hi all,
i am beginner in down-hole seismic test, but now i involved in project part of down-hole/cross-hole seismic testing for shear wave velocity and compression wave velocity refer to ASTM D 7400-08. i need some reference recommended books related down-hole/cross-hole seismic testing, if...
hi all,
kindly need your advise about this,
i involved in superblock project (apartment and hotel 26 storey), soil profiles accross site describe as below (average soil boring consistent) :
0-1.5 m : clay (N-SPT 60 = 5)
1.5 - 40 m : sand (N-SPT > 60)
our geotechnical team have been choosing to...
hi all,
can anyone have experience regarding PIT interpretation as attached? is this data acquisition acceptable or not or its really defect at depth 4-5 m?
thanks,

hi all,
i have problem with CSL test on test-pile with instrumented pile. but CSL test in this test pile indicated that pile has defect from depth 0-7 m (debonding)at all pair tube, and for tube pair 1-2 and 2-3 at depth 8-13.6 m (with remark 70% velocity reduction).
can anyone give technical...
Dear All,
kindly need your help, Whether the PDA result as attached is correct? since the velocity graph above of force graph.

hi all,
as we know LEM (limit Equilibrium Method) as one of ways to define SF on Slope Stability Analysis (Bishop, Janbu, Fellenius, Spencer, Sarma), and currently we also know FEM (Finite Element Method to define SF on Slope Stability Analyis, as my limited of experience about both of this...
Hi All,
i am begineer in pile testing, i have some question about axial, lateral and uplift load test,
as i know, static load test often combination with instrumentation such strain gages, tell-tales extensometer, pile integrity thermal, and others. the purpose of instrumented test pile are to...
Hi all,
i have little experienced about estimate load transfer on bored pile using strain gages while performing axial compression static loading test (cyclic) in different level of pile, previously i just analyze using Hooke Law to calculation the load transfer. but recent i found Bengt...
All,
pls help,
1. what formula to calculation the best diesel hammer can i use for piling regarding weight of ram.
