强夯法在排水固结加固后地基工程中的应用

通过对地面变形、孔隙水压力的监测,分析了强夯施工时地基的有效变形率随夯击次数的变化规律及夯点的分布情况,以及强夯作用下土体中孔隙水压力的增长和消散规律,从而进一步找到了孔压增量与夯点距离的关系、孔隙水压力与深度的关系,及孔隙水压力的消散过程。并通过试夯验证和确定设计技术参数,施工后检验结果表明采用该法处理排水固结后地基对消除粗粒料过大的孔隙比、提高地基承载力、减少残余沉降和差异沉降都有极大的作用。

国内外城市轨道站点区域联动 开发规划与实施案例分析

城市轨道站点与周边土地的联动开发是实现二者协调发展的关键因素之一,对城市经济和交通都具有积 极作用。对国内外城市轨道站点区域联动开发进行总结分析有助于指导中国轨道站点区域的联动开发。从产权和 城市经济学视角,将轨道站点联动开发分为内外联动和上下联动两类,并进行了相关界定。分别结合日本联动开 发政策以及涩谷站数据、上海联动开发政策和打浦桥站区域数据,对内外联动和上下联动的规划和实施途径及其 在中国的适用性进行了分析。最后,参考更多经典的联动开发案例,对比分析了国内外城市轨道站点区域联动开 发的实施机制及特征;并从政策和规划设计两个角度深入阐述对中国联动开发的启示。研究结果表明,中国可采 用“政府统筹、市场执行”的模式;根据中国土地所有制度,探索“集约换使用权”“整体出让使用权”等多样 化的土地管理模式,有利于成本分担和收益共享的反哺策略;制定配套且细化的技术规范,进行立体化、多样化、 一体化衔接设计。     

宁波南站深基坑承压水抽水试验及数值分析

为降低深基坑工程设计与施工风险,对现场实际水文地质情况进行抽水试验,取得准确水文地质参数(承压含水层),建立深基坑降水三维渗流与沉降的数学模型,利用抽水试验期间监测数据对水文地质计算参数进行反演,进而对降水运行期间引起的渗流与地面沉降进行趋势预测。该抽水试验指导进行了基坑突涌性评价和实际工况运行控制,为降水运行提供依据,对类似工程的设计、施工及风险控制具有借鉴意义。

铁路绿色施工节地与土地资源保护措施评价

为了更好地促进绿色铁路建设,进而促进国家实现建设资源节约型环境友好型社会的目标,必须对施工阶段铁路的节地与土地资源保护措施进行评价。通过研究相关技术标准及铁路施工特点,建立一套完善的铁路绿色施工节地与土地资源保护措施评价指标体系。然后,利用三角模糊数层次分析法确定各指标权重,应用灰色聚类法确定评价指标体系的综合绿色等级。最后,结合实例证明三角模糊数层次法与灰色聚类法结合可以对铁路绿色施工节地与土地资源保护措施进行很好的评价,并能找出铁路施工阶段节地与土地资源保护的不足之处并进行改进。

Socially and environmentally appropriate urban futures for the motor car

In its relatively short life, the automobile has provided a level of mobility unlikely to have been feasible with a reliance on conventional forms of land based public transport. It has contributed in both a positive and negative way to the quality of life, transforming our cities, our way of life, and giving us a greater command over time and space. Concern over the undesirable social and environmental impacts has increased over time, with calls for governments to take action to reduce the automobile's dominant role. New investment in fixed-track public transport and bus priority systems together with strategies to discourage travel have been proposed to improve accessibility and to aid in cleaning up the physical environment. This paper reviews some of the issues facing society as it works to identify policies to achieve an economically and environmentally sustainabie future. There is a need for a broader set of policies to facilitate alternative land use-transport lifestyles while facing appropriate pricing signals. Some of the key issues are adjustments in the relative prices of location and transport, spatial incentives to make public transport economically viable (i.e. changing urban densities, zoning/incentive changes to allow more infill), road pricing (i.e. charging cars the economic cost of using the roads), new information technology systems (e.g. IVHS) to improve the efficiency and effectiveness of transport infrastructure, major improvements in the fuel efficiency of fossil fuelled vehicles, and alternative-fuelled vehicles (clean-air vehicles).
