The constructing tableland railways including Qing-zang railway and other planned railways are all facing the threat of debris flow calamity. It is necessary and of practical importance to study the early warning technology for this calamity. The type of debris flow and its distribution on Qing-zang plateau are analyzed. With the fuzzy neural network method the early warning model for judging the occurrence possibility of debris flow is established. According to the result of early warning, the safeguard operation for safe running under the threat is divided into three stages, i.e. forecast, early warning and alarm; and safeguard measures for safe running are formulated for different stages.
