應用地電阻影像剖面法於滑動邊坡之研究

Studies of sliding slopes using Resistivity Imaging Profiling method

指導教授 : 楊潔豪

摘要


台灣以人口密度高及地形陡峻著。地質環境脆弱多變,百分之七十以上為山區地形,在特殊的地理、地質與人文條件,坡地災害防治研究是一必須面對的課題。其中崩積層厚度、地下水位面、地質構造等特性為崩塌地研究時所必須事前獲得的重要資訊。 本研究係利用地電阻影像剖面法(Resistivity Image Profiling; RIP),選定「義興」、「隆華」、「草嶺」、「松茂」、「佳陽」與「萬大」等六處崩塌地進行滑動邊坡之研究,並配合研究區域中的露頭電阻及鑽探資料進行比對,描繪出測區地層之電性剖面,與探討其地質型態、地層組成、組態及含水層與水中所含物質對電之高敏感特性與電阻率之相對關係。 在不同地質型態研究區域所佈設之十七條地電阻影像剖面探測成果,均能確實描繪出研究區域之崩積層厚度、地層層位關係與界面、地下水位深度、裂隙延伸方向與潛在滑動面等,並歸納出「隆華」、「松茂」與「萬大」屬於弧型界面之滑動型態,「義興」、「草嶺」、「佳陽」屬於沿坡面方向之地表滑動,且在「隆華」與「佳陽」兩處,探測出具有高角度岩層界面之異常變化電阻,可提供測區基本地質資訊,有助於後續坡地防災研究。

並列摘要


Taiwan is known for its dense population and steep topography. The geologic environment is frangible and variable. Seventy percent of the land is covered by Mountains. Due to theses special geography, geology and humane conditions, researching a method to decrease the disaster caused by sliding slopes has become an important area of interest. Therefore, the information related to a potential sliding slope site such as the thickness of colluvium, the groundwater level, the geologic setting, etc. must be known beforehand. This research used the resistivity image profiling (RIP) method to study six potential sliding slope sites namely Yi-Sing, Long-Hua, Cao-Ling, Song-Mao, Jia-Yang and Wan-Da respectively. The outcrop resistivities and the lithologic logs at each site were used to aid the RIP sounding data interpretation. The geologic setting and aquifer condition can be compared to the sounding results. Seventeen RIP profiles were obtained from these six sites with different geologic characteristics. Each profile does reflect the thickness of colluvium, the boundaries of layers, the depth of groundwater level and the extension direction of slip plane. An arc type slip was shown at the sites of Long-Hua, Song-Mao and Wan-Da. A plane slip can be recognized at the Jia-Yang, Yi-Sing and Cao-Ling sites. In addition, the resistivity sections shown in Long-Hua and Jia-Yang also indicated a high angle contact plane between layers. Our results do provide basic information of these sliding slope sites and can benefit the prevention of landslide disaster.
