何参数的估计

ESTIMATION OF GEOMETRIC PARAMETERS FOR KEY-DISCONTINUITIES WITHIN ENGINEERING ROCK MASSES

岩体中的不连续面对工程性质有很大的影响。特别是那些产状不利并且贯通整个工程范围的不连续面对工程性质有决定性的影响。本文提出基本节理面参数和工程节理面参数的概念,并把工程节理而分为关键节理面和非关键节理面讨论。由基本节理面的几何参数可以估计任何工程范围内工程节理面的几何参数,如间距、迹长和出现概率。一般的情况下基本节理面和工程节理面的几何参数是不同的。

Discontinuities in rock masses have a major effects on engineering properties,in particular,like such discontinuities that are unfavorable in orientation and are contin- uous within overall engineering rock masses.The conception on the parameters of ba- sic joints and engineering joints is proposed in this paper.In adddition,the engineer- ing joints were divided into key-joints and non-key-joints for discussing further.The spacing,length and appearing probability within any range of engineering rock mass ca...
