Abstract

One of the most important problems in foundation engineering is determination of the ULTIMATE BEARING CAPACITY of underlying soil. Exact solution will be obtained based on limit state theorems when upper bound and lower bound solutions are the same. A correct stress field, which does not violate yield criteria, is required to find a lower bound solution. An acceptable failure mechanism is required to find an upper bound solution. Ordinary finite element programs can obtain stress distribution in soil mass but cannot obtain the related failure mechanisms. Different types of interface elements may be used for modeling relative displacements between two surfaces, but they need a prescribed location in the region of interest. This limitation enforces the use of a time consuming adaptive mesh algorithm for finding the failure mechanism. For accurate and efficient determination of ULTIMATE BEARING CAPACITY and the corresponding failure surface a new type of finite element has developed. Using this element, the failure surface is automatically simulated and utilized to accurately determine the ultimate bearing capacity.
