本文主要目的在於探討面版勁度對於土釘擋土牆行為之影響，試驗所採用之模型砂箱尺寸為1.8 m*0.82 m*1.5 m，主要模擬基礎開挖之情況。在牆高1 m的模型砂箱以水平27.5 cm及垂直20 cm之間距埋設長度0.7 m的土釘，總共埋設三行土釘，每行安置五根。所採用之牆面版厚度分別為1.5 mm、2 mm及3 mm，而土釘之傾角分別為0度、15度及30度。經由開挖期間與開挖完成後，再以牆面水平位移量、土釘軸力、土釘彎矩及牆後土壤頂部沈陷量的量測結果進行分析。 The purpose of this research is to research the board stiffness on the behavior of soil nailing wall during excavation procedure. The experiment is to simulate excavation of 1.0 m high in sandbox of 1 .8 m*0.82 m*1.5 m. The length of nails is 0.7 m and buried with horizontal space of 27.5 cm and vertical space of 20 cm. There are three rows of nails. Every row has five nails. Using three kinds of boards with thickness of 1.5 mm, 2 mm and 3 mm, and three kind of nail obliquity of 0.degree., 15.degree. and 30.degree. to anlayze.
