采用减振轨道结构是有效控制城市轨交振动和噪声的重要途径。概述了国内城市轨交常见的减振轨道结构类型,分析了影响轨道结构造价的几个因素。采用费用分解的方式计算特定工程条件下各类减振轨道结构的综合造价指标,对减振轨道结构的技术经济进行分析比较,提出在工程前期阶段明确落实轨道减振措施对工程投资控制的重要性。
The use of vibration reduction track structure is an important way to effectively control the vibration and noise of the city rail. The types of common rail structure for vibration reduction in urban rail transit in China are summarized, and several factors that affect the cost of rail structure are analyzed. The method of cost decomposition is used to calculate the comprehensive cost indexes of all kinds of vibration reduction orbit structures under certain project conditions. The technical economy of the vibration reduction orbit structure is analyzed and compared. It is suggested that the implementation of orbital vibration mitigation measures in the early stage of the project is important for project investment control Sex.
