二尖山地區地滑地之邊坡，經鑽探、試驗、現場觀測及數據分析結果，顯示地滑之最大因素除地質狀況不良外，降雨量之多寡乃其最大原因，據實驗結果顯示，飽和時之抗剪強度僅為自然含水量時抗剪強度之一半左右，並由邊坡穩定分析及埋設應變計地滑儀觀測研判滑動面之位置，獲得一致之互證。

The results from the boring, test, field investigation and data analysis on the land sliding In Er-jen Mountain show that the land sliding was caused by the bad geologic condition and the excessive amount of rainfall, which is the most important reason. According to the test, the shear strength of the saturated soli is only about one half of .the natural situation, To further prove this, we also use the slope stability analysis and the pipe strain gage to locate the land sliding surface. It is evidenced that the two methods lead to the same answer.
