岩土工程

What is troublesome is not just that the idea, like other geoengineering schemes, is untested on any appreciable scale. 刺手的不只是该想法，像其他地质工程方案一样，它没有在任何可评估的范围内测试过。

Flat dilatometer test(DMT) was widely used in geoengineering to verify ground treatment effect. 扁铲侧胀试验(DMT)在岩土工程中已经获得广泛应用,尝试了用其检测地基处理的效果。

From mimicking a volcanic eruption to mirrors in space, some geoengineering schemes are pretty far out there. 从模拟火山爆发到在天空中安放反射镜，一些地球工程方案真是非常“离谱”。

Nanjing Xuanwu Tunnel,a subaqueous highway tunnel in the centre of the city is a typical geoengineering project in vulnerable environment. 南京玄武湖隧道，既在城市中心，又在水下，是脆弱环境下典型的地质工程。

Geoengineering schemes fall into two categories, corresponding to the two knobs you might imagine twiddling to adjust the earth's temperature. 地球工程的方案分为两类，不妨想像成两个可以控制地球气温的旋钮。
