Experimental Study On Mechanical Properties Of The Sacked Cemented-soil And The Masonry Things

The sacked cemented-soil is a kind of masonry stuff which made cemented-soil mixing intensive to a scale and enclose it to the wove wack..It is a sort of new fashioned constructional material which driving at slope protection and protective covering.The sacked cemented-soil give full play to merit of the soil cement and sacking sandy.It have merit of higher intensity, better whole performance,masonry convenience,quicker construction velocity,lower construction cost,protecte environment,slope type hardiness.It possess best economic benefit and social benefit as well. The sacking earth or sand had been extensive used as slope protection or retaining wall,but mostly used in temporary project.The sacked cemented-soil has successful example use at the practice engineering as slope protection or retaining wall.It didn't extensive in permanent works.The theory and experimental study laging of the sacked cemented-soil is that why doesn't extensive in permanent works.Using the sacked cemented-soil at the engineering as slope protection or retaining wall ,it has a import guideposts namely for internal stability besides the compressive of the cemented-soil.So, The research on the interface behaviour between the sack is very inport.This article through the medium of simulation The sacked cemented-soil's curved face touching proceed direct shear test on the interface performance.1) Throughthe simulation test,Discuss the interface behaviour and the failure mechanism which under the contact of curved face;2)Discuss the gaining strength'change law under the contact of curved face; as well as the impact of cement adulterate quantity, age on the sacked cemented-soil' shearing strength;3)Analyse the reaction mechanism of the sacked cemented-soil under the contact of curved face,and ,through predigestion analysing,lodge the design formula of the snap-in force under the discretion contact of curved face;4)Experiment aim at the retaining wall of the sacked cemented-soil ,proceed analyses the subsidence on the self load actioning and the compactness in differ depth;5)Research the collapse mode of the sacked cemented-soil through proceed destructive test on the retaining wall of the sacked cemented-soil. Past the upwards research on the sacked cemented-soil,supply the theory and test gist on the rataining's engineering and construction.
