Abstract

It is useful to select an appropriate mathematical model to predict landslide. Through observation and analysis of real-time measured time series, a reasonable mathematic model is chosen to do prediction of landslide. Two theoretical models, such as polynomial function and growth model, are suggested for the description and analysis of measured defermation from an active landslides. These models are applied herein to describe the main characteristics of defermation process for two types of landslide, namely polynomial and growth models. The TRS (tensiof rotation and settlement) sensors are applied to adopt two models, and the data analysis of two field (Neurpjae and Buksil) resulted in good coincidence between measured data and models.

사면 붕괴를 예측하기 위해서 적당한 수학적 모델을 선택하는 것은 매우 유용하다. 시간열로 실시간 계측된 자료를 통하여 합리적인 사면붕괴 예측용 수학모델을 선정할수 있다. 3차 방정식을 이용한2가지 형태의 이론적 모델이 이 연구에서 사용되었다(Polynomial 및 Growth형). 사면의 변위각 및 침하를 계측할 수 있는 계측기가 느릅재 및 북실 현장에 적용되어 모델의 적용가능성을 점검하였다. 그 결과 계측 자료와 두 가지 수학모델과 아주 높은 일치성을 보였다.
