【摘要】 悬锚式挡土墙是利用锚定板与悬臂式挡土墙组合而成的一种轻型挡土墙,它是由钢筋混凝土墙身、锚定板、拉杆及充填在墙身与锚定板之间的填料构成的一种复合式结构。近年来随着可靠度分析方法在结构、岩土等工程中的运用与发展,将可靠度分析的方法引入悬锚式挡土墙的设计计算中来,使其更为真实地反映悬锚式挡土墙结构的安全性。本文对悬锚式挡土墙的可靠度分析计算方法做了系统的阐述,并对其不同的计算方法做了对比计算。本文主要就以下内容进行了分析讨论：(1)对悬锚式挡土墙可靠度设计中涉及的随机变量如：内摩擦角、填土容重、基底摩擦系数和基底承载力等进行了讨论；(2)对目前常用的几种可靠指标的计算方法及在悬锚式挡土墙设计中的应用进行了讨论；(3)根据可靠度理论建立了悬锚式挡土墙的抗倾覆、抗滑移、地基承载力稳定性的极限状态方程；(4)基于MATLAB软件,利用JC法、蒙特卡罗法、最优化法编制了抗倾覆、抗滑移、地基承载力稳定性的可靠指标计算程序；(5)以延安安塞高速公路某段挡土墙为例,对安全系数法和可靠度法设计计算的结果进行对比,证明悬锚式挡土墙无论是安全系数法,还是可靠度设计法都是安全可靠的。更多还原

【Abstract】 Suspended-anchor retaining wall is a light combination walls with cantilever retaining wall and anchored plate. It is the composite structure that made of reinforced concrete walls, anchor plate, rod and filler between the walls and anchor.In recently years, with the application and development of reliability analysis in structural, geotechnical and other projects, it will be more realistic describe the security of suspended-anchor retaining wall when the reliability analysis method is used to the design and calculation of suspended-anchored retaining wall.In this paper, the author made a systematic exposition with suspended-anchored retaining wall of reliability analysis method, and compared the different calculation methods. The analyses or discussions are emphasis on the following contents.(1) The random variables, such as:internal friction angle, filling density, basal friction coefficient and base bearing capacity, were discussed that involved the suspended- anchor retaining wall of reliability design.(2)The author discussed some calculation methods of the reliability index, and applied it in suspended-anchored retaining wall of reliability design.(3)According to the reliability theory of the suspended-anchor retaining wall, established the limit state equation of overturning, anti-slip, bearing capacity the stability of.(4)Based on MATLAB software, use of JC method, Monte -Carlo method, optimization methods, developed the reliable indicator calculation program of the overturning moment, anti-slip, bearing capacity of the stability.(5)Take a certain same retaining walls of Yanan-Ansai Highway as example, the author compared the safety factor method calculation with the reliability design method calculation. The results proved whether the safety factor method or the reliability design method is safe and reliable.更多还原
