Abstract: A lateral stress sensing cone penetrometer (LSSCP) was designed and fabricated. Based on the results of calibration chamber tests in sand, relationships between measured lateral stress, in-situ lateral stress, and relative density were developed. Field tests at an artificial sand island demonstrated the feasibility of obtaining reasonable values using the instrument.
