內傾式曲線月台建築界限加寬修正值計算

Calculation of the Corrected Values for the Inward Tilting Type Curved Platform Track Clearance Extension

本文探討鐵路站場中曲線月台內傾淨空修正值之計算流程。考量行車安全以及旅客上下車之安全，鐵路規章對月台與列車之相對淨空尺寸皆有規定。但是近年來許多現場施工經驗顯示，鐵路規章對曲線月台與列車之相對淨空尺寸修正值之規定並不足夠，於軌道舖設完成後，導致列車內傾產生入侵月台段建築界限而擦撞月台之現象。針對內傾式月台淨空量計算，本文將以臺鐵汐科站東二主正線及高雄計畫將新建之鼓山車站東正線作為工程實例，分別使用鐵路規章、概算式及精算式計算月台淨空量，並加以比較討論，希望討論結果能夠提供日後曲線月台工程設計施工之參考。現場施工經驗顯示，本文精算式與概算式計算成果皆可符合規章之規定及現地之要求。

The thesis aims to explore the calculation process for the correctedvalues of the inward tilting type curved platform clearance in station compounds.Considering the safety of operations and passengers, the railway- related laws and regulations have laid down the specifications for therelative clearance between the platform and trains. However, in recentyears, issues addressing the insufficiency in the regulations set tostandardize the clearance between the curved platforms and trains havearisen from the experiences of on-site construction. Such insufficiencyhas caused the trains to tilt towards the platform and encroach upon thetrack clearance after the tracks are laid, and in some cases, the trains havecome into contact with the platform structure. Targeting the calculationfor the inward tilting type platform clearance, this thesis will conduct acalculation of the platform clearance based on the rough estimation andprecision calculation methods set forth in the railway related regulations forthe actual cases of the Taiwan Railway Xizi Science Park Station East-2Main Line and the new Kaohsiung Gushan Station East Main Line andinitiate a discussion on the comparisons of the results. The discussionsare expected to provide valuable references for design and construction ofcurved platforms in the future. Experiences of on-site constructionindicate that results of the precision calculation and rough estimation arecompliant with the regulations and site requirements.
