摘要
在满足挡土墙地基承载力验算要求的基础上,推导了抗倾覆安全系数的允许取值范围表达式,同时将相关参数用截面底部宽度进行表示,并给出了换算系数的关系曲线图,进而结合抗滑移稳定性要求直接进行挡土墙截面设计。算例表明,该方法简捷直观且结果可靠,可供设计人员参考。
Based on meeting the requirement of ground bearing capacity, the allowable range expression of anti-overturning safety factor is derived. The relative parameters are expressed with base width and the relation graphs of conversion factor are presented, and then the cross-section of retaining wall is designed directly by combining the stability requirement of anti-sliding. The calculated result shows that this method makes the design simple and reliable. It may be a reference for engineers.
