A Study of High-Filled Slope Stability with an Application of Geogrid Reinforced Retaining Wall

[[abstract]]本研究「加勁擋土牆應用於高填土邊坡穩定探討」係為苗栗縣竹南鎮某區段徵收開發區邊坡，經區段徵收、都市規劃為道路用地及公園綠地的低密度開發區，規劃單位設計以柔性加勁格網擋土牆應用在高填土邊坡。 章節開始緒論概述台灣佔有70%以上丘陵地，在相關公共建設方面，無可避免破壞原地貌，然邊坡保護之重要性更顯彰顯。經歷三十多年監造工作，遇問題想求知是我研究的動機，其目的在於檢視以往所做過事的真實性。借著研究方法及步驟流程，使其探討更明朗化。 文獻回顧先從對擋土牆、加勁格網擋土牆方面的熟悉及美國普渡大學所研發的STABL-6H軟體的介紹瞭解與操作。在基地的調查方面使其周邊的環境、地質鑽探報告之參數提供軟體應用分析混凝土擋土牆、混凝土擋土牆加基樁、加勁格網擋土牆量化出數據與圖表，以上述三種工法比較及確認該設計方案的可靠性。 關鍵字：地質、擋土、邊坡穩定、STABL。[[abstract]]This research project of “Stability Analysis of Stiffening Grid Retaining Wall used for Slope of Highly Back-Filled Hill” is based in the development area of certain area in Zhunan Township Miaoli County Through sectional expropriation and urban planning of roads parks and greenery for the low-density development zone the planning unit decides to use flexible stiffening grid retaining walls on the slope of highly back-filled hills In the beginning it depicts the fact that at least 70% of Taiwan is hill land This means that damage to original landscape is unavoidable in all related public construction work and accentuates the importance of slope protection program As my 30 years experience working as a construction supervisor it is in my motivation to solve such kind of problem on job site The aim is to inspect & review the reality of past projects and make the research result clear through listed methods and procedures It will started with brief introduction of retaining walls and reinforced grid retaining walls and operational analysis of the STABL-6H program developed by Purdue University of United States Research which based acquired soil parameters of geotechic investigation report regarding the surrounding environment and geological condition are analyzed by computer programs to list relevant data and charts on concrete retaining walls concrete retaining walls with piled foundation and reinforced grid retaining wall The design methods are compared and confirmed reliable through the three construction methods depicted abov
