本研究根據 Terzaghi、Bjerrum 和 Eide 及基礎構造設計規範隆起檢核公式之分析結果,加以比較以探討其異同。根據研究 Terzaghi 方法當不考慮開挖面上破壞土體之側邊剪應力及基礎構造設計規範改以開挖面為圓心取破壞圓弧和 Bjerrum 和 Eide 的方法有類似的分析結果和意義。隆起分析時建議採基礎構造設計規範以開挖面為圓心的方法,安全係數取 1.2。;In this study ; the results obtained by Terzaghi's method ; Bjerrum and Eide's method ; and the Design Specification for Foundation are used to compare differences. Based on the research results from the Terzaghi's method where shear stresses are neglected on the side of failure soil body ; the Design Specification for Foundation where moment is taken at excavation bottom ; and the method by Bjerrum and Eide ; it is clear that all methods provide nearly the same analytical results and significance. Based on this study ; it is recommended that the Design Specification for Foundation where moment is taken at excavation bottom ; which suggests that basal heave be checked for deep excavation ; and a safety factor of 1.2 should be adopted. ; 計畫編號:NSC90-2211-E146-004;研究期間:9008~9107;研究經費:269 千元
