摘要

地滑地之研究分爲室內試驗及野外試驗兩部份。室內部份對兩地區之地滑地粘土之理化性質加以分析與探討。野外部份在屏遮那地區鑿集水井和截水溝以處理地下水與地表水，並實施植生工程以穩定崩坍地之邊坡。在中興嶺地滑地區除實行地表與地下之排水處理及擋土牆與攔砂埧之處理外，同時在滑動區內埋設應變計，伸縮計，間隙水壓計，水位計與雨量計等儀器以觀測各種抑止工程施工後之移動量和降雨量與地下水位之關係，以探討其施工效果。

This paper summarized the field and the labolatory experimental results for preventing the landslide in Chung Hsing-Ling and Pin-Zau-Nair. According to the results of investigation, We made the drainage treatments in surface and underground in both area. The surface ditch has operated to draw run-off out of the landslide region. The collecting wells have digged in order to drain out the groundwater which exists in the sliding layer. Besides, in order to research the operational effect of restrain engineerings, such as sabo dam and retaining walls, We installed the instruments of expansion gauge, water gauge and underground strain gauge in Chung Hsing Ling landslide to observe the displacement of the ground, and the relationship between rainfall and ground water level before and after the restrain engineerings.
