摘要

在车辆运行过程中，轮胎磨损和道路磨损产生的有害排放物会释放到空气中。道路粉尘颗粒含有致癌物质。用便携式激光粒子计数器测定了道路粉尘中颗粒物的数量和分布。在沥青路面上，75%的有害排放物是0.3µm的颗粒物。在土路上，95%的排放来自小于1微米的颗粒。无论交通强度如何，大分量有害排放物的排放量都不超过1.5%。距巷道30 m处，有害物质浓度降低5 - 7倍。到2030年，车里雅宾斯克的车辆数量将增加25%。这将使轮胎和道路磨损产生的有害排放物每年增加20吨。

Measurements of Tire and Roadway Dust Particulates in Chelyabinsk

Harmful emissions from tire wear and roadway wear are released into the air during the operation of vehicles. Particulate road dust contains carcinogenic substances. The amount and dispersion of particulate matter in road dust was determined with a portable laser particle counter. On asphalt roads, 75% of the harmful emissions were 0.3 µm particulate matter. On dirt roads, 95% of emissions were from particles less than 1 µm. The amount of large fractions of harmful emissions did not exceed 1.5%, regardless of traffic intensity. 30 m from the roadway, the concentration of harmful substances reduced by five- to sevenfold. By 2030, the number of vehicles in Chelyabinsk will increase by 25%. This will increase the amount of harmful emissions from tire and roadway wear by 20 tons per year.

期刊介绍： World Earthquake Engineering was founded in 1985 and is now a quarterly journal. It is an academic journal in the field of earthquake engineering under the supervision of China Earthquake Administration (CEA), and co-sponsored by the Institute of Engineering Mechanics of China Earthquake Administration (IEMCA) and the Chinese Society of Mechanics (CSM). The journal aims to introduce the latest research results in the field of earthquake engineering at home and abroad, to promote international academic exchanges in the field of earthquake engineering, and to serve China's seismic prevention and anti-seismic work. China Association for Science and Technology (CAST) selected China's high-quality scientific and technological journals in different fields for its hierarchical catalogue, and the journal was selected as T2 level (internationally renowned journals) of earth science and geophysical journals. Outstanding journal for the implementation of the CAJ-CD Code in the implementation of the Chinese Academic Journals (CD-ROM Version) Retrieval and Evaluation Data Specification (CAJ-CD Code) in the evaluation of excellence activities; included in the cultivation bank of Heilongjiang Province's high-quality journal projects.
