Static Pile Load Tests

The fundamental requirements on pile load tests are set out in the EC 7-1 Handbook (44), DIN EN 1536, DIN EN 12699 and DIN EN 14199. This chapter comprises a compilation of recommendations for executing static pile load tests. In the chapter, concerning the directions of forces, differentiation is made between: along the pile axis (axial), and lateral to the pile axis. Static lateral load tests are normally carried out to determine the lateral resistance and deformations in the serviceability limit state. In long, slender piles the failure state cannot normally be achieved under loads lateral to the pile axis; this is only possible in short, rigid piles. Micropile load testing is dealt with separately, even when only static axial loads are involved. The chapter lists the principles that are to be followed for installing test piles, for conducting static axial load tests on micropiles.
