【 摘 要 】

Injection applications with injection material types such asbentonite,rheocem, rheobuild1000,bentonite+rheocemwasmade and the effect of the injection on soilconsolidationsettlement was experimentallystudied. Asampleof naturalsoil, whose geotechnicalcharacteristics are known to beweak, was analyzed to determineitsbasicphysicalproperties and the sample was injected with mixtures preparedwithnaturalbentonite,rheocem650andrheobuild1000. Settlementvaluesofthesesamplesunderdifferentloadswereexperimentallydetermined andsettlementvalues ofthe naturalsamplewere taken asreferencevalues.Settlementvaluesfordifferentloadsobtained fromtheexperimentswere comparedwith each other. When reference valuesfor all loadsonnaturalsamples are taken as (100%), it was seen that the average settlementvalue ofbentoniteinjectedsampleswas 47.19% higher compared to thesettlementvalues of the natural sample, the average settlementvalue ofrheoceminjectedsampleswas 18.51% less compared to thesettlementvalues of the natural sampleandthe average settlementvalue ofbentonite+rheoceminjectedsampleswas 36.12% less compared to the settlement values of the natural sample.
