LNG环保自卸汽车在长河坝工程中的推广应用研究

Study on the Application of Environment-friendly LNG Dump Trucks in Changheba Hydropower Station Project

长河坝水电站大坝工程坝料运输总量大、强度高,场内交通隧道运输份额大。为减少坝料运输对环境的影响,经多方论证后尝试引进LNG环保自卸汽车,开创了水电行业LNG环保自卸汽车应用的先河。伴随其投产运行对LNG环保自卸汽车进行了动力性、燃油经济性、制动性、操控稳定性、平顺性以及通过性等多方面试验研究,为LNG汽车在水电施工行业的推广应用提供参考。

The quantity and intensity of dam material transportation in dam filling of Changheba Hydropower Station are large and a larger share of dam material will be transported through tunnel. In order to reduce the impact of dam material transportation on the environment, the LNG dump trucks are introduced after arguments, which is the first application of LNG dump truck in hydropower industry. The dynamic performance, fuel economy, braking performance, handling stability, comfort and trafficability of LNG clump trucks are experimentally studied with the commissioning of these trucks. The results will provide references to the application of LNG vehicles in hydropower construction industry.
