I have seen engineers using 1% of pile diamater as an estimate for setllement pile when the maximum load (or capacity) is reached. Where did this come from? Any references?
Where uplift controls the design of building or bridge foundation, you may consider micro piles to resist both compression and tension loads. In granular till-like soils, it is not uncommon to achieve a shaft friction of 10 to 12 kips per lineal foot (or higher) of pile for an 8-inch diameter...
Renovations of a c. 1926 Fire Station are planned. The building has a basement and is supported on timber piles with concrete pile caps. Groundwater is near the top of pile caps. The planned renovation will increase loads on the existing piles. Any non-destructive testing that can be used to...
Hi dpa,
Rokery is very common in the Pacific NW, Seismic zone 3. It is normally used to retain a cut, not fill. Wall height of up to 12 feet or so is not uncommon. If rockery is used to retain fill, the state of practice is my area is to limit the wall hright to no more than about 4 to 5...
novs,
Just a few comments for your considerations:
1. Since the utility in question will be in new, it may be quite tolerant to vibration. A moitoring program to document the before, during, and after construction conditions should be helpful.
2. The highest level of vibration in sheetpile...
Wick drain is a good idea if the construction schedule allows the new fill to sit for a while while the underlying soils consolidate. What about something like gepiers? Depending on your height, the geopiers may not need to extend to the base of soft soils (you need to do a stability anaysis to...
