加勁擋土結構破壞原因之案例探討 2013-09-02
 

本文蒐集近年來北台灣地區 11 起加勁擋土結構破壞案例,針對其破壞原因加以定性探討。研究結果顯示,降雨為導致國內加勁擋土結構破壞之主要天然因素,而人為因素方面則工程實踐之每一環節均與案例破壞有關,然而論其要者,則以規劃與施工之疏失較具關鍵影響,且問題癥結並非在於加勁擋土結構之特殊專業分析與設計,而係傳統大地工程邊坡穩定分析與設計之專業訓練不足。依據研究成果,本文建議應強化相關工程人員於邊坡工程之在職教育與訓練且著重成功與失敗案例之經驗傳承與累積,改善填築土料施工計價與檢驗制度,以及因應臺灣加勁擋土結構之本土特色,由材料廠商結合優秀專業團隊,以統包方式承攬加勁擋土結構之施作,方可避免爾後類似破壞之再度發生。

   
Forensic Study of a Highway Reinforced Soil Slope Failure 2011-07-12
 

 As the uses of geosynthetic reinforced structures continue to increase, the possibility of their failure also continues to grow. In recent years, more failures of geosynthetic reinforced slopes initiated by intense rainfall have been reported. These incidents were likely the effect of water being absorbed by ........

   
A complex reinforced structure applied at hilly road repair case in Taiwan 2011-07-12
 

 In the filed of geotechnical engineering,frequently soil nailing is applied to the application  of  the shallow-depth  or  medium-depth  slope  reinforcement  construction  at  cut  slope,  tunnel  linings  construction and Tie-Back strut system for deep excavation. Its theory of mechanical mechanism is through soil nails,shotcrete and bonded surrounding soils to reach the soil improvement.........

   
有限元素法於加勁擋土結構之穩定分析 2011-07-12
 

2009海峽兩岸地工技術/岩土工程交流研討會於4月14~16日在台中全國飯店舉行並圓滿閉幕。本次研討會由台灣財團法人地工技術研究發展基金會與中國建築業協會深基礎施工分會共同主辦,會議主題為『地工技術的應用與發展』。

   
WETTING-INDUCED GEOSYNTHETIC REINFORCED SLOPE FAILURE(229) 2011-07-12
 

Failures of geosynthetic reinforced soil slope (RSS) initiated by intense rainfall have been often reported recently. These incidents were likely to be the effect of strength reduction upon wetting for unsaturated fill. This paper proposes a practical approach to evaluate the probable erroneous in analysis that ............

   
生態案例說明-投83線14k+100~14k+550處大坍方災修復建工程 2011-07-12
 

九二一集集大地震誘發南投地區崩塌災害之發生,每遇颱風挾帶豪雨,各地山崩地滑災情頻傳,而投83線道路為地勢險峻、地質不良之路段,亦為崩塌災害頻傳災區之一。民國九十三年敏督利颱風造成總長約一百公尺,滑動深度約二十公尺之大規模邊坡崩塌.........

   
Behavior of Geogrids under Different Strain Level 2011-07-12
 
Geogrid material is widely used in geotechnical engineering field to construct soil reinforced structures. The Mechanically Stabilized Earth Wall (MSEW) is one of the popular earth retaining structures for slope stability. The safety of MSEW is generally determined by limited equilibrium analysis (LEA)......
   
Case study of using complex reinforced structure to repair mountain road landslide in Taiwan 2011-07-12
 

Taiwan is located in subtropical monsoon climate zone and on the circum-Pacific seismic belt. Its geographic position is unique. Natural disasters occur frequently. Due to its young, complex and fragile geology,  bad  cementation  of  the  rock  formation  and  steep  slope  terrain,  ....

   
The influence of uniaxial tensile strain on the pore size distribution and filtration characteristics of geotextiles 2011-07-12
 

The influence of uniaxial tensile strain on the pore size distribution and filtration characteristics of geotextiles is studied. An experimental apparatus was designed and used to conduct tests for pore size distribution, flow rate through the geotextiles and the gradient ratio. Four geotextiles made of .........

   
The Geogrid Stiffness from Small to Large Strain under Tensile Loading 2011-07-12
 

The South China Sea throughflow begins at the Luzon Strait as an intrusion of the Kuroshio. At the  present  time,  there  are  insufficient  in  situ  measurements  either  to  estimate  accurately  the transport loss or to provide a clear picture of the Kuroshio pathway at the Luzon Strait. In this study,  we  use  newly  available, ........
