川西北安多藏式民居的结构特点及抗震性能          下载免费PDF全文

李碧雄    赵开鹏    王甜恬    刘慧军  李梁慧 《世界地震工程》2022,38(2):021-28

传统安多地区藏式民居历史悠久,建筑特色鲜明,建造材料和建造工艺相对原始,川西北地区发生的几次地震中其抗震表现参差不齐。为了提高安多地区藏民的居住安全性,本文基于现场调研和文献资料分析,全面梳理了该地区民居的结构组成和构造特点,结合九寨沟地震中安多民居的震害特点和易损性特征,剖析了其抗震性能。研究表明:该类民居的建筑结构兼具藏式碉楼和汉式穿斗木构架的特征,易损性接近砖混结构;分层建造方式削弱结构竖向整体连续性,客观上通过层间错动有助于提高抗震耗能能力;结构体系混杂、砌筑墙体强度低、节点抗震性能不佳和楼屋盖自重大是其抗震主要薄弱环节。建议在保留建筑风貌的基础上优化结构体系,加强抗震连接构造,引入装配式建筑理念。  相似文献   

2000-2010年广州市住房产权管理角色变化分析     

刘望保  闫小培 《地理学报》2015,70(6)

中国城镇住房分配从再分配体制向市场化为主的分配体制转变,深刻地影响政府、单位和市场在住房产权管理角色上的变化。利用广州市老八区的"五普"和"六普"数据,从住房产权结构变化、住房产权选择和住房产权空间形态等角度,分析政府、单位和市场在住房供应、分配和空间配置等住房产权管理中的角色变化。广州市2000年以来的住房产权结构变化反映了单位退出住房供应角色、政府保障房供应力度不够、市场成为最主要住房供应主体等特征。住房产权选择影响因素表明家庭与单位、政府之间的组织联系逐步弱化,与市场间的社会联系日益成为主导,家庭生命周期、家庭收入等体现家庭与市场间的市场联系变量成为城镇居民住房选择的最显著影响变量。住房产权空间形态重构表明,2000-2010年间,中心城区单位提供的体制内住房比重大幅度下降,并逐步被体制外住房所替代,政府提供的体制内住房则向郊区或近郊区形成集聚,导致体制内外住房空间布局出现一定"倒置",住房来源过度市场化、住房供应主体变化和级差地租等因素是其重要形成原因。研究还显示,单位不再承担住房供应任务后,尽管政府在住房调控上起到重要作用,但未充分承担起住房供应任务,城镇居民住房来源"过度市场化"趋势。为此,政府应加大保障房建设力度,并在区位上力求分散、均衡和避免郊区化,以避免加重保障房社区居民居住空间和社会空间上的双重边缘化。随着城市住房市场化的深入发展,中国城市大规模的房地产开发和政府房地产调控政策的制订过程中,更应关注快速全球化、现代化和市场化背景下居民家庭结构、社会经济地位等体现家庭与市场间的社会联系的变量对居民住房选择偏好的影响。  相似文献   

Beyond anecdotal evidence: Do subsidized housing developments increase neighborhood crime?     

《Applied geography (Sevenoaks, England)》2015

While planners and policymakers have advocated the need for project-based subsidized housing, they often face the challenge of strong community opposition due to the negative perceptions of subsidized housing and subsidized households, and the fear that these developments and residents would bring increased crime. This paper aims to extend beyond anecdotal evidence by examining the impact of a popular U.S. affordable housing program, the Low-Income Housing Tax Credit (LIHTC) program, on neighborhood crime rates. We estimate the levels and trends in neighborhood crime before and after LIHTC developments, based on crime incidents data from 2000 to 2009 in Austin, Texas, using the Adjusted Interrupted Time Series–Difference in Differences (AITS–DID) approach to clarify the causal direction of impacts of LIHTC developments. Results show that LIHTC subsidized housing tended to be developed in neighborhoods where crime was already prevalent, and contrary to popular perception, LIHTC developments have a mitigating impact on neighborhood crime. These results suggest that LIHTC developments may be an effective tool for revitalizing distressed neighborhoods by ameliorating the “broken windows” problem and reducing neighborhood crime.  相似文献   

