plane of weakness การใช้

• Transform faults also act as the plane of weakness allowing for the splitting in rift zones.
• This creates a horizontal plane of weakness called a " cold joint " between the two batches.
• Others have compound structure, in which large units are composed of smaller units separated by persistent planes of weakness.
• Because foliation planes are planes of weakness, these dipping towards a free surface, failure is likely to occur along these planes.
• Rapid shearing can then occur along these planes of weakness, giving rise to an earthquake in a mechanism similar to a shallow-focus earthquake.
• They tend to be larger than shallow landslides and form along a plane of weakness such as a scarps at the top and steep areas at the toe.
• The meristem itself is the least calcified portion; sometimes there is no mineralization at all, which makes it a plane of weakness where breaking often occurs.
• There are often oblique pre-existing faults, planes of weaknesses or striations to the fault slip, which do not belong to the conjugate fault sets.
• Additional benches on the margin of Whitman Bench are due to deep-seated slumping of large blocks, which also creates planes of weakness for future slippage and channels for water infiltration.
• Rock slides are the most dangerous form of mass-wasting due to the fact that they incorporate a sudden, incredibly fast-paced release of bedrock along a uniform plane of weakness.
• A small dyke of porphyritic microgranite which has " a dog's-leg shape " in plan was intruded into these rocks during the Devonian Period; this formed a plane of weakness which controlled the position of the fault.
• A second theory supposes that desert pavements form from the shrink / swell properties of the clay underneath the pavement; when precipitation is absorbed by clay it causes it to expand, and when it dries it cracks along planes of weakness.
• Soft ground drilling can be undertaken using a rotary auger or wash boring techniques, while rock drilling often use methods such as NMLC which allow for recovery of a core of material which can be examined to determine the strength, degree of weathering, understanding of any how intact the rock is ( RQD ) and identify any discontinuities or other planes of weakness.
