Modeling a pile group with an "I" shape (group of piles at the top and bottom of the "I", tied together). I'm looking for some insight as to if the results I'm seeing "make sense." This particular scenario has 1000k compression on the top of the "I" and 1000k tension on the bottom of the "I". As...
Reaching out to see if anyone has a good reference or training module for performing site specific seismic studies for Site Class F evaluation. Thanks!
Hello. I have a question regarding settlement calculations for a small bridge abutment. 20’ span with 6’ of soil above the footing bearing elevation at the toe and 16’ at the heel. Would you consider the 6’ to be Df or 16’? Certainly the 6’ would be conservative, but that Df results in...
A general question on engineer’s responsibility. For a project where a geotechnical engineer performs borings and then those borings are provided to another entity (water tank designer-builder), who is then the geotechnical engineer of record? If the tank designer designs the foundations and are...
I'm looking at a project that requires excavation to about 25 feet depth over an area of about 20,000 sf, with bedrock at higher than the target depth (let's say rock at 20 feet on average). Groundwater is at about 5 feet. For this scenario, I'm anticipating temporary SOE would be installed to...
I've been asked (as the geotechnical engineer) to consider the use of shallow rock anchors for resisting uplift of a buried structure resulting from buoyancy of the structure (structure below groundwater level). I would typically design the rock anchors according to FHWA prestressed rock anchor...
Hello All - I'm looking to see if anyone here has a secant pile wall specification I can use as a basis for preparing a project-specific specification. Any help would be greatly appreciated. Thank you.
