  2. Wave equation analysis - Wikipedia

    en.wikipedia.org/wiki/Wave_equation_analysis

    The model mathematically represents the pile driving hammer and all its accessories (ram, cap, and cap block), as well as the pile, as a series of lumped masses and springs in a one-dimensional analysis. The soil response for each pile segment is modeled as viscoelastic-plastic. The method was first developed in the 1950s by E.A. Smith of the ...

  3. Continuous flight augering - Wikipedia

    en.wikipedia.org/wiki/Continuous_flight_augering

    This creates a continuous pile without ever leaving an open hole. Continuous flight augering can be used to construct a secant piled wall which can be used as a retaining wall or as shoring during excavation .

  4. Dynamic load testing - Wikipedia

    en.wikipedia.org/wiki/Dynamic_load_testing

    Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber ...

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  6. Piling - Wikipedia

    en.wikipedia.org/wiki/Piling

    A deep foundation installation for a bridge in Napa, California, United States. Pile driving operations in the Port of Tampa, Florida. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.

  7. Keras - Wikipedia

    en.wikipedia.org/wiki/Keras

    Keras is an open-source library that provides a Python interface for artificial neural networks. Keras was first independent software, then integrated into the TensorFlow library, and later supporting more. "Keras 3 is a full rewrite of Keras [and can be used] as a low-level cross-framework language to develop custom components such as layers ...

  8. Screw piles - Wikipedia

    en.wikipedia.org/wiki/Screw_piles

    Modern screw pile design is based on standard structural and geotechnical principles. Screw pile designers typically use their own design software which has been developed through field testing of differing compression pile and tension anchor configurations in various soil profiles. Corrosion is addressed based on extended field trials ...

  9. Pile driver - Wikipedia

    en.wikipedia.org/wiki/Pile_driver

    Tracked vehicle configured as a dedicated pile driver. A pile driver is a heavy-duty tool used to drive piles into soil to build piers, bridges, cofferdams, and other "pole" supported structures, and patterns of pilings as part of permanent deep foundations for buildings or other structures. Pilings may be made of wood, solid steel, or tubular ...
