| 摘 要： | 根据力多边形原理，推导了挡土墙有限范围填土土压力计算式，并通过算例与现行路基手册中公式进行对比，其结果显示:手册公式较文中计算式计算偏的大，据此设计的挡土墙不甚经济合理。建议完善其计算理论。

| Abstract: | According to the principle of polygon of forces,limited filling soil pressure formula of retaining wall is educed and it is compared to the formula in the current Subgrade Manual.It is shown that the result from the formula in the Manual is larger than that from the above formula.Therefore the retaining wall based on this design is not economical or reasonable and it is suggested to improve its calculation theory. |
