| 摘要： | Engineering soil properties, including undrained shear strength, overconsolidation ratio (OCR), coefficient of earth pressure at rest, Young's modulus, and cyclic degradation factors, obtained by various in situ and laboratory testing methods are presented for two Texas Gulf Coast sites. Soil deposition was deltaic, and preconsolidation occurred as a result of desiccation, producing local variability, as well as variability from site to site. The most comprehensively studied property, OCR, is in the range of 3 to 7 at Site A below a depth of 3 m, in which the soils to a depth of 8 m were formed in a pro-delta environment. Site B, at which the soils to a depth of about 11 m were formed in a backswamp environment several km from Site A, indicated that OCR values are two to three times as high. Properties at Site A are probably appropriate for conservative geotechnical design at most sites in the geographical area. |
