In order to reduce the risk of slope stability evaluation due to the fuzziness of calculation parameters, a finite element analysis method of slope stability based on fuzzy statistics is proposed. Based on the principle of quasi-static method and with the help of the finite element software COMSOL multiphysics, this paper studies the stability of the gravel soil accumulation rock slope under the action of different seismic acceleration. By analyzing the displacement, plastic zone and safety factor of the rock soil slope, the stability of the rock soil slope is analyzed. The research results show that the fuzziness of mechanical parameters of rock and soil slope will lead to the fuzziness of position displacement and stress analysis results of rock and soil slope, and the analysis of rock and soil slope with the method of fuzzy finite element analysis can strengthen the comprehensive understanding of position displacement, stress and safety of rock and soil slope by engineers and technicians, and reduce the stability of rock and soil slope due to the fuzziness of calculation parameters to a certain extent Evaluate the risk qualitatively.
Con el fin de reducir el riesgo de evaluación en la estabilidad de taludes debido a la falta de claridad de los parámetros de cálculo, en este estudio se propone un método de análisis de elementos finitos con base en estadísticas difusas. Basado en el principio del método cuasi-estático y con la ayuda del software multifísico de elementos finitos COMSOL, este trabajo estudia la estabilidad del talud de roca con acumulación de grava en suelo bajo la acción de diferentes aceleraciones sísmicas. Al analizar el desplazamiento, la zona plástica y el factor de seguridad, se analiza la estabilidad del talud del suelo rocoso. Los resultados de la investigación muestran que la falta de claridad de los parámetros mecánicos de la pendiente de la roca y del suelo conducirá a la falta de claridad del desplazamiento de posición y los resultados del análisis de tensión de la pendiente de la roca y el suelo. El análisis de la pendiente de la roca y el suelo con el método de análisis difuso de elementos finitos puede fortalecer la comprensión integral del desplazamiento de posición, el estrés y la seguridad de la pendiente de la roca y el suelo por parte de ingenieros y técnicos, y reducir la estabilidad de la pendiente de la roca y el suelo debido a la falta de claridad de los parámetros de cálculo y, hasta cierto punto, evaluar el riesgo cualitativamente.
