近年來電腦應用廣泛,電腦輔助設計尤其是在處理繁雜的公式計算對土木工程的設計及施工皆有很大的助益。本文以電腦輔助設計協助鐵路站曲線月臺內、外傾淨空修正值計算。考量旅客上下車之安全舒適,鐵路規章對淨空值尺寸有其規定,但鐵路規章之規定稍有不足,馬金龍等推導曲線月臺內、外傾淨空值修正計算公式,本文使用Excel軟體輔助計算內、外傾式建立一計算程式,使用者僅須輸入基本資料,即可取得計算結果。一般計算結果,大多為一些數據,為了讓使用者能夠更加了解其設計,本文使用SketchUp軟體將鐵路月臺3D立體化,從而方便設計進行現地施工。
Computer Aided design has been used widely for engineering.This paper discusses the calculations of curved platform of by using computer-aided design. The resatts of the curved platform clearance inward tilting type and outward tilting type including are calculated present program. This program is basen on Excel. The calculation procedures are from Ma. The present program are user-friendly. The user input the basic information, the results are shown. Also, the 3D view has been shown by using the SketchUp.
