Problems solved by technology
Because the roughness coefficient of the rock mass structural surface has the characteristics of size effect, that is, with the increase of the scale of the rock mass structural surface, the roughness coefficient value of the rock mass structural surface decreases, and the probability of the complete exposure of the rock mass structural surface in the field is less than 5%. The rock mass structural surface roughness coefficient JRC obtained by this technique n The value varies with the exposed area of the rock mass structural surface, which has uncertainty, and is not applicable to the rock mass structural surface roughness coefficient JRC with size effect n determination

A method for determining roughness coefficient of rock mass structure surface includes sampling multiple measurement sections with length of 10 cm for each, plotting profilogram for said sections and measuring out fluctuation range Ryo of profilogram, applying formula of JRCo = 49.2114e 29/450arctan (4Ryo/5) to calculate roughness coefficient JRCo value for each said section, obtaining expected value E(GRCo) by utilizing JRCo, using mode of JECn = E (JRCo)(Ln/Lo) ¿C D to convert out roughness coefficient JRCn value of rock mass structure surface.
Description
(1) Technical field The invention relates to a method for determining the roughness coefficient of a rock mass structural surface, which is suitable for determining the roughness coefficient JRC of a rock mass structural surface on the surface of a partially exposed rock mass structural surface n value occasions. (2) Background technology Before the present invention was made, the method for determining the roughness coefficient of the rock mass structural surface in the prior art was to replace the roughness coefficient JRC of the rock mass structural surface with the roughness coefficient value obtained by measuring the range of the exposed rock mass structural surface n value. Because the roughness coefficient of the rock mass discontinuity surface has the characteristics of size effect, that is, with the increase of the scale of the rock mass discontinuity surface, the roughness coefficient value of the rock mass discontinuity surface decreases, and the probability of t...
