洞穴——从微中子研究到地下空间规划 被引量:1

作者 pierre duffaut 陈燕秋 《国际城市规划》 2007年第6期41-46,共6页
微中子研究需要很大很深的洞穴,以便在没有太多宇宙射线噪音的情况下捕获重要事件。大型的自然洞穴往往出现在喀斯特石灰岩地区,少数大型洞穴也会出现在矿区,而民用洞穴则被广泛用作发电站、火车站、仓库及其他用途。应力控制被认为是... 微中子研究需要很大很深的洞穴,以便在没有太多宇宙射线噪音的情况下捕获重要事件。大型的自然洞穴往往出现在喀斯特石灰岩地区,少数大型洞穴也会出现在矿区,而民用洞穴则被广泛用作发电站、火车站、仓库及其他用途。应力控制被认为是在洞穴深挖中消除巨大应力的普遍方法。如果能够在大型洞穴使用应力控制方法,我们就可以建造安全的洞室来进行微中子研究;从另一方面来讲,大而浅的洞穴也能解决城市规划的很多问题。 展开更多

The case of the Malpasset arch dam failure in 1959 has been widely exposed in scientifc and technical forums and papers.The focus here is on the many traps which have confused the whole chain of bodies and persons involved,owner,designer,geologist,contractor,up to the state management offcers.When the frst traps were hidden inside geology,many more appeared,as well geotechnical,technical,fortuitous,and administrative.In addition to such factual factors,human and organizational factors may be today easily identifed,when none of them was yet suspected.Both dam safety and rock mechanics benefted from the studies done since the Malpasset case,most of them within one decade. 展开更多
