摘要
以抗滑桩锚固深度确定的原则为基础,针对不同的锚固段地层及不同的地基系数形式,建立了锚固深度可靠性设计的数学模型。介绍了Monte Carlo法在该模型中的应用,实例分析了常规设计与可靠性设计的异同,认为可靠性设计把计算参数当作随机变量更切合于实际,而且还能得出抗滑桩所承担的风险水平,同时即使抗滑桩能满足常规设计的条件,也未必能满足可靠性设计的条件。
Based on the definitive principle of anchoring depth for friction piles, as well as different strata of anchorage zone and form of foundation coefficient, mathematical model for the reliability design of anchoring depth was established. Monte Carlo method was intruduced into this model to analyze the similarities and differences between the conventional design and reliability design with a case. It was considered that the reliability design was closer to the reality because it regarded the calculated parameter as the random variable. It could also educe the risk level taken on friction piles, and at the same time it was considered that the friction piles might not satisfy the condition of reliability design even though they could satisfy the condition of conventional design.
