摘要
重力式挡墙是山区高速公路最为常见的挡墙型式之一,但相关技术规范、手册仅对重力式挡墙尺寸给出一个建议范围,并未阐述其尺寸影响因素间的变化关系。结合工程实际,分析挡墙断面尺寸间的影响因素,在满足其稳定性要求的基础上,综合比较得出其最佳经济断面,从而达到优化设计的目的。
Gravity retaining wall is one of the most common type of retaining walls in mountainous expressway,but the relevant technical specifications or manuals only give a proposed size range for gravity retaining wall without explaining the relations with factors influencing its size.In this paper,combining with engineering practice,the factors influencing the size of retaining wall have been analyzed,and based on meeting its stability requirements,the best economic cross-section has been obtained through integrated comparisons,therefore,the purpose of optimized design has been achieved.
