摘要

由於都市發展及人口壓力，坡地利用不斷提升；但於利用之際，常遇滑崩現象，使坡地易呈不穩定型態，於是治理與防治技術因之而起；然而以往採用之法，大都費時、費力，無經濟實用價值，導致推廣不易，不能達到全面防治之目的。故本研究旨在尋求簡易實用之有效坡地穩定處理法，以便全面推廣，初步研究結論如下：(一)壓實處理對抑制坡地滑崩可立刻發生作用，在淺層小規模滑崩救急處理上尚有推廣應用價值。(二)石灰處理在短期內無法發揮其控制坡地滑崩的功效，長期功效則有待進一步探討。(三)坡地滑崩如不予適當處理，則有加強擴大之趨勢，惡性循環勢所難免。有效治理法之探討必須諸位專家學者共同努力以赴。

Owing to the development of urban communities and the pressure of increasing population, the use of slopeland already became one important way to solve ＂the problem of the need of land. While using slopeland, people noticed the phenomenon of landslip, and offered various methods, technics to manage and to prevent landslip. But those methods which we practiced take a lot of time and money, and, above all, they can not completely attained the end of full prevention of landslip. So it is no practically economic value to use the methods which had been offered past to prevent landslip. The subject of this study is to search out several simple treatments which can prevent landslip effectively. The results of the initial research are as follows: (1) It is effectual by using the compaction treatment of drop hammer to restrain the landslip of slopeland, Especially in the rapid control of small superficial landslip, using the compaction treatment of drop hammer always can get a good result unexpectedly. (2) The-quicklime treatment can not completely control the landslip of slopeland in short time. It is necessary to improve the technics of the quicklime treatment. (3) If we can not handle the landslip of slopeland properly, then the landslip will be increasing continuously.
