PROBLEM TO BE SOLVED: To predict the corrosion quantity of a cast iron pipe, and to rank the pipe relative to the deterioration degree, over the whole of buried piping.;SOLUTION: The area under which the cast iron pipe is laid is partitioned into a plurality of blocks. The corrosion depth of the cast iron pipe laid under each block is expressed by the equation; y=kTa (y:the corrosion depth, T:an embedding period; k:a constant based on an embedding geology, a:a constant). The value of k in each block is determined by investigation on the corrosion degree of the pipe body at each embedding spot and the geology of each embedding ground. The deterioration degree of the pipe in each block is evaluated by the determined value k.;COPYRIGHT: (C)2004,JPO&NCIPI