农村居民点动态演变及驱动机制研究——以江苏省宜兴市为例     

赵冰雪  夏敏  符海月 《地域研究与开发》2015,(1)

选取宜兴市为研究区,在GIS和RS技术的支撑下,对农村居民点用地的规模变化和空间分布进行分析,对引起农村居民点用地变化的驱动因素进行研究。结果表明:1农村居民点用地整体呈下降趋势,变化速度逐年减慢,主要新增来源是农用地,主要转移去向是城镇建设用地;2在地形平坦、距离水源和农用地较近的地区,农村居民点分布密集;3经济发展、人口减少、交通改善和城市化水平提高是影响农村居民点变化的主要驱动因素。  相似文献   

容积率地价修正系数实证研究     

王令超  樊鹏  李永明  李冰 《地域研究与开发》2015,(4)

以66个城市容积率地价修正系数为样本,以容积率比值和地价修正系数的关系为基础,对样本容积率地价修正系数进行归纳分析。部分样本存在标准容积率设定不规范、地价修正系数表现形式不科学、修正系数上限过低等问题。提出了编制容积率地价修正系数应注意的问题,并建议修订《城镇土地估价规程》(GB/T 18508—2014),在其中增加标准容积率设定方法、容积率地价修正系数编制方法等内容,增强《城镇土地估价规程》的指导作用,提高容积率地价修正系数的科学性和实用性。  相似文献   

居住小区容积率空间差异——以大连市为例   总被引：1，自引：0，他引：1  

李雪铭  朱健亮  王勇 《地理科学进展》2015,34(6)

以土地利用中居住小区及房屋调查数据为基础、居住小区为基本研究单元,通过GIS技术和泰尔指数模型,对大连市居住小区容积率空间差异进行实证研究。先应用GIS技术对居住小区容积率进行计算,其次将居住小区容积率划分为7个等级并对居住小区进行容积率分级,应用GIS软件生成空间分布图和等值线图,然后应用泰尔指数计算居住小区容积率空间差异测度指数,最后分析其形成原因。结果表明:1大连市居住小区容积率呈不同等级整体破碎、相同等级小范围集聚、邻近等级穿插结合的空间分布特征。2大连市居住小区容积率整体分异测度指数不高,极低和极高容积率等级的居住小区差异测度最大;全市四大区域中,中山区差异测度最大,甘井子区差异测度最小,四大区域的内部差异测度远远大于各区域之间的差异测度,是大连市居住小区容积率空间差异的显著特点。3居住小区容积率空间差异的主要原因是城市不同区位和房屋属性所形成的住宅类型指向、城市空间地貌对居住小区建设的制约、城市居住用地规划标准的宏观导向、城市地价对容积率的作用。  相似文献   

Hydrogeological aspects of groundwater drainage of the urban areas in Kuwait City     

Muhammad F. Al‐Rashed  Mohsen M. Sherif 《水文研究》2001,15(5):777-795

Residential areas in Kuwait City have witnessed a dramatic rise in subsurface water tables over the last three decades. This water rise phenomenon is attributed mainly to over irrigation practices of private gardens along with leakage from domestic and sewage networks. This paper presents a comprehensive study for urban drainage in two selected areas representing the two hydrogeological settings encountered in Kuwait City. In the first area, a vertical drainage scheme was applied successfully over an area of 1 km². The system has been under continuous operation and monitoring for more than 4 years without problems, providing a permanent solution for the water rise problem in this area. The hydrogeological system has approached steady state conditions and the water levels have dropped to about 3·5 m below the ground surface. In the second area a dual drainage scheme, composing of horizontal and vertical elements, is proposed. Horizontal elements are suggested in the areas where the deep groundwater contains hazardous gases that may pose environmental problems. The proposed drainage scheme in the second area has not yet been implemented. Field tests were conducted to assess the aquifer parameters in both areas and a numerical model has been developed to predict the long‐term response of the hydrogeological system in the two areas under consideration.
