What are the types of pile foundation?

There are three types of pile foundations according to their construction methods which are driven piles, cast-in-situ piles, and driven and cast-in-situ piles.

What is the purpose of pile foundation?

The primary function of a pile foundation is (a) to transmit the load of a structure through a material or stratum of poor bearing capacity to one of adequate bearing ca- pacity; (b) in some instances, to improve the load-bearing capacity of the soil; and (c) to resist lateral loads and to function as a fender to …

How many types of pile tests are there?

These include three distinct methods: Nuclear radiation, or gamma-gamma method. Short wave (ultrasonic) acoustic method. Long wave (sonic) acoustic method.

What is PDA test pile?

The Pile Driving Analyzer® (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day.

What is test pile and working pile?

4.22. I) Test Pile Any pile to which a test loading is, or is to be, applied. J) Ultimate Bearing Capacity The load at which the resistance of the soil becomes fully mobilised. K) Working Load The load which the pile is designed to carry. L) Working Pile One of the piles forming the foundation of a structure.

What is a weap analysis?

Wave equation analysis is a numerical method of analysis for the behavior of driven foundation piles. It predicts the pile capacity versus blow count relationship (bearing graph) and pile driving stress. The method was first developed in the 1950s by E.A. Smith of the Raymond Pile Driving Company.

What are the types of pile test?

There are essentially two main types of pile load tests: the preliminary pile test and the working pile test. A preliminary pile test is typically carried out before the piling works commence while the working pile test is carried out during piling or when substantial piling works are completed.

What is a PDA pile test?

High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day. PDA tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer.

What are pilings for foundations?

A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.

What are types of piles?

Depending upon their function, the different types of piles are, Bearing piles. Friction piles. Sheet piles. Anchor piles. Batter piles. Fender piles. Compaction piles.

What is the difference between pile and pier foundation?

The difference betwcen pile foundaiion and pier foundation lies in the method of construction. Though pile foundations transfer the load through friction and/or bearing, pier foundations transfer the load only through bearing. Generally, pier foundation is shallower in depth than the pile foundation.

What are the types of pile?

The most common types of deep foundations are pile, piers and caissons. A pile is a slender structural member made of steel, concrete or wood. A pile is either driven into the soil or formed in-situ by excavating a hole and feeling it with concrete.
