微生物引致碳酸鈣沉澱為一新興之地盤改良技術，應用於基礎整治、液化減緩、水土保持等大地災害防治中顯示良好成效。此方法利用天然之土壤細菌來水解尿素，並誘導碳酸鈣沉澱，結合土壤顆粒並提升土壤之力學特性與抗蝕能力。
本研究為探討MICP應用於減緩降雨引致淺層崩塌案例之可行性與適用性，先行以室內土壤力學試驗求取土壤基本物性、礦物成分、.不飽和水分特性曲線與土壤經MICP改良前後之工程性質，規劃以25%注漿率且菌液與膠結液各半之配比進行地盤改良。結果顯示改良後土體之排水摩擦角由原先 上升至 ，上升約2.07%；有效凝聚力則由原先 上升至 ，增加約83.39%，其中以凝聚力提升對於淺層邊坡土壤之剪力強度貢獻較為顯著，說明MICP相當適用於淺層邊坡地改；滲透係數經由改良後可下降約一個數量級；CPT試驗所測得表層土壤之錐尖阻抗亦有顯著增加。
隨後本研究進行未改良縮尺模型試驗，以影像紀錄與水分、水壓計確認滑坡模式，結果顯示由粉土質砂組成之 有限邊坡於高降雨強度下將呈現坡址後退式崩塌與坡頂淺層崩塌，形成一複合式破壞，同時材料高細粒料含量特性終將轉為泥流破壞，伴隨數條蝕溝；最後則利用影像紀錄、水分與水壓計和分佈式光纖感測技術比較大型邊坡於改良前與改良後之減緩淺層崩塌成效，結果顯示坡頂與坡腹土壤應變經MICP改良後已大幅減少，說明MICP應用於減緩淺層崩塌效應具有相當成效。

Applying Microbial Induced Calcite Precipitation(MICP), an emerging soil improvement technology, on the mitigation of some geotechnical hazards such as foundation improvement, liquefaction mitigation, soil and water conservation and so forth manifests an extraordinary outcome. This approach utilizes natural soil bacteria existing in soil to hydrolyze urea and induce calcite precipitation, which cements soil particles and improves the soil mechanical properties and corrosion resistance.
In order to explore the feasibility and applicability of MICP remediation in rainfall-induced shallow landslide cases, this research process started with some soil mechanics laboratory tests to obtain physical properties, mineral components, SWCC curve, and engineering properties before and after MICP treatment, 、 and included. The treatment volume for soil improvement planned to occupy 25% of the void space and the propotion of biological solution to cementation solution would be one to one .The results showed that the drainage friction angle receives 2.07% increase from to ；the effective cohesion receives 83.39% increase from 1.96 kPa to 3.6 kPa, especially the increase of effective cohesion easily facilitates the shear strength of surface slope soil up, which means MICP treatment is a suitable soil improvement method in shallow landslide cases；permeability is about ten times less than the original permeability； from CPT test, the tip resistance for the surface soil also increases significantly.
Subsequently, this study conducted an small-scale slope model test to confirm the failure behavior by images and data from water pressure transducers and moisture sensors. The results showed that a infinite slope composed of silty sand under a toerrential rainfall condition will be in from of a complex failure, which is comprised of retrogressive failure from toe and shallow failure at the crest of the slope；moreover, because the silty sand sample features a higher fine content, the failure type will eventually turn out mud flow, accompanied by several surface erosion.
Finally, large-sacled slope model tests without and with MICP remidation would be conducted in order to confirm the mitigation effectiveness in rainfall-induced shallow landslide；hence, images, Distributed Fiber Optic Sensing technology, and data from water pressure transducers and moisture sensors would be used. The results showed that after MICP treatment, the strain at the crest &middle part of the slope is considerably decreased, which signifies adopting MICP technology to mitigate rainfall-induced shallow landslides is successful.
