摘要
梨山地滑區由數十個滑動土體所組成,而面積達230公頃,由於德基水庫及臺灣重要的東西連絡道路台八線及台七甲線均位於此地區,因而自民國七十九年發生滑動造成台七甲線中斷後,政府便持續進行各項整治工程,並設立由量測至傳輸均採自動化之監測系統,以監視地層滑動情形及瞭解整治工程成效,並作為未來地滑區管理基準值訂定之依據,這些監測系統運作已有相當時間,系統亦已達穩定成熟之狀態,本文介紹梨山地滑區之概況、監測系統設置原則及實際運作之方式,並舉例說明利用這些資料進行地滑整治成效評估、區域性之地滑管理值之訂定及地滑區管理之未來發展之方向。
英文摘要
The Lisan land slide area consists of many sliding blocks within an area of approximately 230 ha. Because of a reservoir and island crossing highways located in this area, the government initiated tremendous efforts on stabilizing the area since a slide occurred in April, 1990. An automatic system was set up for monitoring the ground movement and ground water table variation in order to evaluate the effect of engineering remedial works. The system has been working for some time under a stable condition. This paper describes the system, including its planning, operation, and utilization of the data obtained from this system.
