中文摘要 | 本文主要的內容是探討底承於台北盆地礫石層之場鑄基樁應用不同承載力設計公 式時安全係數與破壞機率之對應關係,並藉此探討以可靠度為基礎之場鑄基樁承載力設計之 相關問題。分析結果顯示,台北盆地之場鑄基樁安全係數為3.0時,對應之破壞機率之範圍 約為4.5*10□到7.0*10□,這個結果與國外學者之分析結果相似。分析結果也顯示,安全 係數除了必須視可靠度要求而定外,也與設計公式之種類及試樁詮釋法等有很密切之關係, 不過土壤參數和試樁結果之統計資料都略嫌不足,必須有賴進一步的研究才能將分析結果應 用到實際之工程。 |
英文摘要 | Reliability method is adopted to obtain the safety factor and its corresponding probability of failure for different axial capacity design formulas of cast-in-place piles. The piles studied herein are those embedded in the gravel stratum under the Taipei basin. In addition, the applicability of the reliability approach and relevant issues are examined. analytical results show that failure probability corresponding to a safety factor of 3.0 is about 4.5*10□ to 7.0*10 □ for cast-in-place piles installed in the Taipei basin. Appropriate safety factor should be decided accounting for the reliability requirement, pile design formula used, and the method adopted for the interpretation of pile test results. Further study is needed before the results can be used in actual design due to limited statistical data of gravely soil and field pile test. |
