    Abstract: 山崩事件易受天氣條件(如:豪雨、颱風)觸發,若能在地滑敏感區進行監測,比較降雨前後敏感區的構造改變,便能對山坡地的整治與災害預防提供有益的資訊。
    ;Because Electrical Resistivity Tomography(ERT) is fast, cheap and accuracy is used to resource exploration and engineering survey, especially disaster prevention. Electrical resistivity survey was carried out continuously for three months to monitor a hazardous hillslope at Jieshou Junior High School in Taoyuan.
    The monitor site is located at hillslope between the school building and playground. The length of survey line is 67.5 m. The electrode array is alternate array, which is different from traditional array like Wenner array or Dipole-Dipole array. The instrument will measure automatically every day. The study analyzed the data from 2014 June 5 to 2014 September 29. Except ERT profiles of different dates, also calculates the rate of change of resistivity between base model and monitor data, to observe the weak change. Then refer the data from Central Weather Bureau, to discuss the relation between the observed values, rainfall and air temperature. We can observe after heavy rainfall, observed value would decrease, but no obvious change as air temperature change. Through the comparison of inverted sections and rate of change of different time, and comparison of inverted section of real data and synthetic model, we can know the route of infiltration at horizontal coordinate 35 to 45 meters.
