From for 5cm.
(4) single-spot testing: retest 10 times when single-spot testing, 10 test values reject 2 maximum values and 2 minimums
It is worth, then test value of the average value of remaining 6 test values as single-point.It is successively individually surveyed according to the single-spot testing method
Point test, determines 16, survey area single-spot testing value.
(5) it individually surveys area's test value: from 16 single-spot testing values in the survey area, rejecting 3 maximum values and 3 minimums
It is worth, then test value of the average value of remaining 10 single-spot testing values as the survey area.
(6) it individually surveys area's Surrounding Rock Strength: area's test value N will be surveyed and substitute into formula:, the survey area can be obtained
Surrounding Rock Strength value R.
(7) step (2) ~ (5) are repeated, records and calculates and determines that other survey area's test value.
(8) step (6) are repeated and calculate determining other surveys area's Surrounding Rock Strength value R,
(9) Surrounding Rock Strength: four different area's Surrounding Rock Strength value R that survey are averaged, four area Ge Ce Surrounding Rock Strength of gained is flat
Mean value is as the tunnel section Surrounding Rock Strength value.
The technology of the present invention effect:
Using Surrounding Rock Strength test method of the present invention, Surrounding Rock Strength in front of tunnel can be carried out in the construction of tunneling boring hard rock mole
Quickly test, without carrying out core boring sampling, the testing time is short, and information feedback in time, facilitates development machine operator according to country rock
The variation of intensity carries out the setting and adjustment of boring parameter, and tool wear is facilitated to predict, and then obtains good tunneling construction effect
Fruit.The Surrounding Rock Strength method for rapidly testing can be grasped quickly and easily suitable for the construction of hard rock tunnel full face tunnel boring machine
Surrounding Rock Strength in front of tunnel, provides beneficial reference for the efficient rapid construction of tunneling boring hard rock mole, has important guidance
Meaning is worthy of promotion and application.
