This article examines the arms control logic that was applied to the only regional arms control talks that have taken place in the Middle East to date: the Arms Control and Regional Security (ACRS) working group that was part of the multilateral track of the Madrid peace process in the early 1990s. It highlights both the successes and major constraints of the ACRS talks in an effort to assess what might be relevant to the weapons of mass destruction-free zone conference proposed for later this year. In addition to the basic arms control dilemmas that will continue to challenge this conference—as they did ACRS—the article suggests that current conditions in the Middle East are even less conducive to regional dialogue than they were in the earlier period, due to the internal upheavals in several key Arab states, and the specific challenge of Iran's move to develop a military nuclear capability. 相似文献

考虑抗拉强度的含外倾结构面岩质边坡稳定性分析 总被引:1,自引:0,他引:1
当前工程设计都是将边坡失稳破坏看成整体的剪切破坏即M-C剪切破坏,基本不考虑岩土体本身抗拉强度.而岩质边坡真实的破坏应该是张拉-剪切复合破坏,不应是传统不考虑抗拉强度的单一剪切破坏模式.利用FLAC3D软件,基于张拉-剪切复合破坏准则对岩体和结构面强度参数同时进行强度折减,与只考虑抗剪强度的情况进行比较来研究抗拉强度对... 相似文献
