摘要：在铁路工程建设中,合理的施工用水方案对水电价分析、编制概预算有着重要的影响。本文对水车地表水拉水、软管运水、自来水管运水、自行打井运水、农村自备井打井运水5个用水方案进行数学建模,得出了不同运水方案的综合运水单价函数表达式。并以2 km隧道供水为例,得出不同运距条件下投资最省的用水方案,进而形成具有普适性的用水方案优化设计方法。最后通过工程实例验证了水价函数的适用性。本文求得的水价函数表达式适用于快捷、准确地针对具体工点进行用水方案比选,得出最优用水方案,可为控制工程投资、提升编制概算的精确度提供数据支撑。

摘要：首次将EPANET模型用于施工现场临时用水设计中,用EPANET模拟现场给水管网,初步确定管径,运行后可直观显示供水管网上各点的供水压力,得出该状态下的运行费用。通过优化管网运行分析对比,得出满足用水压力和流量、经济可靠的方案。

摘要：本文描述了以南海某岛附近海域的珊瑚礁砂为基本骨料,采用不同组合,分别用海水、岛水、淡水拌养,制成不同标号的珊瑚礁砂混凝土的过程,并将其力学性能与普通碎石、河沙混凝土做了比较,为在岛礁上建造海洋工程构筑物利用珊瑚礁砂混凝土提供依据。

摘要：针对复杂工程建设项目水资源论证中的用水合理性分析难题,以北京新机场工程为例,探讨了机场运营期和施工期两个阶段的用水预测方法,并参考相关标准、规范及有关成果,基于节水标准提出了不同阶段用水定额,通过与同行业项目用水对比,分析了用水预测的合理性。结果表明:北京新机场本期工程(设计旅客吞吐量7 200万人次)运营期自来水用水量约1 000万m^3,与首都顺义机场同规模旅客吞吐量时用水量基本一致;北京新机场施工期高日用水量约为昆明机场的2倍,与两个机场的建设规模比相符。综合分析,在复杂工程可行性研究阶段采用定额法进行用水预测是可行的,提出的用水定额是较合理的,可为同类及相似的综合性工程用水预测提供参考。

摘要：The development of long linear structures such as roads, rail roads, tunnels, canals and pipelines often has unique engineering geology challenges. These include geological modeling, the identification of material strength and support factors, stability and risk issues, material excavation characteristics and the proposal of techniques for overcoming geotechnical problems, which are normally assessed as part of the conventional engineering geological investigation. An additional factor that is becoming increasingly important but is seldom included in investigations is the sustainability of the geotechnical inputs, in contrast to the sustainability of the project which is generally included. Sustainability issues revolve around the non-renewable nature of most construction resources and there is no doubt that the injudicious use of these construction materials and construction water is not sustainable in the long term: it is thus essential that the engineering geo-logical investigation should take cognizance of such issues and be adapted to provide the design engineer with the information that will maximize the sustainability options. This will also require a closer on-going relation-ship between the engineering geologist and the design engineer. This paper highlights significant sustainability issues (note that these differ from conventional environmental issues) and suggests some mitigating solutions. The sustainability issues discussed include primarily material and water usage, with some reference to energy conservation (mostly through alternative material usage and processing techniques and transportation).
