摘要

This report discusses the correlation of Texas Cone Penetrometer (TCP) test values and shear strength of Texas soils. Data collected over the past decade by the Texas Department of Transportation (TxDOT) from several parts of Texas were used to verify the current correlation between TCP blow count and the undrained shear strengths of clays with higher (CH) and low liquid limits (CL), sandy clay (SC) and other soils. Over 4000 sets of data were used to verify the current TxDOT relationships for the entire state of Texas and three TxDOT districts from where most of the data were collected. Limited field studies were performed to verify the current TxDOT relationship with CH and CL soils. Based on the data available and statistical analyses, linear and nonlinear relationships between undrained shear strength of soil and TCP blow count have been developed. The statistical parameters including the probability distribution functions (PDF) for the undrained shear strength (Su) and TCP blow count (NTCP ) based on the type of soil were determined.
