This　paper　describes　an　application　for　microbial　induced　calcite　precipitation　(MICP)　on　the　cementation　of　shale　soils　for　ground　reinforcement　in　cold　regions.　The　micro　and　macrostructures　of　the　cemented　body　were　characterized　using　scanning　electron　microscopy　(SEM)　and　X-ray　diffraction　(XRD)　imaging　techniques.　The　results　showed　that　MICP　can　cement　shale　particles　effectively　with　a　significant　amount　of　generated　calcites　on　the　surfaces　of　particles.　Cementation　tests　for　shale　soils　with　various　size　distributions　indicated　that　shale　allows　easy　deposition　of　calcium　carbonate　(CaCO3)　crystals　with　high　bond　strength.　The　optimal　particle　size　distribution　to　achieve　high　strength　should　include　particles　with　good　grading　in　all　size　ranges.　To　investigate　the　damage　characteristics　of　the　cemented　body　in　response　to　freeze-thaw　weathering　processes,　tests　were　carried　out　on　samples　with　four　different　water　contents.　The　apparent　damage　characteristics　of　the　cemented　body　and　the　development　of　pores　and　fissures　due　to　freeze-thaw　weathering　were　studied　in　detail.　The　results　showed　that　the　freeze-thaw　failure　of　the　cemented　body　was　a　physical　process　occurring　when　the　frost　heave　force　exceeded　the　bond　strength　created　by　MICP.　When　the　number　of　freeze-thaw　cycles　exceeded　a　certain　threshold,　large　areas　of　damage　were　formed,　leading　to　significant　spalling　on　the　surface　of　the　cemented　body.　More　severe　spalling　damage　was　observed　for　cases　with　higher　water　content　and　more　numbers　of　freeze-thaw　weathering　cycles.　The　T-2　spectrum　curves　of　the　cemented　body　showed　that　the　development　of　small　to　medium　size　pores　was　dominant　for　the　cemented　body　with　low　water　content　and　for　high　water　content,　the　continuous　expansion　of　large　size　pores　was　dominant.　In　addition,　this　feature　was　consistent　with　the　observations　from　magnetic　resonance　imaging　(MRI)　images.
