摘要(中) 製備基礎承載試驗所需之層狀試體。藉由改變岩體不同地層狀況及層厚
比(H/B) 來探討淺長條基礎之極限承載力及其破壞模態。並透過數值分
析模擬與試驗對照以了解淺長條基礎在不同地層狀況下之承載行為。
經由研究結果顯示，由Hill (1950)、Chen (1975) 及Chen & Drucker
(1969)等學者理論預測之岩石承載力，預測值與試驗值皆有所偏差。Bell
(1915)、Sower (1979)、Wyllie (1992) 等學者之承載理論之預測值較接近
本文試驗值。層狀地層之承載理論中，砂岩在頁岩之上承載力預測方面
以Meyerhof & Hanna (1980) 承載理論最為準確，頁岩在砂岩之上承載力
之預測則以Myslivec & Kysela (1978) 經驗式較接近試驗值。最後本文以
加權平均之概念提出層狀地層承載力模式，經由求出上下岩層承載力、m、
Zmax等四個參數，本模式能預測層狀岩盤的承載力。摘要(英) In this thesis, foundation tests carried out through reduced scale models,
the layered samples used of bearing capacity tests are prepared in methods and
techniques used by predecessors. This thesis investigates the bearing capacity
of shallow strip footing and failure models of layered stratum by changing
different geological condition. It could be comprehended that the behaviors of
shallow strip footing overlying stratum in different geological conditions
through numerical analysis and model tests.
According to the results of the sandstone and shale bearing capacity tests,
it could be observed that test results were different from the result of methods
proposed by Hill (1950), Chen (1975) and Chen & Drucker (1969), and results
of theoretical methods proposed by Bell (1915), Sower (1979), Wyllie (1992)
were closed to test results. The limit equilibrium method of Meyerhof & Hanna
(1980) had more accurate prediction of the result of sandstone overlying shale.
As to geological condition of shale overlaying sandstone, the empirical method
proposed by Myslivec & Kysela (1978) was more accurate at capacity forecast.
In this paper, an alternative method was proposed and verified the validity by
former solutions.關鍵字(中) ★ 承載
