日本和中国在发展隧道有关的问题所不同的是地质条件。日本群岛是太平洋海底造山运动形成的。在日本地层中温泉特别多,听说中国地震较少,但日本处在地震带上,地震频繁,其程度每天达数次,甚至还有强烈地震。所以日本地层不稳定,处在第三纪地质构造上,仍处在地层构造活动中,火山活动非常频繁,故日本的地质复杂。山的高度海拨3000多米,日本山地面积比较多,占全国总面积的八成以上,并且平原地带被山分
The difference between Japan and China in developing tunnel-related issues is geological conditions. The Japanese archipelago is formed by the Pacific submarine orogeny. There are a lot of hot springs in the Japanese strata. I heard that there are fewer earthquakes in Japan, but Japan is on an earthquake belt and the earthquakes are frequent, reaching several times a day, and even strong earthquakes. Therefore, the stratum in Japan is unstable and is located in the Tertiary geological structure. It is still in the stratum tectonic activity. The volcanic activity is very frequent, so the geology of Japan is complex. The height of the mountain is more than 3,000 meters above sea level, with more mountainous areas in Japan, accounting for more than 80% of the total area in the country,
