How about the final work status? How about the load distribution curve along the pile ? Xx'>5d>

The skin friction occurs due to relative displacement between soil and pile. As you said, the upper part of pile work first. The skin friction at this point may also be negative skin friction when the clay has big settlement. That is the neutral plane coming from. nZ bg

When the external load is quite small, it will be carried by the upper part. Do not forget, when you design the pile, it is the ultimate value or design value(considering safety of factor) Ec\x;li! *

The load test is used to make sure the design. b]JN23IS2

I have some load test data and strain gage in the pile (constructed in clay,about 25m) to monitor the load distribution in the pile. jSG
