| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 88 === 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.
