The following conclusions can be drawn.(1)A model for evaluating life cycle cost of pavements considering winter road traffic situation was proposed. An algorithm for the model which was developed by applying the sensitivity analysis of the probit stochastic user equilibrium (PSUE) was also proposed. Drivers' route choice behavior induced by deterioration of surface condition of pavements, change in traffic capacities brought by repair works in summer, and change in traffic capacities brought by antifreezing admixture dispersion in winter was endogenously expressed in the model. As a result, a plan for repair works and dispersion of antifreezing admixture which minimizes the life cycle cost by taking above mentioned driviers' behavior into account was obtained by carrying out a numerical experiment.(2)The integrated database combining the data of varieties, such as the road surface condition, the drive condition, the weather information and so on was created. As a case study using this … More database, the research solved the relation between the road surface condition and the drive condition in winter, and showed that the useful information to the traffic administrator and the road user could be created. This result showed the validity of the anti-freezing agent in the case of many, and clarified further the conditions on which that effect fades.(3)A calculation example of 2 dimensional Moving Element Method (MEM) with a vehicle model was introduced and it is verified that an interactive behavior between a vehicle and plate can be successfully analyzed by this method. The developed MEM has following advantages against conventional time-domain FEM for continuous structure under the loading due to a moving vehicle, (a) MEM can fix the loading position in the model regardless of time elapsingwhereas FEM needs large model corresponding to the moving range of the vehicle, (b) Since limited area or length near the loading point is finitely modeled for MEM, the degrees of freedom required for the analysis become smaller than those for a conventional FEM.(4)Damage evaluation method for infrastructure based on fractal analysis was developed.(5)A bond model for FRP sheet which can consider the influence of Young's modulus of resign and sheet was developed.(6)Surface protective agent which can penetrate into 40 mm depth from concrete surface was developed.

可以得出以下结论。(1)A提出了考虑冬季道路交通状况的路面寿命周期费用估算模型。提出了一种基于概率单位随机用户均衡（PSUE）灵敏度分析的模型求解算法。模型内生地表达了路面状况恶化、夏季维修工程引起的通行能力变化和冬季防冻剂分散引起的通行能力变化引起的驾驶员路径选择行为。因此，通过进行数值实验，得到了一个计划，修复工程和防冻剂的分散，最大限度地减少生命周期成本，通过考虑上述司机的行为。（2）建立了集路面状况、行车状况、气象信息等多种数据为一体的综合数据库。作为一个案例研究， ...更多信息 数据库，解决了冬季路面状况与行车状况之间的关系，为交通管理者和道路使用者提供了有用的信息。这一结果表明了防冻剂在许多情况下的有效性，并进一步阐明了这种效果消失的条件。(3)A介绍了二维移动单元法在车辆模型上的计算实例，验证了该方法可以成功地分析车辆与板的相互作用。与传统的时域有限元法相比，该方法具有如下优点：（a）可以不受时间限制地固定模型中的加载位置，而有限元法需要与车辆移动范围相对应的大模型;（B）由于有限元法只对加载点附近的有限区域或长度进行离散化建模，分析所需的自由度变得比常规FEM的自由度小。（4）建立了基于分形分析的基础设施损伤评估方法。(5)A建立了能考虑树脂弹性模量和片材弹性模量影响的FRP片材粘结模型。（6）研制了一种能渗透到混凝土表面40 mm深处的表面保护剂。少
