Study On Compressive Properties Of Tibetan Stone Wall

Tibetan dwellings rubble masonry buildings is built by rubble stone masonry wall as the main bearing member of housing,it has very significant region and a long history.Tibetan dwellings is one of the traditional dwellings in our country which is the main representative of architectures,due to the different kinds of stones in the wall,the masonry method and bonding materials.Tibetan dwellings form a rich and colorful architectural features.Because of having local materials,high compression strength of stone,long life of the structure and so on,Tibetan dwellings currently is still widely retained and record local construction wisdom and culture and have high research value.The construction technology of Tibet dwellings is unique,but the masonry of the house is based on the experience of the local craftsmen.it has a greater randomness,which makes the structure of security risks exist.Existing stone houses in the normal use of the process appeared a variety of quality diseases,they make compression bearing capacity of the wall decreases,and the overall housing bearing capacity and stability are greatly weakened.The in support of the Tibetan residential seismic safety of repair and reinforcement application technology research "project,to hair stone carried out theoretical and Experimental Research on,and then put forward the improved technology of hair stone compression properties of Tibetan vernacular.Through field research conducted in Tibet rubble masonry early,grasp the hair stone masonry materials,laying process and wall structure of relevant information,refer to the relevant literature and summarize them,on the basis of the carried out experiment research on compression strength of rubble masonry,wall analysis by force deformation and failure characteristics,discusses the failure regularity of the wall,and then to the results and conclusions of this as the basis,proposed stone compression performance improvement of;and through theexperiment verify the validity of the improved technology.The details are as follows:(1)According to the investigation and literature research,the structure of rubble stone walls are analyzed in theory from material properties,construction technology and regional culture in this paper.(2)Based on the investigation datas,this paper carries out compression tests on the specimens,the deformation and failure law are analyzed under the axial load and the failure characteristics are discussed.(3)Based on the results of compression test and the failure characteristics of rubble stone walls,The improved technologies of stone compression performance are proposed,and the improved technologies are verified the validity through the test.(4)The effect of different stone Numbers on the compressive strength of stone wall under the same content of yellow mud and the same content of yellow mud was obtained.The deformability and cracking characteristics of stone wall with different number of stones in each group were analyzed.
