Purpose of Loading Test

1. Verification against the design purposes

● Loading Test ▷Determine the load allowance

▷Pro-vide as basic materials for design

2. Check if it can support design load

● Loading Test ▷ Calculate the load allowance

▷ Review the stability

3. Establish construction management stand-

ards for piles

● Loading Test ▷ Pile movement analysis ▷Establish

construction management standards

Types of Loading Tests

1. Static Loading Test

● Compression loading test(Dead load-Kentledge,

Reaction pile, Earth anchor method)

● Lateral loading test (Dead load, Reaction pile method)

● Tensile loading test

2. Dynamic Loading Test

● End of i Initial driving(EOID) test

● Restrike test

3. Plate Loading(Bearing) Test

● Plate loading test (construction and roads)

● Large scale plate loading test

● Measure load and displacement

● Calculate the allowed bearing capacity of the pile

● Check the stability of the foundation


● Drivability Analysis by GRLWEAP

● Pile movement analysis(Stress, Bearing capacity and Integrity)

● Separate measurement of friction and end bearing capacity

3. Plate Loading(Bearing) Test

● Measure bearing capacity of foundation

● Calculate modulus deformation and reaction

coefficient of foundation

Results of Loading Test

Test-related Regulations(Code)

Fig8. Lateral Loading Test(Cast-in-place Pile)

■ Test using end bearing capacity of the pile

and mutual reaction force of circumference

friction by installing bi-directional jacks at the

end of cast-in-place piles

Principle of Bi-directional Load Test

Advantages and Disadvantages

1. Advantages

● Cost-efficient and safe when test load is big

● Can measure the friction and end bearing capacity at the same time

● Reduce work space and high efficiency

● Limited ton specific piles and low applicability

● Equilibrium between friction and end bearing capacity

and Jack can be wasted

2. Disadvantages

Test Result(Measurement Items)

● Measure load, upward, downward and pile top displacement

● Equivalent load-settlement curve drawing

● Calculate allowable bearing capacity and evaluate basic stability

■ To check the integrity of cast-in-place piles.

In other words, to check the internal defects

such as material separation, pores and section

change

Purpose ofIntegrity Test

● Need to make a test hole before construction

● Numbers and paths of test holes

Sonic Echo Method(PIT)

● No need of test holes(sonic echo method)

● Issue stress wave after attaching an accelerome-

ter on the top of the pile

● Measure the particle velocity of the top of the

pile against micro time

● Check impedance (EA/C) of the pile

● Related regulations(Code) ; ASTM D 5882

■ It is to identify the composition, thickness of

soil stratum and the engineering characteristics

of soil in order to provide basic materials for

design and construction including foundation

of structure, stability of slope, cutting method

and stability.

Purpose of SubsoilInvestigation

■ Material survey and site visit(Identify status

and Draw topographic map)

■ Preliminary Survey(Earth surface geology

survey, Satellite and Aerial pictures analysis)

■ Main Survey(Boring investigation, Field survey,

Exploration geophysics, Laboratory soil test

and Other special tests)

Classification of Subsoil Investigation

1. Boring Test(Size ; NX, BX)
