      Aug 15, 2015· Note: As the modulus (E) values given above have been obtained by experiments on low strains, calculation of settlement made with these values may yield high value. Hence the following factors of safety are recommended to be adopted for settlement analysis. A high factor of safety of 2 to 3 is given for high E values corresponding 10 to 80 mm penetration and a factor of safety of only 1.2 to 2 ...
