为了比较中美规范在挡土墙设计中安全和经济因子的异同,首先比较中美挡土墙规范中土压力计算理论的差异,再通过挡土墙算例,分别按两种规范计算主动土压力及抗滑稳定系数。结果表明,美国规范计算土压力的公式相对复杂,土压力计算结果比中国规范计算值大。中美两国规范在抗滑稳定安全因子的标准方面相近,土压力的不同使得中国规范在安全的前提下相对经济。
In order to compare the similarities and differences between safety and economic factors in the design of retaining wall between China and the United States, firstly, the difference of earth pressure calculation theory in China and the United States retaining wall code is compared. Afterwards, Pressure and anti-slip stability factor. The results show that the formula for calculating soil pressure in the United States is relatively complicated, and the calculation result of earth pressure is larger than the calculated value of China. The standards of China and the United States are similar in respect of the standards for the safety factor for anti-skid stability. The different earth pressures make China’s regulation relatively economical under the premise of safety.
