摘要: This study performed a three-dimensional (3-D) finite element numerical analysis on a retaining piles stabilized slope of Ali-Shan Wu-Wantzy landslides (or Ali-Shan landslides) at Chia-Yi County to inspect the slope stability and in-situ lateral earth pressure acting on the piles. In addition, two groups of model slope, namely, colluvium slope (homogeneous slope) and colluvium-bedrock slope (heterogeneous slope) were set up for a series of numerical experiments on the design parameters of retaining pile to investigate their influences on the slope stability and the mechanical behaviors of retaining piles. The analysis results indicate that the pile length turns to be influential to the factor safety if the retaining piles are installed at the central area of the homogeneous slope. In addition, the mobilization of maximum bending moment of retaining pile in steeper heterogeneous slope is greatly influenced by the penetration depth of pile into bedrock.
本研究對嘉義縣阿里山五彎仔地滑區之擋土排樁穩定邊坡,進行三維數值分析,以檢核邊坡之穩定性及現地擋土排樁承受之側向土壓力。此外,亦建立崩積層邊坡(均質邊坡)與崩積層-岩層(異質邊坡)兩組擋土排樁穩定模型邊坡,以探討擋土排樁各項設計參數,對邊坡穩定性及排樁力學行為之影響。分析結果顯示,若在均質邊坡之坡面中央區域打設排樁,則排樁打設長度,對邊坡安全係數有顯著影響。同時,在較陡之異質邊坡,排樁最大彎矩受排樁入岩深度比之影響甚鉅。
