Astm D 1143 07.pdf: A standard for testing deep foundations under static axial compressive load

Astm D 1143 07.pdf is a document that contains the standard test methods for deep foundations under static axial compressive load. It was issued by ASTM International, an organization that develops and publishes voluntary consensus standards for various materials, products, systems, and services. Astm D 1143 07.pdf was first approved in 1950 and has been revised several times since then. The latest edition was published in April 2007.

Astm D 1143 07.pdf provides minimum requirements for testing deep foundations under static axial compressive load. It applies to all types of deep foundations that function in a manner similar to driven piles or cast-in-place piles, regardless of their method of installation. It also covers testing single piles or pile groups. The test results may not represent the long-term performance of a deep foundation, but they can provide useful information for assessing its capacity, load response, deflection, side shear resistance, end bearing, and creep settlement.

What are deep foundations and how are they tested

Deep foundations are structural elements that transfer loads from a structure to a deeper layer of soil or rock that has sufficient bearing capacity and stiffness. Deep foundations are used when the shallow soil layers are weak, compressible, or unstable, or when the structure requires a large load-carrying capacity or resistance to lateral forces.

Some examples of deep foundations are piles, drilled shafts, caissons, micropiles, helical piles, and piers. Depending on their shape, size, material, installation method, and loading condition, deep foundations can be classified into different types.

Types of deep foundations and their applications

TypeDescriptionApplication

PilesCylindrical or tapered elements that are driven or jacked into the groundUsed for supporting bridges, buildings, offshore structures, retaining walls, etc.

Drilled shaftsCylindrical elements that are constructed by drilling a hole in the ground and filling it with concreteUsed for supporting bridges, buildings, towers, dams, etc.

CaissonsLarge-diameter drilled shafts that are constructed under water or in wet soil conditionsUsed for supporting bridges, piers, docks, offshore structures, etc.

MicropilesSmall-diameter drilled shafts that are reinforced with steel bars or pipesUsed for strengthening existing foundations, stabilizing slopes, supporting retaining walls, etc.

Helical pilesPiles that have one or more helical plates attached to their shaftsUsed for supporting lightweight structures, solar panels, signs, etc.

PiersVertical columns that are constructed by excavating a shaft in the ground and filling it with concrete or masonryUsed for supporting bridges, buildings, monuments, etc.

Test methods and procedures for deep foundations

To test the performance of deep foundations under static axial compressive load, Astm D 1143 07.pdf allows the following test procedures:

Procedure A: Quick Test - A simple test that loads the foundation relatively quickly as load is increased.

Procedure B: Maintained Test - A test that loads the foundation in larger increments and for longer intervals.

Procedure C: Loading in Excess of Maintained Test - A test that loads the foundation beyond the maximum load reached in Procedure B.

Procedure D: Constant Time Interval Test - A test that loads the foundation at constant time intervals regardless of load increments.

Procedure E: Constant Rate of Penetration Test - A test that loads the foundation at a constant rate of penetration regardless of load increments.

Procedure F: Constant Movement Increment Test - A test that loads the foundation at constant movement increments regardless of load increments.

Procedure G: Cyclic Loading Test - A test that loads the foundation cyclically with varying load levels and durations.

Benefits and limitations of Astm D 1143 07.pdf

Astm D 1143 07.pdf has several benefits and limitations as a standard for testing deep foundations under static axial compressive load. Some of them are:

Astm D 1143 07.pdf provides minimum requirements and procedures for testing deep foundations under static axial compressive load. It does not specify design criteria or interpretation methods for the test results. The engineer in charge of the foundation design should approve any deviations or additions to the requirements of Astm D 1143 07.pdf.

Astm D 1143 07.pdf applies to all types of deep foundations that function in a manner similar to driven piles or cast-in-place piles. However, it does not cover other types of deep foundations such as grouted anchors, soil nails, or ground improvement techniques.

Astm D 1143 07.pdf allows different test procedures that may produce different load-displacement curves. The engineer should select the most appropriate test procedure based on the objectives, scope, and budget of the test program. The engineer should also consider the effects of factors such as soil conditions, loading rate, creep, and consolidation on the test results.

Astm D 1143 07.pdf provides useful information for assessing the capacity, load response, deflection, side shear resistance, end bearing, and creep settlement of deep foundations under static axial compressive load. However, it does not provide information on other aspects such as lateral resistance, torsional resistance, dynamic response, or long-term performance of deep foundations.
