| 摘 要： | 在挡土墙稳定性计算基本原理基础上,引入《核电厂抗震设计规范》(GB 50267-97)关于地震系数的规定,重新建立了安全相关边坡挡土墙土压力和地震角计算公式,并应用到实际工程中。对比分析显示,挡土墙按核安全边坡和一般边坡进行抗震验算时,地震系数、地震角的取值相差较大;由于按核安全边坡计算时地震力远大于一般边坡,因此稳定系数远小于一般边坡。

| Abstract: | Based on the theory of retaining wall stability calculation, the earthquake coefficient stated in Code for seismic design of nuclear power plants (GB 50267-97) was used. The calculation formulas of soil pressure and seismic angle for retaining wall of safety related slope were deduced and applied in a practical project. Comparative analysis shows that the values of the earthquake coefficient and the seismic angle are of great difference when the earthquake-resistance of retaining wall is checked in case of the safety related slope and the common slope. The earthquake force of the safety related retaining wall is highly greater than that of the common retaining wall, while the stability coefficient of them is reverse. |
