| dc.description.abstract | 本論文針對永久性地錨於C-ψ土壤中，發展出一套符合設計準則要求且經濟實用之最佳化設計模式，以提供給地錨設計者參考。本文以「地錨設計準則」及FIP(國際PC 協會)中相關規定為限制式，利用EXCEL 軟體整合輸入資料，LINGO 軟體為計算工具，對永久性地錨單位寬度內最短施工總長度作最佳化設計。
在最佳化模式中考慮平時、暴雨及地震時之受力行為及允許安全係數；本研究之邊坡假設破壞面，係假設為一通過坡趾的斜平面；時下流行之擴孔式地錨，則可參考本模式於錨碇力公式上稍加轉換即可，至於臨時性地，則可於地錨容許載重之安全係數上稍加改變即可。
透過本研究之分析，可找出真正符合安全性及經濟性之合理配置。在敏感度分析方面提供了更寬廣的思考空，建議設計者可在擋土牆β值、設計加速度等方面仔細挑選組合，以符合現場環境之情況下達到最經濟最安全之需求。 | zh_TW |
| dc.description.abstract | A program of optimal model for permanent anchors with
multilevel and multiobjective function has been developed in
this paper.To achieve this purpose,this paper selects the rule
of anchor design and the code FIP requirements as constraint
conditions,EXCEL software is carried out to import data and
LINGO software to calculate the objective function that is the
total minimum length of the unit width.
In this optimal model,it considers the anchorage behavior
and allowed safety factor which including the normal condition,
torrential rain and earthquakes.This assumptive rupture of the
slope is assumed a plane that passes through the base of the
slope.About the cone-shape anchors,it can use the model but
transfom the anchorage formula. About the temporary anchors,it
also can use the model but change the safety factor of the
allowed load.
Through the analysis of this paper,it can find the rational
combination that match the economic interests and safety.
Through the sensitivity analysis model,it provide a wide
thinking space .Suggest the designer can select a rational
combination which is the β value of a retaining mall and
designed acceleration,to match the demands of the environment. | en_US |
