| 摘 要： | 为了方便分析车辆通过路桥过渡段时车内人体舒适性,提出道路-车辆-人体振动系统,在分析评价现有人体振动及舒适性评价方法与标准的基础上,根据车辆通过路桥过渡段时人体承受振动的特点,采用压电式加速度传感器测量车辆通过路桥过渡段时人体承受的竖向加速度,提出了新的人体舒适性评价方法,并以2条高速公路为例,应该用该方法进行路桥过渡段人体舒适性评价。结果表明,该方法可以更加客观准确地评价车辆通过路桥过渡段时人体的舒适程度,可为提出基于舒适性的路桥过渡段差异沉降控制标准提供理论依据。 |
| 关 键 词： | 道路工程 路桥过渡段 人体舒适性 加权加速度 均方根值 |

| Abstract: | In order to analyze the human comfort when vehicles passing through the transition section between bridge abutment and embankment,the vibration system of road-vehicle-human were put forward.On the basis of analyzing the present evaluation methods and criteria for human body vibration and comfort,the new evaluation method adopting piezoelectric acceleration sensor to measure the vertical acceleration of the human body was proposed according to the vibration characteristics.Take two existing expressways for example,this method was used to evaluate the human body comfort.The results show that the new method can objectively and accurately evaluate the human body comfort degree so as to provide a theoretical basis for the control of differential settlement of the transition section based on comfort properties.5 tabs,2 figs,10 refs. |
| Keywords: | road engineering transition section between bridge abutment and embankment human comfort weighted acceleration root-mean-square-value |
