影响边坡稳定性的因素较多,而安全系数仍是目前边坡稳定性评价的重要指标,但未考虑其所涉及参数的任何变异,以致造成计算结果常有失真。实际工程中,边坡是一个具有时间属性的开放性系统,受关键性条件的制约,且具有一定的自我调整能力。因此,对于边坡可靠性研究应从内外因素两个方面进行考虑。通过分析边坡可靠性建模方法及其步骤,指出了在建模过程中应该注意的问题与应用目标。

There are many influencing factors of slope reliability,while safety factor is still the important indicator for evaluation of slope reliability at present,but it does not consider the variation of the parameters involved,causing calculation results often distorted.In practical engineering,slope is an open system with time property subject to critical conditions and has a certain self-adjustment capacity.Therefore,slope reliability research shall be considered from internal and external factors.In this paper,through analyzing the modeling method of slope reliability and its steps,the problems to be noted and target applications during modeling are pointed out.
