چکیده
Rocky slopes are vulnerable to landslides and mudslides, which pose a major threat human life property. Research is being conducted improve the adhesion between soil minerals by mineral-solubilizing bacteria manage scientifically develop novel methods for slope greening. From of Nanjing Mufu Mountain’s weathered rock walls, we isolated various bacteria. During bacterial solubilization test, discovered that some could enhance adherence minerals; therefore, selected three (NL-7, NL-8, NL-11) with higher performance further investigation. Controlled experiments were used investigate effects on characteristics (soil moisture content, pH, exchangeable metal content) minerals. According findings, can soil’s minerals, capacity hold water, regulate solubilize release calcium, magnesium, sodium, potassium ions. A structural equation modeling analysis was performed thoroughly examine relationship The findings showed had greatest total direct positive impact most significant indirect pH mainly caused sodium magnesium Additionally, ions only indirectly affect accomplished controlling Therefore, primarily work enhancing water retention Our study effect demonstrates potential in spray seeding greening, will provide data theoretical support formation, application, promotion greening gradually form new set scientific efficient Chinese characteristics.

Instability of unsaturated soil slopes due to infiltration
It is widely known that rainfall induces a rise of the groundwater level and an decrease in matric suction (negative pore water pressure) that results in slope failure. However, in many situations where shallow failures are concerned, it has been noted that there is not much evidence of a rise in the groundwater level sufficient to trigger the observed slope failures. Instead, the failures have...
متن کاملAnalysis of Reinforced and Un - reinforced Soil Slopes using Abaqus
Assessing the strength of soil slopes and investigating the means for increasing their safety against failure are crucial in construction projects involving large soil masses. Slope stability analyses have traditionally been performed using a limit state approach. However, any presence of reinforcement or local heterogeneity necessitates the use of numerical techniques such as finite element an...

This paper investigates rainfall-induced landslides on partially saturated soil slopes using the 2011 Umyeonsan landslides at the center of Seoul, Korea. An integrated analysis of rainfall-induced landslide was carried out through laboratory tests, field tests, and numerical analysis. The results of comprehensive investigations in the Umyeonsan region demonstrate that landslide activity is clos...
