Whether lateral load test can be allowed prior to vertical load test
Whether lateral load test can be allowed prior to vertical load test
(OP)
Load test (vertical & lateral) is to be carried out on same pile. Contractor wants to do the lateral load test first and then after a month will carry out vertical load test on the same pile.
Please suggest me whether this will provide a correct picture on vertical compression capacity since due to lateral load test around 4-5D of the surrounding soil will be disturbed and side friction may not generate.
How much time it will take for soil (clayey silt) to come back to its original position and regain its strength (thixotropic action).
Or do we suggest to perform the vertical load test first and then go for lateral load test.

Actually, whether any references are there where this time requirement of regaining soil strength is established? Probably, for overconsolidated soil, the gap between pile and soil continues to persist if lateral load test done first and thus shaft friction will not be generated for that part when vertical load test will be performed.Is it true?

When you run a lateral load test, you run the risk of separating a significant portion of the pier/pile from the adjacent soils. Loss of contact means loss of axial capacity. That's why you need to run the axial test first.
