摘? 要：傳統(tǒng)架空剛性接觸網(wǎng)的安裝存在施工成本高、土建結(jié)構(gòu)破壞等問題，而預(yù)埋槽道的安裝方案不再需要打孔，安裝更加便捷環(huán)保。對(duì)比單槽道預(yù)埋與雙槽道預(yù)埋方案受力形式，單槽道方案中槽道同時(shí)受到拉力與彎矩，而雙槽道方案中槽道僅受到拉力作用，受力形式更簡(jiǎn)單。確定了預(yù)埋雙槽道為最優(yōu)方案，并通過強(qiáng)度校核驗(yàn)證了方案的可行性。

Abstract： The installation of the traditional conduct rail has problems such as high construction cost and damage to the civil structure. The installation scheme of the pre-buried channel no longer needs to be punched， and the installation is more green and convenient. Compared with the single-channel pre-buried and double-channel pre-embedded scheme， the single-channel scheme is subject to both tensile and bending moments， while in the double-slot scheme， the channel is only subjected to tensile force， and the force form is simpler. The pre-embedded double channel is determined as a relatively optimal solution， and the feasibility of the scheme is verified by strength check.
