👉A pile foundation may consist of a group of piles, joined by pile cap at the top and typically spaced at 2 to 4 timers the pile diameter.

There are two modes of failure for pile group, namely individual pile failure and block failure.

During design, the distribution of axial load among the piles is assumed uniform.

However, center piles are expected to carry greater loads than perimeter piles in sand.

The reverse is true for pile group in clay.

Block failure on the other hand, is more likely to occur in fine-grained soil rather than coarse-grained soil.

It may be induced when the pile spacing is less than 2 to 3 times the pile diameter.

👉Leveling Method, commonly used in civil engineering and surveying.

🚧​Mastering Slope Calculation

💫​The image demonstrates the relationship between vertical height difference (\Delta H) and horizontal distance (L) to determine the percentage of a slope.

​Key Components Explained:
​Elevation A: The starting ground point (32.000 m).
​Backsight (BS): The rod reading at the known point (2.105 m).

​Instrument Height (I.H.): Calculated as {Elevation A} + {Backsight} = 34.105{ m}.

​Foresight (FS): The rod reading at the new point (0.607 m).

​Elevation B: Calculated as {I.H.} - {Foresight} = 33.498 { m}.

​Height Difference (Delta H): The rise between points A and B (1.498 m).

​The Formula:
​To find the slope (S), we use the ratio of the height difference over the horizontal distance, multiplied by 100:

With a distance of 98.90 m and a height change of 1.498 m, the resulting slope is 1.514%.
