Step 1005-7, parameter obtains the parameter of Rock Mass Integrality according to areaK 2 ,K 2 =(S o - S p )/S o ；
Step 1005-8 obtains the parameter of Rock Mass IntegralityK, K=(K 1 + K 2 )/2；
Step 1005-9, according to parameterKNumerical value Rock Mass Integrality is defined.
7. engineering rock mass rock integrity according to claim 6 and relaxation zone test method, it is characterised in that: described
Step 1005-9 in, Rock Mass Integrality defines criterion are as follows:
WhenKWhen > 0.75, the integrality of current closed section is defined as rockmass；
As 0.55 <KWhen < 0.75, the integrality of current closed section is defined as more complete rock mass；
As 0.35 <KWhen < 0.55, the integrality of current closed section is defined as compared with fragmented rock body；
As 0.15 <KWhen < 0.35, the integrality of current closed section is defined as fragmented rock body；
WhenKWhen < 0.15, the integrality of current closed section is defined as rock mass smashed to pieces.
8. engineering rock mass rock integrity according to claim 1 and relaxation zone test method, it is characterised in that: the brill
The diameter in hole (11) is greater than 42mm, and the hole depth of drilling (11) is greater than 2m.
