摘要：
The cone pressuremeter is a new site investigation device which incorporates a pressuremeter behind a standard cone penetrometer tip. This Paper seeks to develop an understanding of the new device, and to establish a procedure to allow the test to be used to determine the engineering properties of cohesionless soils. A series of calibration chamber tests is described, in which three cone pressuremeter prototypes of different cross-sectional areas were used. A programme of calibration designed to examine the influence of relative density, stress level and stress ratio on the values of limit pressure obtained from the cone pressuremeter test and the cone resistance values obtained from the cone test is presented. A procedure for deducing the in situ horizontal stress, density and friction angle is described, and is used to back-analyse the test data.
