摘要：

Structural　topology　optimization　belongs　to　0-1　programming　problem　essentially.　The　structural　topology　optimization　model,　which　is　established　by　ICM　(Independent　Continuous　Mapping)　method,　is　extremely　nonlinear.　In　this　paper,　according　to　the　high　order　contraction　method,　the　object　functions　and　the　constraint　functions　of　the　structural　topology　optimization　model　are　expanded　in　logarithm?　space;　consequently,　it　gets　a　more　precise　approximate　description　than　the　model　expanded　by　Tyler　expansion,　and　makes　the　procedure　of　model　optimization　get　a　more　precise　solution.　And　according　to　the　ICM　method　and　the　method　raised　in　this　paper,　the　topology　optimization　problem　of　continuum　structures　is　solved.
