Geotechnical Design Parameters for a Metro Tunnel from Pressuremeter Tests

Sundaram, Ravi / Gupta, Sanjay / Gupta, Sorabh / Lal, Bhajan

Abstract Being an in situ test, the pressuremeter provides a reliable assessment of soil parameters, eliminating the influence of sample disturbance. The paper outlines the analysis of pressuremeter data to interpret parameters such as undrained shear strength, pre-consolidation pressure, over-consolidation ratio, and in situ horizontal stress. The test was used effectively in conjunction with borehole data to assess the geotechnical parameters for the design of a metro tunnel. Data from two locations along the metro tunnel alignment are presented here.
