The embankments are classified into three different classes depending on the quality of the available data.  A new term called 'critical depth' is defined, and it is shown that  the circle with the minimum factor of safety lies between 0 & 2.5 m below the position of the minimum strength in a subsoil which exhibits a classical strength profile with a crust of high strength at the ground surface. A design factor of safety of 1.2 for Bangkok embankments is proposed.  Two sets of design curves are developed, one for embankments on Bangkok soil  and the other for embankments in other regions. The new design curves give better solutions for soils with low PI values, a range in which the Bjerrum curve failed. An alternative method of design of embankments by using the bearing capacity factor, Ne, is also proposed. 0aShear strength of soils 0aEmbankments1 aBrand, E.W., eChairperson1 aBalasubramaniam, A.S., eExamination Committee1 aHolmberg, Soren, eExamination Committee2 aGovernment of the Netherlands, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno. 1009  3Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B23122
