我国城市的大气污染与气体能源的地下储存

汽车尾气污染已成为城市空气污染的主要来源，改善汽车的燃气已成为当务之急。液化石油气与压缩天然气应是首选能源。延用百年的地表钢罐储存，无论从规模上、造价上、还是环境保护等方面已不再适宜。地下水封岩洞储存已应运而生。地下储气库对地质条件提出了非常严格的要求。本文重点论述地下水封洞库的保证性与围岩稳定性，同时还对我国修建地下气库的前景作了展望。

DISCUSSION ON AIR POLLUTION IN MAIN CITIES OF CHINA AND UNDERGROUND STORAGE OF GAS ENERGY SOURCE

Because the automobile tail gas has been the main source of air pollution in the main cities of China, the improvement of gas fuel will be emergency. Now the best choice for reducing the air polution is using liquefaction petroleum gas to replace the old fuel oil. But the steel tank for storing gas, used for a hundred years, has not been apropos in dimension, cost and environment protection, so the underground water curtain grotto storage is emerged with practice. Because the geological condition for gas storage under ground is very austere and important, the authors emphasize the safety of underground water curtain and the stability of surrounding rocks, then, look forward to the future of building underground gas storages in China.
