  2. Deep foundation - Wikipedia

    en.wikipedia.org/wiki/Deep_foundation

    Both the diameter of the pile and the depth of the pile are highly specific to the ground conditions, loading conditions, and nature of the project. Pile depths may vary substantially across a project if the bearing layer is not level. Drilled piles can be tested using a variety of methods to verify the pile integrity during installation.

  3. Pile integrity test - Wikipedia

    en.wikipedia.org/wiki/Pile_integrity_test

    Pile integrity testing using low-strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations. The test measures: pile length, or depth to anomalies; pile head stiffness; pile shaft mobility, which is dependent on pile section and concrete properties

  4. Franki piling system - Wikipedia

    en.wikipedia.org/wiki/Franki_Piling_System

    Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base. [4]

  5. Bearing capacity - Wikipedia

    en.wikipedia.org/wiki/Bearing_capacity

    Meyerhof (1951, 1963) proposed a bearing-capacity equation similar to that of Terzaghi's but included a shape factor s-q with the depth term Nq. He also included depth factors and inclination factors. [Note: Meyerhof re-evaluated N_q based on a different assumption from Terzaghi and found N_q = ( 1 + sin phi) exp (pi tan phi ) / (1 - sin phi).

  7. Depth in a well - Wikipedia

    en.wikipedia.org/wiki/Depth_in_a_well

    The depth reference point is the kelly bushing in the United States and a few other nations, but is the drill floor in most places. Differential (or relative) depths or thicknesses should generally be specified with at least two components: a unit and a path, plus any eventual specifiers to remove any possible ambiguity.

  8. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    During uniform flow, the flow depth is known as normal depth (yn). This depth is analogous to the terminal velocity of an object in free fall, where gravity and frictional forces are in balance (Moglen, 2013). [3] Typically, this depth is calculated using the Manning formula. Gradually varied flow occurs when the change in flow depth per change ...

  9. Foundation (engineering) - Wikipedia

    en.wikipedia.org/wiki/Foundation_(engineering)

    Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
