Thank you for your posts, and validating my suspicion of the osmosis theory.
The soil is dense glacial till and the performance tests all passed. Also, no problems during materials testing of the shotcrete facing.
The areas with moisture on the facing appear random and localized, more like...
I am involved in a project where a permanent soil nail wall was recently constructed, wall height ranges up to 20 feet, the permanent facing is trowled shotcrete. The retained soils are c-f Sand, some to trace gravel, some to trace silt, cobbles and boulders are numerous. Groundwater is within...
Thanks dgillette, I did not consider previous methods which were likely used to develop a correlation between N and SWV.
I feel that hammer corrections are warranted. However, I suspect that the committee responsible for developing this standard must have considered this issue. Unfortunately...
I have never been clear on whether N-values should be corrected for hammer type, rod length, etc. when determining the seismic site class. So, we recently purchased a copy of ASCE 7-10 hoping it would shed some light. As I read ASCE 7-10, it clearly states that uncorrected N-values should be...
