摘  要：
基于投资—效益准则,从滑坡抗滑桩结构在全寿命周期内总费用的构成和计算方法出发,构建了抗滑桩结构基于投资—效益准则的优化设计模型,通过寻找全寿命周期内总费用的最小值来实现抗滑桩结构设计的目标性能。以陕西省吴起县大路沟滑坡抗滑桩工程为研究背景,详细介绍了抗滑桩结构的初始建造成本和各项失效损失费用的计算方法和公式,以及抗滑桩结构的目标性能表达式。结果表明:抗滑桩结构全寿命周期内总费用的评估是实施基于投资—效益准则优化设计的关键。根据抗滑桩工程所处地的社会经济发展水平,依据钢筋和混凝土材料单价来确定抗滑桩结构的初始建造成本的方法是有效可行的。文中提出的关于滑坡抗滑桩结构目标性能的确定思路和方法具有一定的参考价值。

摘  要：
Based on the investment-benefit criteria,uisng the composition and calculation methods of the total cost of anti-slid pile structure in the whole life cycle,the optimization design model of anti-slide pile structure based on investment-benefit criteria was composed.The target performance of anti-slide pile structure design can be achieved by finding the minimum cost of anti-slide pile structure in the whole life cycle.Then on the basis of anti-slide pile structure of Dalugou loess landslide in Wuqi County of Shaanxi Province,the calculating methods and formulas of initial construction costs and failure costs of anti-slide pile structure,and the target performance expression of anti-slide pile are described in detail.The results show that the assessment of the total cost of anti-slid pile structure in the whole life cycle is the key to implement the optimization design based on investment-benefit criteria.According to the local social and economic development level of the anti-slid pile engineering project,the methods to calculate the initial construction costs of the pile structure based on the unit price of the steel bar and concrete are effective and feasible.The ideas and methods to determine the target performance of anti-slide pile structure have a certain reference value.
