Embodiment Construction

[0013] Figure 1 is the surface contour curve (length 400cm) of No. 1 structural surface of the Anji Limestone Fault, with point A at the left end as the reference point, point B at the middle point as the reference point, and point C at the right end as the reference point, and the selected lengths are 10cm, 20cm, and 30cm respectively , 40cm, 50cm,..., 360cm, 370cm, 380cm, 390cm, 400cm contour curves, respectively measured JRC 10 、JRC 20 、JRC 30 、JRC 40 、JRC 50 ,...,JRC 360 、JRC 370 、JRC 380 、JRC 390 、JRC 400 , see Table 1. It can be seen from Table 1 that the measurement with the left end point A as the reference point and the right end point C as the reference point is a valid measurement, and the measurement with the midpoint B as the reference point is an invalid measurement. The JRC measured from the contour curves whose lengths are 10cm, 20cm, 30cm, 40cm, 50cm,..., 360cm, 370cm, 380cm, 390cm, and 400cm with the left end A as the reference point and the right en...

Abstract

A method for measuring outline curve roughness coefficient of large dimension structure surface can realize effective measurement on outline curve roughness coefficient with different sampling length by confirming measurement reference point of outline curve roughness coefficient on large dimension structure surface.

Description

(1) Technical field [0001] The invention relates to a method for measuring the roughness coefficient of a large-scale structural surface contour curve, which is suitable for determining the measurement reference point when measuring the roughness coefficient on the surface contour curve of a large-scale structural surface, and performing effective measurement to study the roughness coefficient of a large-scale structural surface In the case of size effects. (2) Background technology [0002] Before the present invention is made, there is no method for measuring the roughness coefficient of the contour curve of the large-scale structural surface. Due to the non-uniformity of the roughness coefficient of the structural surface, statistical measurement must be carried out to obtain the roughness coefficient value of the large-scale structural surface. When measuring the roughness coefficient of structural surfaces with different sampling lengths starting from a certain measure...
