不同水位条件下渗渠集水能力砂槽试验与分析

通过不同水位条件下的傍河型浅薄含水层渗渠的集水量试验模拟,揭示了模拟傍河型浅薄含水层渗渠所傍河流的模拟水位高低与渗渠集水量大小的关系。采用砂槽模型进行模拟,在设计的4个特征水位的基础上进行了两组试验,并将其试验结果进行对比分析。研究表明,在一定条件下渗渠集水量的大小与模拟河流处的水位高低近似呈正比。     

Effectiveness of predicting tunneling-induced ground settlements using machine learning methods with small datasets

Prediction of tunneling-induced ground settlements is an essential task, particularly for tunneling in urban settings. Ground settlements should be limited within a tolerable threshold to avoid damages to aboveground structures. Machine learning(ML) methods are becoming popular in many fields, including tunneling and underground excavations, as a powerful learning and predicting technique. However, the available datasets collected from a tunneling project are usually small from the perspective o...     

德国农村住区更新实践的规划启示

从20世纪50年代开始,德国农村实施了土地整理、农村住区空间环境和既有建筑更新改造等一系列农村人居环境建设的实践。它对改良农业结构,对原有农村采矿土地的修复和生态重建,对保障基础设簏和公共事业用地,以及对加强整体生态环境保护等方面均起到了积极作用。这对我国当今农村人居环境建设规划具有重要启示：应进一步注重农村住区土地使用的合理配置,注重农村住区的整体景观品质与生态环境质量相结合,注重农村住区物质空间环境整体结构的完菩与提升,注重既有公共建筑和公共空间环境的再利用和功能提升,并注重农村住区既有建筑更新改造的适用技术支撑。     

Restoring the ruins: the social context of reconstruction in the countrysides of Northern France in the aftermath of the great war

The reconstruction of devastated farms, villages and market towns in northern France was not masterminded by the state or carried out by its emergency agencies, which were concerned with filling trenches, removing shells, restoring farmland and patching up ruins. Segments of French society needed to mobilize themselves to declare their losses and claim compensation from the state. Proposals by French trades unionists to bring in German building workers to reconstruct rural settlements were rejected. Instead, general purpose reconstruction co‐operatives were established, first in Lorraine and then throughout the régions dévastées. It is argued that the differing attitudes to religion and trades unionism in the countryside of northern France were reflected in the varying efforts made to effect rural reconstruction during the 1920s. The dream of international labour solidarity through reconstruction was not realized. Rather, restoration of northern France was undertaken by private construction companies, often contracted to general‐purpose co‐operatives.     

塑造活力与品质水岸——杭州市滨江区北塘河畔城市设计

随着城市回归滨水地域发展趋势的加快,如何建设具有活力和品质的城市水岸已经成为当前城市规划关注的课题。杭州市滨江区的北塘河畔城市设计以规划理念策略的创新、功能结构的明晰、交通体系的完善、公共利空间的丰富和开发控制引导,完善滨水地区的活力支撑体系;同时,通过突出滨水主题、复合利用土地、满足滨水活动需求、凝练滨水空间意向和构筑特色滨水空间形态,打造高品质的现代城市滨水地域。     

对人居环境的深层生态学思索

从深层生态学和道家学说的视角,对人居环境内涵进行更加深入的思考,认为居住发展的最高层次应该是天人合一,而天人合一的境界应该包括主观与客观两个方面,从而达到人与屋宇融为一体,屋宇与自然息息相通,自然与心智同时同在.     

南水北调工程十堰方滩乡塌岸预测评价

分析库岸再造的影响因素,结合十堰市方滩乡的库岸地质环境问题,采用典型稳定库岸坡度统计方法确定了不同岩性的最终稳定坡度值,选用坡角地质类比法对研究区的库岸再造问题进行工程地质评价,确定出塌岸带的宽度,从而指导移民规划工作。     

关于农村居民点布局模式的思考——以长株潭绿心地区为例

农村居民点是农村村民生产和生活的场所,也是农村土地利用的重要组成部分。长期以来,我国农村居民点缺乏整体上的布局与调控。长株潭绿心地区由于其特殊的自然地形条件,土地资源有限,存在农村居民点数量多,规模小,分布零散等诸多问题,文章最后根据绿心地区实际情况,建议采用新村建设型、岛状居民点、线状居民点三大布局模式。
