Question

Question 2 (25 %) A plate load test with plate dimensions of 20 cm x 20 cm, is performed at a construction site underlain by homogeneous medium dense sand with SPT blow counts of N60 20 blows/30 cm. The plate load test results are presented in the form of load vs. settlement plot given in Figure 2. By using the plate load test results, attempt to develop the load vs. settlement plot for a mat foundation with 20 m by 20 m dimensions. Please use the plot provided below to express your results Plate Load Test Results 240 200 160 z 120 80 40 10 20 30 40 50 Settlement (mm) Figure 2. Plate Load Test Results
