Rock Mechanics - Conjugate Fractures - P37
Просмотров 7192 года назад
Problem 37. The figure below shows a block of fine-grained limestone that was experimentally shortened by about 1% at room temperature. Four sets of fractures developed. Fractures of sets ‘‘a’’ and ‘‘b’’ are conjugate shear surfaces (the angular relationship between which can be measured directly on the diagram). Fractures of set ‘‘c’’ are extension fractures that formed during loading. Fractur...

Assume that σ1 is horizontal, and that the confining pressure is equal the lithostatic load. a) What is the maximum possible magnitude of σ1 that these rocks can support at 1500 m depth? Show your calculat...

Problem 40. Attached map showing the Johnson Valley Fault in southern California. This is a right-lateral strike-slip fault that lies a short distance to the north of the San Andreas Fault zone. On June 28, 1992, one of the largest earthquakes in recent decades occurred on the Johnson Valley Fault, a magnitude 7.5 event named the ‘‘Landers earthquake’’. This large earthquake presumably released...

    i dont understand how the angle of the axial plane between a 55° and a 48° dipping limb can be greater than both of them? shouldn't the axial plane be tilted with (55+48)/2 ?

    An open pit rock slope at your mine is intersected by two fault planes and a set of major joints. The dips, dip directions and friction angles of the faults and joint planes are given in the table below: Plane Dip Dip direction Friction angle Fault 1 60° 114° 23° Fault 2 80° 250° 20° Joint set 1 40° 120° 25° The dip and dip direction of the slope are 40° and 164° respectively. Use the stereonet provided to determine whether there is potential instability in the slope. Then using the wedge stability charts provided, determine the factor of safety of the slope. Comment on the confidence you have in the factor of safety determined considering the advantages and disadvantages of the methodology used.

    • @mortazapirouz7482
      @mortazapirouz7482 Год назад

      You can obtain the dip direction of the fault plane. You should read the strike and dip of the fault plane on the stereonet. Read it in the Right Hand Rule convention, and then add 90 to the strike azimuth, and that will be the dip direction.
