How to determine whether the fill soil has consolidated
Thread Content
The project is located on the beach in Huangdao District, Qingdao. According to the geological survey report, the surface layer consists of undisturbed fill soil with a thickness of 2–5 meters, and it took approximately 2–5 years for this soil to be deposited there. I would like to know how to determine whether this surface layer of undisturbed fill soil is consolidated soil. The “Geotechnical Test Results Table” in the geological survey report provides the consolidation coefficients for soil samples taken at various depths; I’m not sure how to interpret these coefficients The consolidation coefficient is around 4.5x10-3 cm2/s~~
Original poster, you can carry out the calculations in accordance with the Code for Design of Building Foundations!
Recently filled soil with a age of 2 to 5 years can only be used as a bearing stratum for small and unimportant buildings; otherwise, the geological report would not refer to it as filled soil, but rather as clay. It is recommended to use pile foundations.
It is recommended that the original poster consult Section 6.5 \"Fill\" in the \"Code for Geotechnical Investigation\" (GB50021—2001). Geological exploration reports are prepared in accordance with these standards; as designers, it is important to pay attention to the geotechnical evaluation of the fill material to determine whether it can be used as a natural foundation.
