    • 軌道運輸為國內重要且不可或缺的運輸骨幹，近年來多起軌道挫曲導致列車脫軌事故，提升道碴側向阻力為防止軌道挫曲最直接且有效之方法，本研究期望透過現地實驗與材料試驗，找出提升道碴側向阻力的可行對策。
    本研究於臺鐵正線選取不同條件之113個量測點，以Single Tie Push Test方法量測道碴側向阻力並記錄其軌道斷面，並於每個點位採集50公斤道碴進行篩分析、卵石率、扁平率、洛杉磯磨損率、吸水率等試驗，並將以上參數以逐步迴歸分析找出較為相關之影響因素與阻力預估式。
    研究結果顯示，影響道碴側向阻力值之因素，由影響大到影響小依序為: 卵石率、1.5吋篩殘留率、相對路肩堆高、0.5吋篩殘留率。提高道碴側向阻力之可行對策為: 降低道碴材料卵石率、增加軌道路肩堆高、篩分析標準內增加1.5與0.5吋篩分析道碴材料、提高道碴材料中大理岩之比例。
    而本研究經由逐步迴歸得到之道碴側向阻力值預估式為: 道碴側向阻力預估值= 367.28(卵石率) – 8.58(卵石率)2 – 1265.34(SQRT(卵石率)) + 4.53(相對路肩堆高) + 10.85(1.5吋篩殘留百分率) + 24.03(0.5吋篩殘留百分率) + 1114.868。

    Railway transportation has become a vital part of Taiwan’s transportation. There was several railway accident cause by rail buckling. The most effective way of preventing railway buckling is to improve lateral resistance of ballast railway. This study focus on how to improve lateral resistance effectively.
    The study chosed 113 measuring points, using single tie push test to measure lateral resistance. We also collected 50 kg ballast for each measuring point simultaneously for material test. After collecting these parameters above, using regression analysis to find parameters that really affect lateral resistance.
    The result of the study shows that parameters that really affect lateral resistance from high related to low related are: cobblestone rate, 1.5 inch sieve analysis, shoulder stack height, 0.5 inch sieve analysis. The study also establish a lateral resistance estimation sentence from the result of regression analysis.
