摘要：

An　numerical　study　has　been　conducted　for　the　phase-changed　Stefan　problem　in　the　freezing　process　of　shaft　support　in　earth　with　liquid　nitrogen　or　liquid　carbon　dioxide　vaporizing　means.　The　method　of　equivalent　specific　heat　was　adopted　during　the　discretization　of　the　non-linear　equation　of　conduction.　With　the　developed　code　the　performances　of　single　cooling　tube　and　multiple　cooling　tubes　have　been　investigated.　In　addition,　an　optimized　result　to　the　arranging　pattern　of　the　cooling　tubes　for　an　actual　project　is　presented.
