海湾战争是一场高技术、高强度、高消耗的现代战争,双方都投入了大量新武器、新装备、新技术,尤其是空袭和反空袭斗争十分激烈。出动飞机之多,武器装备之先进,空袭时间之长,空袭范围之广,投弹密度之大,战争消耗之惊人,是第二次世界大战以来所仅有的。这场历时四十二天的战争,给人们的启迪是多方面的,就人防建设和开发城市地下空间来说,有以下三个问题值得人们去思索。 相似文献

Problem, research strategy, and findings: Scenario-based planning offers the promise of enhancing local coastal management given uncertainties from shoreline dynamics and climate change. Deploying it can require substantial capacity, however, or can obscure the key policy choices a community faces. We set out to develop and test a simple, decision-centered approach to scenario-based planning as a way to improve local management of coastal shorelands through master plans, focusing on coastal hazard mitigation. We also looked for ways to use basic spatial analysis techniques and off-the-shelf data sources that could be manipulated to generate meaningful and reasonably accurate analyses. We find the simplified and decision-centered methods we have developed can provide useful information for local decision makers. We also find the quality of the master plans adopted by two partner localities that used our scenario-based planning methods substantially exceeds the quality of comparison plans with regard to coastal management.Takeaway for practice: Using simplified, decision-centered, scenario-based planning methods can facilitate enhanced hazard mitigation analysis and policy adoption in local master plans. Those methods necessarily will and should be tailored to the unique political and physical conditions of the community, as demonstrated by the leadership provided in the localities studied here. 相似文献

沉降变形与卸载标准是铁路路基堆载预压的主要问题。针对处于沿海滩涂软土路基之上的铁路专用线,采用插塑板与堆载预压相结合的方案进行地基处理,开展了大量的表层沉降、孔隙水压力、分层沉降等观测项目。据实测资料,总结分析了路基表面的沉降规律,并考虑了路基分层沉降与孔隙水压力的变化规律,全面地揭示了整个路基地层的沉降变化特征,运用双曲线合理地预测了工后沉降,且推算出路基整体的固结度,采用工后沉降与地基固结度建立卸载时机判别标准。为堆载预压的卸载时机判别标准研究提供了一种新的思路。 相似文献

合理确定人口疏散比例是进行人防工程需求分析的关键,人防工程规划应该把户籍人口作为人口基数。为保证人坊规划在城市空司布局上能与总体规划相衔接,应结合行政区划进行人防防护分区规划。人防工程建设应与城市地下空间开发相结合,人防工程建设总量的确定应根据过去的人防工程发展速度进行预测。编制人防规划必须有强制性条文的内容,以弥补人防法规的欠缺。 相似文献

Performance evaluation and safety assessment of a buffering stormwater drainage system (BSDS) for a low-lying area are discussed in this paper. Unlike a conventional pump drainage system, the BSDS, which drains stormwater runoff of a low-lying area to a nearby channel system through underground conduits with gravity, and then buffering peak flows with the storage capacity of a channel system, will discharge stormwater to rivers outside the low-lying area with pumps or flood gates if necessary. This kind of drainage system is considered to be environment friendly and economic both in terms of capital cost and operating & maintenance expenses. To investigate the design parameters and evaluate the performance and safety of BSDS, a hydraulic model coupling the conduit systems and a channel system was developed in this paper, and a case-study approach based on field investigation and simulation test was used. Moreover, the design requirements for safety of BSDS were drawn through a simulation test. 相似文献

This paper reviews the contribution that can be made to land-drainage and flood-defence practice by consideration of the sediment transport system of river catchments. It also outlines the problems posed by not monitoring sediment transport over wider and longer time and space scales than are conventionally adopted. The contribution made by geomorphology to this aspect of river management is identified, and examples of its application to flood-defence problems are given. 相似文献
