Jūrų uosto teritorijos ir gyvenamosios zonos triukšmo sklaidos modeliavimas taikant programą CadnaA

Abstract

Ivertinamas triukšmo lygis ir jo sklaida Klaip dos valstybinio juru uosto kompanijoje AB KLASCO. Ekvivalentinio triukšmo tyrimai atlikti 24 matavimo vietose, išd stytose zonomis imon s teritorijoje ir 6 matavimo vietose gyvenamojoje aplinkoje. Sukurus triukšmo sklaidos nuo geležinkelio transporto i gyvenamaja aplinka modeli pasiulyta apsaugos priemon – automobiliu transporto, laivu ir geležinkelio keliamo triukšmo sklidima mažinancios sienel s. Pagal pateikta metodika CadnaA programa gaunami triukšmo lygiu viršijimai imon s ir gyvenamojoje teritorijoje. Matavimu ir CadnaA programos rezultatai skiriasi apie 10–15 %. Rezultatai pateikiami triukšmo sklaida sumodeliavus pagal CadnaA programa.

The level of noise and its dispersion was evaluated at Klaipeda State Seaport enterprise of JSC KLASCO. Investigation was carried out at 24 measuring points located in the enterprise territory and at 6 measuring points in a residential area. Sources of noise are evaluated. Reasons of a higher noise level than that presented in the hygienic norms and possible causes of its occurance in the territory of the enterprise and in the neighbouring residential zone. Noise-decreasing means are suggested. From the proposed methods one can see that with CadnaA program, exessive noise levels are abtainable for the enterprise territory and residential zone. The achieved measuring results differ from those received with CadnaA program by 10-15%. The investigation results are presented as noise distribution determined with CadnaA program.
