Research And Application Of Key Techniques For Reliability Evaluation And Reinforcement Of Raw Soil Buildings

Raw soil house is a very important part of the traditional house in our country.The house built with raw soil has many natural advantages of modern concrete or brick-concrete structure house,for example,the cost of raw soil house is very low,the construction technology is very simple,the construction material is taken from the local soil material,the whole construction process will not pollute the environment,and the house itself can be used twice.The heat preservation and heat insulation performance of raw soil houses is superior,so there are still a large number of rural areas in some areas of our country.There are also some shortcomings in raw soil houses,such as weak joint connection,insufficient strength of members,poor seismic performance and so on..In order to inherit the traditional culture and continue the local style and features,it is necessary to strengthen and transform this kind of raw soil house.This paper focuses on the seismic performance of raw soil houses in our country,focusing on the research of arch kiln houses,from the investigation of raw soil houses,the construction mode of raw soil structures,the reinforcement mode of raw soil houses,the finite element analysis of raw soil houses,the seismic performance tests of raw soil houses and so on.The main work and results are as follows:1.Summarize and summarize the construction modes of the native soil structure houses in the villages and towns.From the aspects of material selection,structure system,foundation,wall and roof system,give the weak parts of the native soil structure houses in the villages and towns,and provide technical support for the construction of the native soil structure houses in the villages and towns.2.The reinforcement test of the raw soil structure houses in villages and towns is carried out,and the full-scale model test is made,which provides technical support for the study of the seismic reinforcement of the raw soil structure houses in villages and towns.3.the experimental study on blasting vibration of villages and towns with raw soil structure is carried out.A hundred blasting tests were carried out on a full scale model,and a large number of real and effective test data were obtained.This paper studies and analyzes the dynamic characteristics of the raw soil house under earthquake and the seismic basis of the rural raw soil house.4.The full-scale blasting seismic test of rural raw soil house is carried out,and hundreds of blasting tests are carried out on the typical raw soil house.It is found that the reinforcement measures can work well with the building,and the reinforcement effect is good.
