Abstract

The invention provides an urban rail transit elevated line planning method and device based on a sound environment, and relates to the technical field of urban rail transit. The method comprises the steps that key parameters are acquired, wherein the key parameters are characteristic parameters obtained after urban rail transit elevated line characteristic simplification, and the key parameters are composed of the train speed, the gallery width, the barrier type and the running density; according to the train noise correction amount, the urban rail transit elevated line is planned, key parameters obtained after complex correction parameter simplification are adopted, and planning workers can conveniently achieve rail transit elevated line planning optimization work.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method and device for urban rail transit overhead line planning based on acoustic environment. Background technique [0002] In today's technological progress and rapid development, noise pollution is a very common pollution that has a great impact on people's lives. At present, in the planning and design of various rail transits, the noise generated by rail transits, that is, the acoustic environment impact of rail transit overhead lines, is taken as an important indicator of line planning and design. At present, for the planning of urban rail transit elevated lines, the correction parameters involved are relatively complicated, and the planning process is relatively cumbersome, which is not conducive to the actual operation of planning staff. Contents of the invention [0003] The object of the present invention is to provide a method and device for urban rail t...
