OPTIMIZATION ARRANGEMENT OF MEASURING-LINE IN BACK ANALSIS OF UNDERGROUND-STRUCTURE LOADS
地下结构荷载反算中的测线网优化布置

The back analysis of measured displacements is very available to determine the underground-structure loads. The scheme of independent measuning-line network is put forward for the back analysis. The criterion to optimize independent measuning-line network is presented.The theoretic basis is found to arrange correctly measuring-line in back analysis of underground-structure loads. The idea of the optimization arrangement of measuring-line can be applied to another back analysis of measured displacements.
