Exploration of Implementation Strategieson Housing Building Technology

Due to the sharp contradiction between rapidly developing housing construction in small-size town and quite low technological level, in this paper, the significance of setting up integrally technological system is emphasized and the suggestion that the technology should be integrated with the sustainable development, regional context and industrialization is put forward.     

Exploration of the Sustainability Design for Industrial Building

Within the domain of comprehensive architecture, the general instructive principles for the sustainability design are applicable to that of industrial building. Based on the analysis of excellent precedents, in this paper, some useful experiences are summarized. It is pointed out that the sustainability design is feasible and should be compulsive for industrial building.     

FEM on Coupled Hydromechanical Dynamic Response of Geogrid Reinforced Soil Retaining Wall

Geogrid reinforced soil retaining wall(GRSRW) is composed of panel,geogrid and soil,its coupled hydromechanical structural characteristics are increasingly emphasized in practice.In this paper,based on the characteristics of the reinforcement-soil interaction,the grogrid and soil around it with a definite thickness were regarded as a kind of composite material with strain-compatible condition.A saturated porous media model was introduced to simulate the soil and reinforcement-soil composite material hereby and the mathematic model for numerical analysis on structural characteristics of GRSRW was built up.The FEM equations were deduced from the standard Galerkin procedure,resolving these equations,we can gain the relevant dynamic response of saturated GRSRW.     

Study and Practice of Safety Grade Assessment for Large Convention and Exhibition Centre

This paper takes "how to estimate the complex security of Large Convention and Exhibition Centre effectively" as the research goal.Based on analyzing the difficulties,target system,technical constitution,probing into the architecture,safety science,and using for reference the mathematics,operational research,statistics and modern system theory and method,trying to explore establishing an evaluation methodological system,which is provided with integrated characters on subject.Based on these ways,it exerts "quality to quantity" fuzzy analytical hierarchy process(FAHP) and aims at discussing the safety grade assessment of the Chongqing International Conference Exhibition Center focusing on designing theories.The aim is to enhance the integration of design practice and safe consciousness,strengthen the building safety management,and perfect city public security system.In practice,it is also an efficient tool for favoring values of architectural environmental safety.     

废弃秸秆生物气化的实验研究

利用微生物对秸秆进行气化实验,研究表明:高浓度的VFA并不能抑制甲烷的生成,只是使甲烷存在一段休眠期。浸泡10天的秸秆,产气峰值出现快;当秸秆浸泡超过20天时,产气慢、周期长。其原因是浸泡期间生成的乙醇需要一段时间向乙酸转化;而驯化污泥做接种物,甲烷菌活性强,产气周期短。
