本研究團隊過去已成功將三維解耦分析方法應用於開挖引致之不同基礎形式及鄰房位置之鄰房損害分析並進行探討，但對於開挖角隅處之斜置鄰房其結構損害與角變量反應，仍需進一步研究與討論。因此本研究最主要建立開挖角隅處斜置鄰房之解耦分析，並根據分析結果，探討開挖沉陷對於斜置鄰房結構損害之影響。接著，除了斜置鄰房外，也將獨立基腳鄰房結構物置於開挖區中心及開挖角隅區之間三種位置，以探討不同鄰房位置之角變量行為並找出關係式之適用範圍。最後，改變斜置鄰房設計地震力以及利用結構物側推分析，探討地震帶與非地震帶之鄰房對於開挖引致之結構損害，以及對鄰房服務狀態之影響。
斜置鄰房之研究結果顯示，其結構彎矩變化及塑性鉸發生位置，與受到開挖兩側沉陷槽之影響相關，也導致開挖之地表沉陷型式與過去不相同，呈一波浪狀。不同鄰房位置之角變量行為之研究結果顯示，開挖區中心至開挖角隅區之鄰房皆可適用楊家睿(2021)建立由自由場角變量推估基礎角變量之線性關係式。斜置鄰房則因角變量比值與距離之關係，與過去研究不同，因此本研究建立一個新的斜置鄰房推估基礎角變量之關係式。最後，改變斜置鄰房之設計地震力以及結構物側推分析之研究結果顯示，位於高度地震帶之鄰房，因梁柱設計之鋼筋量較多，使結構物之韌性提高，受開挖引致之結構損害較小，對鄰房服務狀態影響也較小。

The Three-Dimensional Decouple Analysis Method（DAM）has been successfully applied to study the excavation-induced adjacent building damage behavior for different types of foundation and adjacent building locations in past few years by previous researchers of our research team. However, the angular distortion behavior and building damage of obliquely placed adjacent building at excavation corner still need further research and discussion. The main purpose of this study is to establish the decoupling analysis of the obliquely placed adjacent building at excavation corner. According to the results of the DAM, explore the influence of excavation-induced settlement on the structural damage of the obliquely placed adjacent building at excavation corner. In addition, the spread footing adjacent building was also placed in three locations between the center of the excavation area and the excavation corner area, in order to explore the angular distortion behavior of different adjacent building locations and determine the applicable range of the relationship. Finally, by changing the design seismic force of the obliquely placed adjacent building and using the pushover analysis of the structure, the impact of the excavation-induced structural damage and the service status of the adjacent building in the seismic zone and the non-seismic zone were studied.
The result of the obliquely placed adjacent building showed that the structural bending moment and the plastic hinge were influenced by the settlement troughs formed on both sides of the excavation, which also lead to a different pattern of settlement during excavation than in the past, showing a wave shape. Than, the result of the different locations of adjacent building showed that the relationship established by Yang (2021) can be applied to the adjacent building between the center of the excavation area and the excavation corner area. The relationship between the angle distortion ratio and the distance of the obliquely placed adjacent building was different from previous studies. Therefore, this study establishes a new relationship of the obliquely placed adjacent building. Finally, the result of the obliquely placed adjacent building in the seismic zone and the non-seismic zone showed that for the adjacent building in the high seismic zone, the toughness of the structure is improved, the excavation-induced adjacent building damage and the impact of the service status are small.
