| 摘 要： | 阐述汽车荷载作用下挡土墙土压力的计算：现行计算方法把挡土墙路基上布置的汽车荷载,在有效范围内换算成等代均布土层厚度,计算挡土墙土压力.由于简化的假定条件,使计算结果产生较大的误差;改进的计算方法是通过解析分布长度和分布宽度的方法,计算出对挡土墙最不利的土压力,并用算例说明它的实用性.

| Abstract: | This paper deals with the pressure calculation for reuaining walls under car load. The current calculation method is to convert the car load on the retaining wall base into the load of an equivalent lager of soil with a certain thickness for calculating the pressure of retaining wall. Because the assumed calculation conditions are too simple, the calculation results obtained by the current method produce bigger errors. The improved method uses the analytic distribution length and analytic distribution width to calculate the pressure of the retaining wall under disadvantageous conditions. Moreover, the paper gives an example to explain the utility of the improved method. |
