    When to conduct pile load test

    Hi, After pile driven into soil, when is the appropriate time to conduct the pile load test (maintained load test & pda test) 1. Is the resting period for skin friction and end bearing pile is different? I read that some suggesting straight away, some said 3 days, 2 weeks and even 1 month. 2...

    Can i use undrained value for slope stability?(application of UU test)

    Hi, Can i use the cu value (phi=0) obtained from the UU test for slope stability analysis instead of using c' value from CIU test? If no, why it is not possible to use the undrained strength for slope stability calculation. I have road embankment failure/road foundation failure and only UU...

    Skin Friction Pile shall be terminated in which layer?

    Hi,[shadeshappy] if someone could help me to understand this problem better. 1. For example if i have 8m stiff clay with underlying 10m loose sand.(only example) The pile will be mainly on skin friction. So let say i want to terminate the pile 9m b.e.g.l (including 8m into stiff clay and 1m...

    Pile set and Pile load test - Friction pile vs End Bearing pile

    Hi, Can someone brief me the criteria of pile set and pile load test for friction pile and end bearing.Please correct me if im wrong as well. Friction pile - no set taken during driving, wait for at least 2 weeks for dissipation of negative pore water pressure n mobilisation of the friction...
