According to the statistic data on hazards occurred in Xinjiang line of New Eurasian Continental Bridge in recent 40 years, the number of dameged sectors in Xinjiang line is analyzed and forecasted by using fuzzy-Markovian chain forecasting method and principle.

Combining the engineering characteristic and the theory of Markov chain, this paper inferred the forecast model of fuzzy Markov chain, which had the fuzzy division of conditions and characteristics of no following effects in the main.

By establishing the prediction model for deterioration of reinforced concrete bridge based on the fuzzy Markov Chain,this paper expatiates the classification of deterioration grades of bridge structure and determination methods for fuzzy deterioration states.

Application of weighted Markov chain to prediction of precipitation;

The weighted Markov chain model of Jinan annual rainfall

And the dryness and wetness status is forecasted by applying weighted Markov chain.

Then based on the verification of the Markov chain characteristics of precipitation,the weighted Markov chain used for predicting the state of precipitation in Beijiang River Basin has been .
