臺灣地貌多變且山坡地佔比較高，隨著公共工程需求增加，不可避免需在陡峭邊坡上進行建設。然而，傳統大規模開挖工法對環境造成嚴重衝擊。本研究旨在探討一種兼顧施工安全、效率與環境永續的基礎工法，即竹削工法搭配井式基礎在陡峭邊坡工程中的應用成效。為此，本研究選定「機場捷運A7站區區外道路新闢工程」與「台7線32K+500災害復建工程」兩個代表性案例，從環保減碳性、生態保育性、監測成果安全性及經濟性等四大面向進行全面評估。 本研究結果顯示，竹削及井基工法相較於傳統工法具有顯著優勢：在環境方面，本工法能大幅縮小開挖規模（案例一減少約 62%，案例二減少約 76%），能最大限度維持邊坡原始輪廓，且完工後植被覆蓋率可迅速回復至施工前90%以上，展現強大的環境復育力與節能減碳效益。在監測安全方面，傾度管監測系統證實邊坡變形穩定，證明其在高陡坡上具有可靠性。在經濟效益方面，竹削及井基工法相較傳統工法可節省約28%-30%的工程費用，具備高度的成本效益與推廣潛力。為提升未來工程實務，建議未來相關標案應採統包模式以降低設計與地質現況之落差，並將施工便道與構台空間納入前期規劃，以預控空間衝突與安全風險。同時，應將廠商技術實績列入評選標準，並編製標準化施工指引。最後，應結合低碳材料規定與BIM數位移交機制，以落實公共工程之永續維管。;Taiwan′s diverse topography and high proportion of mountainous terrain necessitate public infrastructure development on steep slopes. However， traditional large-scale excavation methods often impose severe environmental impacts. This research aims to investigate the efficacy of an integrated approach—combining the Bamboo-cut shaped Excavation with Well Foundation—to achieve a balance between construction safety， operational efficiency， and environmental sustainability in steep slope engineering. To this end， two representative cases， the "Airport MRT Linkou A7 Station Peripheral Road Construction" and the "Tai 7 Highway 32K+500 Disaster Recovery Project，" were selected for a comprehensive evaluation across four dimensions: carbon reduction， ecological conservation， structural safety monitoring， and economic viability. The results indicate that the Bamboo-cut shaped Excavation and Well Foundation methods offer significant advantages over traditional techniques. Regarding environmental impact， this approach substantially reduces the excavation scale (by approximately 62% in Case I and 76% in Case II)， effectively preserving the original slope profile and enabling vegetation coverage to recover to over 90% post-construction， demonstrating superior ecological resilience and carbon reduction benefits. Safety monitoring via inclinometer systems confirmed the stability of slope deformation， verifying the structural reliability of these methods on steep gradients. Economically， the proposed approach achieved cost savings of 28% to 30% compared to conventional methods， highlighting its high cost-effectiveness and potential for broader application. To optimize future engineering practices， this study suggests adopting Design-Build (DB) procurement to bridge the gap between geological surveys and site conditions. Furthermore， construction access roads and platform layouts should be integrated into the preliminary design phase to preemptively manage spatial conflicts and safety risks. Finally， contractor technical expertise should be incorporated into the evaluation criteria， alongside the establishment of standardized construction guidelines， low-carbon material mandates， and BIM-based digital handovers to ensure the sustainable maintenance of public infrastructure.
