bridge abutment settlement
bridge abutment settlement
(OP)
Dear all
Im looking at a bridge which has suffered from settlement since construciton 20 years ago. It is beleived the abutments were built on mass concrete fondations on Weald Clay, and this clay wasnt allowed to presoncolidate fully due to time constraints.
How do it test the clay beneath the abutment foundations? I was planning on comapring that with another neary by borheoles result to see how much the it could theoritically consoliate and how much much consoldaition has taken place already (beneath the abutmenet) and how much more can be expected.
Please advise.
Thank you

Some testing ideas:
CPT's, particularly with dissipation testing can be quite useful.
Cored boreholes with slug testing
Cored boreholes with frequent push tube samples to run 1-D consolidation tests on.
That being said, you really need advice from a senior / principal geotechnical engineer at your firm for a job like this.
