对边坡工程安全系数的思考

Discussion for the safety factor of slope project

长期以来,安全系数在边坡工程稳定性分析中占有重要地位,随着工程实践的增多,边坡工程所遇到的问题也越趋复杂,以及有关理论和技术不断发展和人们的认识能力不断提高,人们逐渐认识到安全系数作为边坡稳定性评价指标的局限性.可靠性理论的兴起和发展,为边坡工程提供了更合理、更可靠的评价方法.本文从理论上对安全系数的局限性作了评述,指出以安全系数评价边坡的缺陷及其后果.并就边坡安全度及其方法、应用现状进行了初步分析,以期对建立边坡安全度评价体制有所裨益.

For long time the safety factor play an important position in the stability analysis of slope project, along with the increasing of the engineering practice, the problem that the slope project meets also tends more complex, The relevant theories and technique are develop continuously, and People＇s understanding ability raises continuously, People gradually know the limitation that the safety factor as the index to evaluate the stability of slope project. Rising and developing of the reliability, provide a more reasonable and more dependable evaluation method for the slope project. This text theoretically makes a comment on the limitation of the safety factor, points out the defect and result of evaluating slope by the safety factor, and made a first analysis to the slope safety degree and its method, and the present application, so that it can have a benefit to establishing safety degree of the slope.
