TESTE DEIN WISSEN
how to measure primary stress of a tunnel?
Lösung anzeigen
TESTE DEIN WISSEN
Stress measurements in tunnels are usually made in boreholes drilled beyond 'two tunnel diameters'.
Lösung ausblenden
TESTE DEIN WISSEN
why radial stress and shear stress at wall is 0?
Lösung anzeigen
TESTE DEIN WISSEN
The radial and shear stress are zero because the tunnel is filled with air which applies no shear or radial loading to the surface (except for atmospheric pressure).

TESTE DEIN WISSEN
how to increase the shear strength?
Lösung anzeigen
TESTE DEIN WISSEN
Considerable increases in shear strength accompany shearing with restricted dilatancy explain why limiting dilation on discontinuities by rock bolting can stabilize excavations in discontinuous rock.

TESTE DEIN WISSEN
Borehole breakout: difference in fracture mechanism, for limestone? for granite?
Lösung anzeigen
TESTE DEIN WISSEN
the limestone fails through the development of a shear fracture, whereas the granite fails through the development of tensile splitting.

TESTE DEIN WISSEN
Stress Relief Methods: what is the difference between overcoring and borehole-slotting?
Lösung anzeigen
TESTE DEIN WISSEN
In overcoring, the strains are measured that occur when the stresses acting on a volume of rock are relieved completely in all directions. In the borehole-slotting method, stress within the rock is only partly relaxedby the cut/bore.

TESTE DEIN WISSEN
what kinds of HPP do you know?

TESTE DEIN WISSEN
conventional; pumped-storage; run-of-river tide

TESTE DEIN WISSEN
how to measure P+S stress of a tunnel?
Lösung anzeigen
TESTE DEIN WISSEN
the 'Flat jack' method perform measurements at the tunnel wall and thus measure the primary+secondarystresses. PS, these methods are rarely used today for primary stress measurement.
Lösung ausblenden
TESTE DEIN WISSEN
which stress does Flat-Jack Method measures?
Lösung anzeigen
TESTE DEIN WISSEN
the sum of the primary and secondary stresses.

TESTE DEIN WISSEN
what is the 'discontinuity' of rock?
Lösung anzeigen
TESTE DEIN WISSEN
The word ‘discontinuity’ denotes any separation in the rock continuum having effectively zero tensile strength and is used without any generic connotation (e.g. joints and faults are types of discontinuities formed in different ways).
Lösung ausblenden
TESTE DEIN WISSEN
what is discontinuity spacing?
Lösung anzeigen
TESTE DEIN WISSEN
Spacingis the distance between adjacent discontinuity intersections with the measuring scanline
