（株洲工學(xué)院土木系 412008）[提要] 多支撐擋土結(jié)構(gòu)考慮開挖過程的計算方法，目前比較實用的主要有“m”法和“c”法兩種。對這兩種方法進行對比分析，進一步對擋土結(jié)構(gòu)一土一支撐的共同作用機理進行研究；并對土壓力取值，支撐預(yù)壓力的影響及土彈簧模型的選擇進行探討。
[關(guān)鍵詞] 多支撐 擋土結(jié)構(gòu) 開挖過程 “m”法“c”法The fairly practical calculation method that excavating course is considered in retaining structure of multistorey bracing, at present are "m" method and "c" method. On comparative analysis to this two kinds of methods, the retaining structure-soil-bracing jointly action on mechanism is studied; and the value of soil pressure, the influence of brace pressure and the selection of soil spring model are inquired into.
Keywords: multistorey bracing; retaining structure; staged excavation; "c"method; "m"method
