| 英文摘要 | It is widely accepted that residual soils (RSs) form very differently from sedimentary soils. While there have been extensive advances regarding sedimentary soil, little is known about the strain stiffness decay in RS. This study considers granite residual soil (GRS) from Taishan in China, where stiffness behaviors are established using in situ and laboratory investigations. Variability in the soil stiffness is due to its current state, including the depth, test method, and strain. This is established via systematic resonant-column and in situ tests. In situ tests include the seismic dilatometer Marchetti test (SDMT) and the self-boring pressuremeter test (SBPT). The degree of weathering of the test soil varies significantly along the depth direction, and the top layer of the soil has a hardening shell due to severe weathering. The laboratory G-gamma decay curves of GRS were determined from the resonant column. A comparison of the shear modulus (from SBPT) obtained by different analysis methods gives the shear modulus from nonlinear analyses. An approach is proposed to properly describe the trends in typical in situ G-gamma decay curves based on data from the tests. The G-gamma curve obtained from the resonant-column test of GRS was compared with the in situ curves. The shear modulus G, as obtained from laboratory tests, is smaller than the curves of the in situ tests, which reflects the processes of sampling, transportation, and preparation of soil specimens. |
