French Visions

Architecture and the city are two major constituents of human development which, today more than ever, have to be present in the long-term. The Year of France in China is, for the first time, the occasion to present to the Chinese public a vision of the contemporary French architectural production, not only in France but also in China.     

Controversy Over China''''s Traditional Commercial-Streets

In recent years,a great number of traditional commercial streets has reappeared in China.The first attempt wasthe renovation of the kiu-Li-Chang street in Beijing.The renovation of the Liu-Li-Chang street in Beijing was proposed in 1978,with the first stage of the projectstarted in October,1980.It included the reconstruction of a 500 metre-length of street and 54 stores on both sideswith a floor space of 34 thousand square metres.The whole project was basically completed in the short period of afew years and has won acclaims from architects and planners at home and abroad,though arguments still exist.Soonafterwards,many cities followed suit with such influential ones as the traditional culture street in Tianjin,theCheng-Huang-Miao Temple market in Hefei and the Fu-Zi-Miao Temple market in Nanjing,etc.Traditionalcommercial streets have been set up not only in big cities.but also in some medium-sized and small cities.They are,of course,smaller in size and generally simpler.Some of the traditional commercial streets have been quite successful,while some have not produced good results.There has been a great argument among the Chinese planners and archi-tects on issues related to the traditional commercial street.Ⅰ,herewith,would like to express my view.     

Three-dimensional FDEM numerical simulation of failure processes observed in Opalinus Clay laboratory samples

This study presents the first step of a research project that aims at using a three-dimensional(3D) hybrid finite-discrete element method(FDEM) to investigate the development of an excavation damaged zone(EDZ) around tunnels in a clay shale formation known as Opalinus Clay. The 3D FDEM was first calibrated against standard laboratory experiments, including Brazilian disc test and uniaxial compression test. The effect of increasing confining pressure on the mechanical response and fracture propagation of the rock was quantified under triaxial compression tests. Polyaxial(or true triaxial) simulations highlighted the effect of the intermediate principal stress(s2) on fracture directions in the model: as the intermediate principal stress increased, fractures tended to align in the direction parallel to the plane defined by the major and intermediate principal stresses. The peak strength was also shown to vary with changing σ2.     

Prospect of HDR geothermal energy exploitation in Yangbajing,Tibet,China,and experimental investigation of granite under high temperature and high pressure

Hot dry rock(HDR) geothermal energy,almost inexhaustible green energy,was first put forward in the 1970s.The development and testing of HDR geothermal energy are well reported in USA,Japan,UK,France and other countries or regions.In this paper,the geological characters of Yangbajing basin were first analyzed,including the continental dynamic environments to form HDR geothermal fields in Tibet,the tectonic characteristics of south slope of Nyainqêntanglha and Dangxiong-Yangbajing basin,and the in-situ stress...     

混凝土与水泥制品行业上半年继续领跑建材工业

今年以来,全社会固定资产投资依然保持较快增长,意味着混凝土与水泥制品行业生产与经济增长的外在动力依然强劲.上半年,混凝土与水泥制品行业经济运行延续了上年平稳较快发展的态势,行业主要产品和经济效益实现平稳较快增长,继续领跑建材工业.The fixed assets investment growth remained fast in the first half of 2011,meaning the driving force of concrete and cement products production and economic growth still strong.The performance of the concrete and cement products industry maintained the momentum of the steady and rapid development in the first half of the year;the output of main products grew steadily as well as the profit making.It continued to lead the growth of the building materials industry.     

Review and Exploration of the Development of Planning for the Conservation of the Famous Historical and Cultural Cities in China

To comprehend the development of the famous histori-cal and cultural cities in China and their conservation plan-ning, it is necessary to understand, first of all, the back-ground of their history and present condition. This back-ground has taken shape in the historic development of thecities and is influenced by many complicated factors of thepresent time. To discuss these factors in simple way, theycan be summarized as follows:The impact of the historical and cultural ideas;The impact of the physical and environmental condi-tion;The impact of the present socialand economicsituation.The impact of the historical and cultural ideasChina is a country with ancient civilization. TheChinese cultural has been shaped through development, in-heritance and harmony in a history of 5000 years on the ba-sis of the ancient Huaxia Culture with the Yellow River andthe Yangtse River as the main arteries.The rising of ancient cities in China can be traced backto over 3500 years ago. China is a multinational country. Int
