Soil classification using the cone penetration test
Several charts exist for evaluating soil type from electric cone penetration test (CPT) data. A new system is proposed based on normalized CPT data. The new charts are based on extensive dataExpand

Evaluating cyclic liquefaction potential using the cone penetration test
Soil liquefaction is a major concern for structures constructed with or on sandy soils. This paper describes the phenomena of soil liquefaction, reviews suitable definitions, and provides an updateExpand

Interpretation of cone penetration tests — a unified approach
The electric cone penetration test (CPT) has been in use for over 40 years and is growing in popularity in North America. This paper provides some recent updates on the interpretation of some keyExpand

Estimating liquefaction-induced ground settlements from CPT for level ground
An integrated approach to estimate liquefaction-induced ground settlements using CPT data for sites with level ground is presented. The approach combines an existing CPT-based method to estimateExpand

Soil behaviour type from the CPT: an update
An initial application of CPT results is to evaluate soil type and soil stratigraphy. One of the more common CPT-based methods to estimate soil type is the chart suggested by Robertson et al (1986)Expand

Seismic cone penetration test for evaluating liquefaction potential under cyclic loading
Impressive progress has been made in the last 25 years in recognizing liquefaction hazards, understanding liquefaction phenomena, and analyzing and evaluating the potential for liquefaction at aExpand

An approach to evaluation of field CPTU dissipation data in overconsolidated fine-grained soils
Dissipation of excess pore pressures during piezocone testing in firm to stiff overconsolidated fine-grained soils provides data curves that cannot be interpreted using published theoreticalExpand

Estimating the undrained strength of sand: a theoretical framework
A framework for estimating the ultimate undrained steady state shear strength of sand (Su) from in situ tests, which combines the theory of critical state soil mechanics with shear wave velocityExpand

Estimating coefficient of consolidation from piezocone tests
Data have been reviewed from sites in Europe and North and South America as well as published data from South Africa. The review has concentrated on dissipation data from piezocone tests (CPTU) toExpand
