N2  - The portable in-situ testing equipment, such as piezoprobe and Dynamic Cone  Penetrometer, are simple and inexpensive tools which can be used to determine the  consolidation and strength characteristic of soils. These equipment were used in this  research at different test site in Thailand together with some conventional tools, including  piezocone and Standard Penetration Tests.  Fifteen (15) piezoprobe dissipation tests were performed in very soft clay layer  from 4 m to 9 m depth at Nong Ngu Hao Test Site. The horizontal coefficient of  consolidation was estimated by matching the measured and theoretical dissipation curves.  The estimated ch value from piezoprobe are about almost the same as results from  piezocone dissipation test at 5 m depth. At 8 m depth, the miniature piezoprobe gives  higher ch value than results from piezocone by about 2 times.  Nine (9) portable dynamic cone penetrometer tests were performed in sandy soil  at Test Site A and B in Rayong. The penetration resistance of dynamic cone ( DCP  Number) are correlated with standard penetration blow counts (SPT N value). The field  correlation agrees well with simplified theoretical solution for both 8 kg and 4kg sliding  hammer
