title: 遽變式山崩調查與動態模擬之研究 abstract: 摘要： This paper presents results of a case study on the Hsiaolin catastrophic landslide, including its kinematic process and the geometry of deposition. Based on geomorphologic analysis, the landslide initiated in thick, multi-aged colluvium soils at the headwaters of a small stream upslope of Hsiolin village. A three dimensional discrete element program, PFC3D was used to model interaction between the landslide and the Hsiaolin village. The landslide converted from debris and rock slide to debris avalanche during the kinematic process. The predicted velocity of initial motion was about 5 ~ 10 m/sec from source area. Then the predicted velocity was higher than 30 m/sec on steep terrain, a velocity which permitted the debris to cross Qishanxi stream and destroyed downstream village. 出版者：台灣: 中國土木水利工程學會出版日期： 2012-09 出處：中國土木水利工程學刊, 2012-09, Vol.24 (3), p.231-243 資源來源： Chinese Electronic Periodical Services (CEPS) 識別號： ISSN: 1015-5856

台灣地區隱沒帶地震愛氏震度地動預估式之建立與應用

title: 台灣地區隱沒帶地震愛氏震度地動預估式之建立與應用 abstract: 摘要：合適的地動預估式不僅可以瞭解一地區遭遇地震時之地動衰減特性，並可以用來預估特定場址之地動值大小，提供工程耐震設計之用。本研究以愛氏震度作為地振動指標，針對此進行地動預估式之研究。愛氏震度為地震歷時紀錄之加速度平方後積分所得到的地動參數，是一個可以包含地震波之振幅、頻率內涵和持續週期之地動參數。相關研究顯示愛氏震度大小與許多地震災害程度有相關性，如長週期建築物之破壞、土壤液化及地震引致之山崩災害等。本研究以中央氣象局自由場強地動觀測網計畫（TSMIP）豐富強震資料，考慮場址特性、震源機制以及地體構造特性差異外，增加場址變數Vs30，採用混合效應模型及最大概似法進行非線性迴歸分析，完成適合台灣地區之隱沒帶地震愛氏震度地動預估式。研究成果顯示，隱沒帶地震與地殼地震之愛氏震度地動預估式相比，結果顯示隱沒帶地震所推估之地動值明顯地較高，顯示地殼地震與隱沒帶地震之愛氏震度衰減情況並不相同出版者：台灣: 財團法人中興工程顧問社出版日期： 2014-10 出處：中興工程, 2014-10, p.033-043 資源來源： Alma/SFX Local Collection 識別號： ISSN: 0257-554X

山崩潛感於不同分析單元下的差異

title: 山崩潛感於不同分析單元下的差異 abstract: 摘要：在山崩潛感分析的發展過程中，曾有許多不同的基礎分析單元被使用，其中，網格單元的使用率占絕大多數，斜坡單元次之，其餘單元僅在早年被用過。山崩潛感所使用的資料，如地形資料等其型態多數為網格，網格單元之資料處理過程較為容易，向量資料相較之下工序較多。每一斜坡單元所占面積較大，數量上相對於網格單元少得很多，然而樣本數量的多寡影響分析結果甚鉅，使得網格單元模式穩定性較高。
本研究以位於烏溪中下游的6 幅1/250,00 圖幅作為研究區，使用羅吉斯迴歸分別針對網格單元及斜坡單元進行山崩潛感分析，分階段探討兩種分析單元於廣域山崩潛感分析的優缺點。分析結果顯示，在各階段兩分析單元各有其優缺點，雖然網格單元之模式於訓練成果或驗證結果皆優於斜坡單元之模式，但斜坡單元模式於區域規劃、工程選址及防災決策應用上具有優勢出版者：台灣: 財團法人中興工程顧問社出版日期： 2016-07 出處：中興工程, 2016-07, p.027-035 資源來源： Alma/SFX Local Collection 識別號： ISSN: 0257-554X

Triggering and runaway processes of catastrophic Tsaoling landslide induced by the 1999 Taiwan Chi-Chi earthquake, as revealed by high-velocity friction experiments

title: Triggering and runaway processes of catastrophic Tsaoling landslide induced by the 1999 Taiwan Chi-Chi earthquake, as revealed by high-velocity friction experiments abstract: 摘要： Pliocene sedimentary rocks of about 130 Mm3 in volume slid along bedding planes dipping by 14°, with an average speed of about 35 m/s, during the Tsaoling landslide. We conducted friction experiments to reproduce the initiation processes of this landslide, by idealizing landslide movements during the earthquake as accelerating/decelerating motion. Experiments were done on shale from the field, at 3 MPa normal stress corresponding to the overburden pressure. Results indicate that the accelerating/decelerating motion causes weakening and strengthening at each oscillation cycle and results in overall slip weakening which can be approximated as an exponential slip weakening. Behaviors during oscillatory slip are fairly similar to those during sliding at constant slip rates. Newmark analysis with measured frictional properties reveals that the landslide can be triggered with wet gouge properties, but the landslide motion stops with parameters for dry shale gouge. Delayed initiation of the landslide is consistent with a survivor's witness. Key Points High‐velocity friction experiments reproduced earthquake‐induced landslide 其他題名： Geophys. Res.
