碩士 / 國立臺北科技大學 / 土木與防災研究所 / 95 / The biggest special features of Taipei MRT, lie in it to have no the orbit system of steel rail stretch and shrink joint for the only whole lines in the world, nevertheless, be electricity allied the car circulate still keep producing the noise that size don''t wait for, and the noise then influence one of the important factor of quality of the mass transit conveyance.So this research mainly aims at currently orbit noise to improve of have the initiative sequence and road segment, thorough study, and look for more for the reasonable and apply of whet a track row preface.
This research main of research the content aim at the system noise of the orbit conveyance namely it become grind to judge because of carrying on, and through analysis valuation, the draw-up derails the prevention and cure counterplan of orbit noise, and to part prevention and cure the result measurement of counterplan do an initial analysis ratio to, distinguish a counterplan and become because of theoretically and the result ratio on the actual situation to with provide the best project of noise prevention and cure.
This research looks back the research cultural heritage that the related noise improves to also inquire into the improvement current conditions of mass transit noise in Taipei first to is the background data of the follow-up research, increment to the improved understanding of the steel rail noise, in addition to steel rail noise of become because of analysis and whet track frequency the subject of the both side to make a thorough study, and build up a noise improvement a need comprehensive index sign.Mass transit in Taipei operates currently although the route be divided into medium carrying capacity and high carrying capacity however only high carrying capacity belong to a steel round track system past the origin study to take high carrying capacity as range of research.
The noise improvement need synthesizes the establishment of index sign, is the influence factor which brings orbit noise to meeting to make a study first, again collect an actual measurement data application to return to seven modes of returning the orbit noise of the way establishment, part 2 then makes use of the way of expert''s questionnaire, applying the technique of Delphi-AHP, begging to take seven powers of noise factors
