ON MECHANICS OF HEAVILY RElNFORCED GRANULAR MATS

抄録

Based on an experimental observation by Haung and Tatsuoka (1988) a mathematical technique first proposed by the Author, Poorooshasb (1982), is employed in the development of an analytical procedure to achieve the solution to a certain class of problems associated with the performance of heavily reinforced mats supported by weak subgrades. The class of problems that can be handled by the present analysis include ; (i) mats supporting point loads, uniformly or symmetrically distribute loads, (ii) mats bridging over voids appearing in the subgrade after construction and (iii) mats placed over nonuniform forms of ground subsidence. The analysis presented is essentially an engineer's approach and compares, in simplicity, to a similar approach used in the analysis and design of shallow beams.
