Ivanchenko V. Pressuremeter during cementation quality assessment base for drilling-mixing technology

Object - soil-cement base testing; goal - bases compressibility determination, reinforced by vertical elements with pressiometer tests help; methods - experimental with reinforced base characteristics determination by pressiometer and stamp tests; theoretical and numerical modeling of pressiometer testing process, base, reinforced by soil-cement elements (SCE); novelty - the first time by numerical and field experiments the data of the bases compressibility are obtained, reinforced by vertical SCE pressiometer scheme tests; the dependence of the base compressibility value from the SCE percentage in the total soil volume is established; method for soil-cement base compressibility testing is improved; results - principles of the pressiometer design schemes tests are developed; by numerous experiments, the optimal size of the pressiometer probe is established; the first time the solution of calculation complex problem "pressiometer probe - base" is obtained; a series of pressiometer tests in different soils in order to compare the data of numerical experiments with full-scale tests is performed; the methodology of soil bases compressibility characteristics determination; industry - building
