FIELD TESTING AND NUMERICAL MODELLING OF BATTERED MINIPILE SYSTEMS

 

PROJECT AIM

Understanding the behaviour of group minipiles in cohesive soil as well as correlating driving data with its ultimate bearing capacity

 

METHODOLOGY

    DYNAMIC CONE PENETROMETER TEST

 

OBJECTIVES

Test Procedures

Compression test of footings as per ASTM DI 1 43, for both General and H6 footings

Tension test of footings as per ASTM 3689 for both General and H6 footings

  • Test
    CALIBRATED LOAD CELL
  • Test
    MULTIPLE FOOTINGS TESTED
  • Test
    TENSION TEST
  • Test
    COMPRESSION TEST
  • Test
    ENGINEERED FRAME

 

RESULTS

Analysis of failure loads and analytical method to predict future capacities based on geotechnical parameters

  • Result
    LOAD-DISPLACEMENT CURVES
  • Result
    ESTIMATION OF FAILURE LOADS

 

CONCLUSIONS

Battered minipile groups do not show full mobilisation of friction during tension loading

The efficiency of battered minipile groups is larger than the efficiency of vertical minipile groups in compression.
